After 16 years of nearly continuous economic growth, we Australians can rightly say we have never had it so good. However, with that prosperity has come very high energy consumption and we now face the challenge of reducing this consumption or making it less environmentally damaging — we probably need to do both. The incoming Labor Government has set itself an ambitious target to cut greenhouse gas emissions by 60% by 2050. This will involve research and development, business facilitation and investment in renewable energy sources. Cleaner energy from coal is a foundation objective along with an emissions trading scheme. Both will take substantial effort to develop and careful commercialisation if the goal is to be achieved. Meeting the targets will necessitate development of a broad range of policy options and examination of all energy sources, uses and impacts. The Australian Institute of Energy has a role to play and we look forward to participating. The national Board is encouraging Institute branches to conduct seminars and workshops that address the technology and market options for increased energy efficiency and reduced environmental impact. Introducing PAMS To improve services to AIE Members and meet our increasingly demanding corporate governance and regulatory obligations, the Institute has contracted our secretariat, accounting, website and membership management tasks to Professional Association Management Services (PAMS).

Contact details:Joy Claridge [email protected] (03) 9596 3608 0402 078 071 EnergyNews — Volume 26 No. 1 March 2007 AIE in Newcastle The AIE Board held its final meeting for 2007 and the Institute held its national 2007 AGM at the CSIRO Energy Centre in Newcastle on 27 November 2007. Board members and Newcastle branch members enjoyed a tour of the facility, including the wind turbines, photovoltaic system and cogeneration plant. It has taken nearly 20 years to bring this world-beating technology to the market. Much of that time has gone into basic research, mainly in the areas of optimising blade aerodynamics for power, starting performance, and noise. Ideal blades, however, are complex 3-dimensional shapes and raise many structural and fatigue issues that we have only recently solved.1 The other main innovation is in the controller. We are working closely with Zener Electric in Sydney to adapt their motor speed control technology for use as wind turbine controllers. Only a few standard extra components are required, and the result is a very cheap controller that is also an inverter. In other words, the purchaser of our turbine does not have to spend an extra A$3,000–4,000 on an inverter. The grid-connected form of the turbine is actually cheaper than the battery-charging one. AIE members on tour at CSIRO Energy Centre After the tour, David Wood, from the School of Engineering, The University of Newcastle, and Aerogenesis Australia, presented on wind energy research in Newcastle. A summary of his presentation follows. The commercialisation strategy combines leading-edge technology (pun intended) with the maximum use of standard, mass-produced components. We believe this will transform the manufacture of small wind turbines from the present paradigm of small volume and high cost to massproduced cheaper units. The 5 kW turbine will enter the market at around A$20,000 which is significantly cheaper Taking newcastle’s wind energy research to the world Research and development of small wind turbines began at Newcastle University in the mid 1980s. In 1992 we installed our first 5 kW test turbine at Waratah, next to the university. This was followed in 1997 by another 5 kW turbine at the much windier site at Fort Scratchley at the entrance to Newcastle Harbour. Since 2001 we have had a 500 W turbine running on the top of the engineering building on campus and plan to install an advanced Aerogenesis 5 kW turbine on campus by mid 2008. Commercialisation of the technology began with Energy Australia in 1997, but, unfortunately, their ‘Power On’ turbine project did not proceed. After deciding that we could not rely on others to take us to market, Aerogenesis was started in 2004 to commercialise the (then) latest version of the 5 kW turbine whose blade and controller design had been patented. The Australian Greenhouse Office is now supporting the installation of five demonstration turbines in China and Australia (including the one on campus) and commercial production will follow soon. Aerogenesis 5 kW demonstration turbine 1 This work was described in a paper delivered at the Solar 07 conference in Alice Springs, a copy of which can be obtained by emailing [email protected] EnergyNews — Volume 26 No. 1 March 2008 than any competitor. We anticipate eventually reducing the price to around A$15,000 when production is fully underway. The 5 kW turbine will produce about 25 kWh per day at a good (windy) site. Because of their high cost, small turbines have been used traditionally for battery charging. The much lower cost of our technology allows us to explore a new market niche — grid-connected turbines in areas where large turbines are unsuitable. Typical sites include railway and freeway corridors, industrial estates, parking areas, schools and universities. Combining the income from electricity sales and carbon credits with the ‘image revenue’ from advertising that associates the sponsor with this green energy makes the turbine a very attractive investment. In countries that have higher base electricity prices, such as most of Europe, the turbine will return its investment in a few years. Aerogenesis is currently negotiating a major export project with a leading energy supplier in the United Kingdom. We are also working on other projects. Aerogenesis and university staff are voluntarily supporting a project in Nepal to develop an indigenous small turbine for (very) remote power production. The next Aerogenesis turbine will probably be a 30 kW unit as this is the largest rating that can be grid-connected without requiring a generator’s licence. The controller technology becomes relatively cheaper with increasing power, so the 30 kW will be even more cost-effective than the 5 kW; but may well have a more limited market. Research and development continues. A web-based monitoring and data gathering system will allow predictive maintenance and performance assessment. Our optimisation work is being extended to the tower design which becomes more critical as size increases. There are two main developments in controller strategies. The first is in maximum power point tracking (MPPT), ie ensuring that the turbine extracts the maximum power from the wind. MPPT is used in many turbines, but current strategies are based on steady turbine performance which is not necessarily the optimum strategy in a continually varying wind. This issue is particularly important for small turbines as their blade inertia is relatively much smaller than for large turbines. Secondly, we are exploring the power producing capacity of the turbine in high wind. Turbine power rating is nominal, and high power occurs when there is plenty of cooling air for the generator; so it may well be possible to extract, say, 7 kW from a 5 kW turbine at wind speeds greater than the rated speed. These high winds may not occur very often but the disproportionate power they produce can significantly increase the average power output. Testing a wooden blade for the Nepal project EnergyNews — Volume 26 No. 1 March 2008 Coal Challenges facing the Australian coal industry Based on a presentation to Canberra Branch by Burt Beasley, Director Technology and Innovation, Australian Coal Association, on 19 December 2007. Coal is a dominant force in the Australian economy, as an export product and source of electrical power. In terms of total world coal reserves, Australia has the 4th largest black coal resource base (approximately 75 billion tonnes of demonstrated black coal) and the 2nd largest brown coal reserves. Coal is Australia’s largest merchandise export, worth A$24.2 billion in 2005–06, and Australia is the world’s largest coal exporter, accounting for around 30% of world coal trade. The Australian coal industry is a major regional employer with around 30,000 workers directly employed at coal mines. Many more jobs are directly or indirectly associated with the industry. Coal accounts for around 80% of electricity generation in Australia, and this is the basis for Australia’s comparative advantage in power, supporting energyintensive industries such as aluminium, steel and cement. Despite these facts, Australia accounts for only 6% of world coal production. Australia’s use of coal accounts for 0.4% of global greenhouse gas emissions, and Australia’s export coal accounts for a further 1.3% of global greenhouse gas emissions; in total less than 2%. If Australia withdrew from the world coal market there may be some substitution out of coal, but it is far more likely that the gap left in the market would be filled by supplies from other countries, particularly Indonesia and China. The impact on global greenhouse gas emissions would be minimal, not only because other countries would ramp up supply but also because Australian coals are of a very high quality, and substitution with coal from countries such as China and India, which have a very high ash content, may actually have a negative greenhouse impact. Coal21 Initiated by the Australian coal industry, the COAL21 Program is aimed at realising the potential of advanced technologies to reduce or eliminate greenhouse gas emissions associated with the use of coal. COAL21 is a collaborative partnership between the Australian and state governments, the coal and electricity generation industries, the research community and unions. to stop the CO2 entering the atmosphere. This is either through postcombustion capture or oxy-fuel combustion. The pathway at the bottom is based on gasification technology, which converts the carbon and hydrogen in coal into CO2 and clean burning hydrogen gas. The CO2 that is captured using any of these technologies is compressed into a liquid state. Under normal pressure, if you cool CO2 it will go straight from a gaseous state to the familiar solid state — dry ice. However, under higher pressures CO2 becomes a ‘supercritical’ liquid. This liquid CO2 can then be injected deep underground into porous rock structures. The pressures at these depths (over 600–800 metres) maintain the CO2 in a liquid state and it is permanently trapped. Australia has undertaken world-leading research into identifying suitable geological structures. The projects listed on the right hand side are those that are already underway or have been proposed to investigate these processes further. The first carbon storage pilot project — the Otway project — will commence injection of CO2 in 2008. Funded by the world’s first voluntary production-based levy on black coal producers, the COAL21 Fund is spending more than A$1 billion over 10 years in support of technologies in the demonstration phase, with the objective of significantly reducing the greenhouse gas emissions from coal. The priority technologies are carbon capture (postcombustion capture through various processes, oxy-fuel combustion, precombustion capture via gasification) and carbon storage (in depleting oil and gas reservoirs, in saline water saturated reservoir rocks (aquifers), and in and below coal seams). There are two main pathways for clean coal technology. The following slide shows the work being done through some of the pilot programs and demonstration projects to develop these technologies in Australia. The pathway at the top is based on applying carbon capture and storage technology to conventional coal combustion technology, For further information, see www.coal21.com.au or www.australiancoal.com.au, or email burt.beasley@ australiancoal.com.au EnergyNews — Volume 26 No. 1 March 2008 Biogas An untapped source of energy Presentation to Melbourne Branch by Torsten Fischer, Managing Director, Krieg & Fischer Ingenieure GmbH, 23 June 2007. Torsten Fischer is one of the world’s leading experts on the application and utilisation of biogas technology. Based in Göttingen in Germany, in the past 15 years, Krieg & Fischer Ingenieure has built around 120 biogas plants in Germany, other European countries, the United States, Canada and Japan. We usually associate biogas with the recovery of gaseous energy from municipal waste water treatment plants, such as Werribee and Carrum. Using a number of interesting plant photographs, Torsten Fischer showed that biogas can be made from a multitude of waste materials, including potato peel, apple residue, sugar beet residue, kitchen waste, fats and grease, agricultural waste, and waste from cattle feed lots, pig farms, rendering plants, canneries and bioethanol plants. Fats (eg old chip fat) deliver the highest yields, whereas manure and kitchen waste among the lowest. Figure 2: Schematic of biogas power plant The biogas is rich in methane and is therefore most suitable as a fuel for a gas engine-driven power generation plant. Power output varies from several hundred kW to upwards of 8 MW. Mr Fischer described how biogas power generation had grown over the past 15 or so years. In Germany, where there are now more than 3,000 biogas power plants in operation and the generation of biogas power exceeds wind power, the industry is supported by an attractive guaranteed electricity buyback price (see Figure 3). Figure 1: Biogas plant in Werlte (90,000 m³ manure & 20,000 m³ fats per annum) Source: Krieg & Fischer Ingenieure GmbH The treatment of these materials does vary, but typically it follows a series of logical process steps (see Figure 2): 1. Feedstock material is collected and stored. 2.Pretreatment, which will vary with the nature of the feed, but can involve grinding, sieving, homogenisation and removal of foreign objects. 3.The prepared feed is then semi-continuously added to a large fermenter or digester and blended into the reacting ‘soup’ using a side- or top-entry stirrer. Bacterial action anaerobically breaks down the substrate in essentially four sequential phases – hydrolysis, acidification, acetogenic transfer, then methanogenic formation of methane. External heating may be applied to keep the reactor temperature at an acceptable level. 4.Biogas is released and collected for further use — typically in a gas engine for the generation of electric power. 5. Nondigestible residual material is then removed. EnergyNews — Volume 26 No. 1 March 2008 Figure 3: Payment for electricity from biogas in various countries The industry developed partly in response to a general public dislike of nuclear power and government bans on the use of raw manure and waste food. The need for better management of the environment accelerated the level of interest. Instead of putting farm waste back on the fields where it would biodegrade and release significant quantities of methane into the atmosphere (methane is a far more intense greenhouse gas than CO2), the government legislated for more effective control and use of these wastes. Here in Australia, site location, access to the grid and government support could make this untapped biogas source of energy a serious option for renewable energy power generation.

Can California have adequate energy while meeting stringent emission restrictions? California’s green Republican governor, with the support of the Democratic-controlled Legislature and the consent of the California Public Utility Commission (CPUC), has passed a number of laws collectively aimed at reducing that state’s greenhouse gas emissions to 1990 levels by 2020. How will California meet this goal? How much will it cost? Will it be worth the effort? What might the implications be for the United States as a whole or, even, globally? Most importantly, should resource-rich Australia take notice? Perry Sioshansi offered a synopsis of how California, the 6th largest economy in the world, is trying to meet its self-imposed targets without scuttling its vibrant economy. Amid great fanfare in 2006, California passed an ambitious law to reduce its greenhouse gas emissions to 1990 level by 2020. Meeting the goal of the Assembly Bill 32 (AB32) requires a 25% reduction in emissions compared to a business-as-usual scenario while the state’s population is expected to rise by 41% by 2020. At the time of bill’s passage, there were a few educated guesses on how much it might cost but the politicians were focused on the positive aspects of the law such as the multi billion dollar development of green and clean technologies. Since then, a few attempts have been made to come up with rough cost estimates for meeting the law. This is not easy, partly because AB32 is largely mute on the crucial details on how the target is to be met and how the burden shall be spread among various sectors of the economy – principally the transportation, power generation, and a handful of other major industries. How much will it cost? One early study conducted by the Electric Power Research Institute came up with a US$100– 511 billion price tag through 2050 or roughly 0.2–1.2% of state GDP. The wide range reflects the uncertainties in how AB32 may be implemented. Another unknown is whether other western states will join California in similar efforts and/ or whether national or international greenhouse gas limits will be introduced during the interim years. If there is any consensus among the economists looking into this, it is that the ultimate cost will critically depend on implementation details — principally burden allocation among various sectors. Simply stated, the costs will be less if the target is to be met through a broadly-based scheme such as a capand-trade system or a broad, technology-neutral carbon tax. It will cost more if multiple uncoordinated sector and fuel-specific targets are established and enforced through separate command-and-control mechanisms, as appears likely. Regulators and policy makers favor the latter since they are more familiar with such schemes and because there is less transparency on the ultimate costs. Studies done elsewhere reach similar conclusions. Targets would be easier to meet if the entire western region of the United States, or the entire country, were to follow a similar path. The CPUC, the California Energy Commission (CEC) and California Independent System Operator (CAISO) have been holding quarterly meetings to examine the options. Speaking during their latest meeting in mid-December 2007, Julie Fitch, Director of Strategic Planning with CPUC, ventured that meeting the requirements of AB32 “may call for utilities to increase electricity and natural gas rates by about 30% on average by 2020.” That’s admittedly a rough guess; but indicative of the cost burden that may be required, and this does not account for costs on other sectors of the economy, notably transportation and heavy industry — of the latter there is relatively little in California. Ms Fitch’s rough estimate is based on a preliminary CPUC analysis, which indicates that California’s energy sector can meet the AB32 target by ramping up the state’s energy efficiency efforts to ‘unprecedented’ levels and by boosting the renewable portfolio standard (RPS) to 33% by 2020, as already envisioned through an Executive Order issued by Governor Arnold Schwarzenegger. Due to potential for ‘leakage’, other western states would also have to boost their own RPS and energy efficiency efforts for California’s greenhouse gas reduction targets to be met. Fitch said that according to ‘very preliminary’ CPUC estimates, roughly one-third of the utility rate increases could come from energy efficiency costs with the balance from increased RPS. While the numbers are not precise, Fitch said she wanted to convey the magnitude of potential rate increases associated with meeting AB32. We can expect to hear more on this in the years to come. * Menlo Energy Economics is a energy sector consulting firm based in San Francisco.

EnergyNews — Volume 26 No. 1 March 2008 Victoria’s Energy Future Roadmap to Victoria’s Energy Future — a 2020 Vision Presentation by the Hon Peter Batchelor MP, Victorian Minister for Energy & Resources, to AIE Melbourne Branch on 8 November 2007. I believe that we are approaching a period of significant change within the energy sector. The Victorian Government’s current energy policy is to ensure energy is affordable, efficient and secure; supplies are delivered reliably and safely; and energy production and use becomes more sustainable and produces less greenhouse gases. This last point recognises that climate change is the biggest environmental challenge we face, and that tackling it will require significant reductions in greenhouse gas emissions. The year 2020 Let’s just take a moment to think about energy projections in the year 2020. According to both Victorian Government data and the Australian Bureau of Agricultural and Resource Economics (ABARE), ● Victorian economic growth will average a healthy 2.7% per annum, noting that economic activity is a key driver of energy consumption; ● Victoria’s population will be just under 6 million; ● the market penetration of air-conditioners in Victoria will rise from about 50% to around 70%; ● further, there will be a shift from evaporative to refrigerative models of air-conditioning which use more energy; ● without the intervention of government initiatives, Victoria’s energy consumption could rise by approximately 16%; and ● even more worrying, our peak energy use could rise by over 20%. Early action is necessary The Brumby Government knows that early action to address climate change is necessary to secure our energy future. The Stern review, headed by Nicholas Stern, a former head of the UK Treasury and World Bank economist, has confirmed that EnergyNews — Volume 26 No. 1 March 2008 the earlier action is taken to combat climate change, the less expensive it will be. The Brumby Government has already taken significant steps to reduce Victoria’s ‘carbon footprint’. The main way that we have done this is to advocate for an emissions trading regime as the most cost-effective way to cut greenhouse emissions. Imposing a cost on carbon will encourage investment in alternative and cleaner energies and technologies like carbon capture and storage. Since 2004, we have worked with the other states and territories to develop a preferred model for a national emissions trading scheme (ETS). We are of the view that emissions trading should be complemented by a range of other greenhouse gas abatement measures, including energy efficiency, support for innovation in energy technology and the continued development of the renewable energy sector. Energy efficiency We recognise that reducing energy use is the quickest and cheapest way of reducing greenhouse gas emissions in the short term. Energy efficiency offers both environmental and economic benefits. For example, independent analysis has found that if Victoria reduces its energy use by 1% each year, Gross State Product would increase by $360 million and greenhouse emissions would be cut by 6.2 million tonnes. However, there are a number of market barriers to energy efficiency measures, including the poor availability of information, split incentives for tenants and landlords, behavioural inertia, and uncertainty about returns from investment in energy efficiency initiatives. That is why we have introduced new energy efficiency initiatives. 1. The Victorian Energy Efficiency Target (VEET) scheme, introduced into Parliament in early November 2007, will provide an incentive for cost-effective energy-efficient activities to reduce energy consumption and greenhouse emissions from the residential sector. 2. $14 million is being invested over the next four years to introduce a rebate program for retrofitting or replacing old appliances with energy-efficient ones. 3. $2 million is being invested to expand the Energy Task Force program, to retrofit public housing estates with energy efficiency improvements. 4. Sustainability standards for Victorian homes and buildings are being improved by establishing, for example, minimum standards for heating and cooling appliances in new homes. 5. Feed-in tariff provisions will be strengthened to ensure that households (and small businesses) that feed renewable energy back into the electricity grid are paid a fair price. 6. From 2008 all houses sold in Victoria will be required to be fitted with water saving devices, such as low-flow showerheads. 7. The successful ‘Black Balloon’ campaign will be extended to encourage energy conservation. Support for innovation Reducing energy demand is one way we are tackling the climate challenge. But what about the use of brown coal for power generation? Given that brown coal is likely to remain the most abundant and low-cost primary energy source available to Victoria for some time, how can we continue to use our most abundant resource and enjoy the wealth it offers in a responsible and sustainable way? Deep cuts, and near-zero emissions from the Latrobe Valley can only be achieved through the development of technology. That is why we are investing around $180 million under the Energy Technology Innovation Strategy (ETIS) for research, development, demonstration and commercialisation for lower-emission technologies. These include cleaner brown coal technologies and renewable energy projects. For example there are opportunities to improve the greenhouse efficiency of our existing power stations and to trial new technologies too. That is why we are contributing $30 million for the development of a demonstration project at Hazelwood Power Station to retrofit brown coal drying technology. We have contributed $6 million to the CO2CRC for a carbon dioxide storage trial in the Otway basin, and we are funding $50 million for the construction of a ‘clean coal’ demonstration power station based on coal drying and gasification technology. Earlier this year we released an issues paper Towards near-zero emissions from Latrobe Valley Brown Coal. The response from industry and the community to this paper has been tremendous. We are currently developing the policy framework that will allow us to deliver on this vision. Support for renewable energy We know that there is no ‘silver bullet’ that will tackle climate change. Instead, there is a suite of measures that will allow us to tackle the challenge on a number of fronts. That is why when the Commonwealth Government decided not to increase its Mandatory Renewable Energy Targets, the Victorian Government stepped into the breach and created the Victorian Renewable Energy Target (VRET) scheme which commenced on 1 January 2007. VRET sets a target of 10% of Victoria’s electricity consumption to be met from renewable sources by 2016. Since the announcement of the VRET scheme more than 1,000 MW of wind energy projects, valued at over $2 billion, have been confirmed. We have contributed $50 million to support the development of one of the world’s largest solar power stations, to be built in north-west Victoria. We have established an $8 million Renewable Energy Support Fund to support renewable energy technology, and we are putting our money where our mouth is by purchasing 10% of the government’s own energy in the form of Green Power, with a plan to increase this to 25% by 2010. We are also installing solar panels on 500 school and community buildings. Smart meters We are working towards the wide-scale accelerated rollout of smart metering across Victoria. This will give consumers better information about their energy use, and a greater range of options to improve their energy efficiency. Smart metering systems that enable two-way communication will see the deployment of new technology capable of communicating with displays and other in-home devices, giving customers access to better energy information and control. We believe that energy consumption information used in conjunction with cost-reflective or dynamic pricing will provide an incentive for consumers to shift their energy demand away from peak times and reduce their bills. For example, sensors on high-power items such as air-conditioners, pool pumps and slab heating could communicate with the smart meterrelated technologies to adjust their operation to suit certain pricing schedules and to save consumers money. As an aside, today we have taken another step towards removing regulation from energy pricing here in Victoria. Due to the maturing of the competitive Victorian energy retail market, small businesses can get better value for money on their energy bills. The State Government will no longer set a standard price for electricity and gas for small business customers from January 2008. We are genuinely moving to more cost-reflective pricing for energy here in Victoria. Conclusion In conclusion, the Brumby Government is working to provide a clear policy setting, the regulatory framework and the right incentives to encourage the right kind of investment, which will carry Victoria into the future. As I have outlined, we are tackling the climate change challenge in a number of ways. We are working with industry to deliver practical projects and effective scientific research to improve the environmental performance of our energy sector, including significant investment in renewable energy and innovation. We are leading the way in national reforms to provide greater benefits for investors and consumers including support for a national emissions trading scheme, which will create the signal for the next wave of investment in Victorian energy infrastructure. EnergyNews — Volume 26 No. 1 March 2008 Special Feature Energy and Water: An electric issue This special feature could just as easily been called ‘Electricity and Water’, because some of the major issues around the relationship between energy and water derive from the use of scarce water in electricity production and the electric energy-intensity of water production. This special feature starts with an overview from Debborah Marsh, who is completing her PhD at the University of Technology Sydney, and Associate Professor Deepak Sharma. Ms Marsh’s thesis examines the links between energy and water policies and investigates the implications of the links for the Australian economy. In her article, she identifies some of the important links between electricity and water; examines how the links are currently impacting the electricity industry, and suggests ways to improve current understanding, in order to develop a more adaptable and resilient industry. Among these links are the high energy intensity of desalination and the high water intensity of electric power generation. Following this introduction, Associate Professor Sandra Kentish and Professor Stephen Gray deliver a more technical paper around the work of the Advanced Membrane Technologies for Water Treatment Research Cluster, which is working towards solutions that decrease the use of energy to provide sustainable and economic water solutions by developing membrane research capacity and new technologies. This is followed by look at the dry cooling tower technology of CS Energy’s recently commissioned Kogan Creek Power Station. The complex relationship between water and energy in Victoria’s brown coal power industry is reviewed by Dr David Allardice; and Itron’s Paul Nelson discusses meter data collection trends in both the water and energy sectors. In the final article — Marine Power: Waves, tides & currents — Andrew Taylor of AMOG Consulting takes us offshore to reveal the energy secrets of the ocean. EN The Links between Energy and Water By Debborah Marsh (PhD student), Institute for Water and Environmental Resources Management, and Deepak Sharma, Associate Professor and coordinator of the Energy Planning and Policy Program, Faculty of Engineering, University of Technology Sydney Energy and water are fundamental to our economic and social wellbeing. Both industries have fulfilled important roles in Australia’s past, enabling progress in rural and urban Australia. Now, energy and water issues are being discussed at all levels of government and within the community. Central to these discussions are microeconomic reforms being implemented by state and national governments. These reforms have, over the past decade or so, introduced significant changes to the structure, ownership and regulation of both industries. In terms of structure, previously vertically-integrated utilities were functionally unbundled into wholesale, network and retail segments. Ownership shifted towards the private sector, as the competitive wholesale and retail segments were opened to competition. Further, new regulatory arrangements covered price setting and service delivery and enabled third party access to the monopoly segments. Concomitant to the reform debate in recent years is scientific consensus on climate change. Climate scientists forecast increased weather variability, such as extreme droughts and floods, as a result of the warming of the earth’s atmosphere. For a country already afflicted by drought and flooding rains, such forecasts do not bode well. Emerging from these discourses is an awareness of how energy and water are inextricably linked. Recent policy 10 EnergyNews — Volume 26 No. 1 March 2008 reforms, however, have appeared to ignore the constraints imposed by the nexus, with unintended consequences. Links between electricity and water? Upstream links ‘Upstream’ primarily refers to wholesale electricity generation and bulk water supply. It may also refer to coal dewatering and subsequent water reuse. Electricity generation is highly dependent on water for steam production and cooling, or in the case of hydropower, kinetic energy. Water intensities vary significantly for different generation technologies. This is evident in the results of our modelling work (see Table 1). Hydropower used significantly more water compared to other technologies, however, this water is returned to the environment for downstream users. Of the remaining technologies, coal-fired consumed the greatest amount of water, followed by combined cycle gas turbine. Cogeneration and gas turbine consumed the least. In the case of cogeneration, water was sourced on site from coal mines, which reduced reliance on mains water. Table 1: Water intensities for electricity generation technologies in NSW (2000–01) Selected generation technologies Downstream links kL/MWh generated Coal 1.70 Combined cycle gas turbine 0.99 Gas turbine (oil) 0.01 Cogeneration 0.01 Hydro 2217.07 Renewables 0.30 Energy sources such as biomass, hydrogen and nuclear are viewed by proponents as viable alternatives that would reduce the electricity industry’s greenhouse gas emissions. Uptake of these technologies, however, may result in water trade-offs. Biomass, for example, requires water for irrigation and would compete with food crops for water during dry periods. Hydrogen may be produced by reforming fossil fuels or electrolysing water. The latter method does not generate fossil fuels directly, but would require reliable sources of water. Nuclear power is considered by proponents as a ‘green’ alternative to coal, yet it consumes between 30–50% more water than a coal-fired power station (EPRI 2002). In the water industry, indirect potable reuse (IPR) and seawater desalination are alternative bulk water supply options. IPR refers to highly-treated effluent that is introduced into drinking water catchments, where it is diluted with surface water prior to being retreated for potable use. Both IPR and desalination require high levels of treatment that typically includes membrane filtration and reverse osmosis. For example, based on best available technology that incorporates energy recovery, seawater desalination consumes approximately 4 kWh per cubic meter of water produced. Table 2 compares the electricity intensities of desalination and IPR with other water treatment processes. Table 2: Electricity intensities for water treatment processes Water treatment process kWh/kL produced Conventional surface water treatment 0.4 – 0.6 Brackish water desalination 0.7 – 1.2 Reclamation of municipal wastewater (eg IPR) 0.8 – 1.0 Seawater desalination 3.0 – 5.0 (Source: Voutchkov 2005) Transportation links Transportation links comprise the use of electricity to move water, which is heavy and bulky. These links include groundwater extraction, bulk surface water transfers, retail water distribution and wastewater collection. It is estimated that water transportation consumes up to 7% of world energy production (James, Campbell & Godlove 2002). Downstream links refer to electricity for water and wastewater treatment, electricity recovery in the water industry and water and electricity use by consumers. Water and wastewater treatment processes rely heavily on electricity. Disruption to electricity supply would have severe public health ramifications for the water industry. As a result of the Californian Energy Crisis in 2001, water utilities in the Unites States explored options to safeguard supply, including the installation of renewable technologies. Elsewhere, water utilities are generating electricity from within their systems. Sydney Water, for example, is expanding the use of biogas from its sewage treatment plants and will soon generate hydropower from wastewater flows. Demand management programs are being implemented across Australia in both the water and electricity industries. These programs should slow the growth in demand, with flow-on effects for both industries due to the embedded electricity in water and embedded water in electricity. Indeed, a recent study in the United States concluded that “end use constitutes the largest component of energy embedded in the urban water cycle” (Cohen, Nelson & Wolff 2004). Impact on the electricity industry The potential impact of the nexus between the electricity and water industries is significant, particularly in the context of reform. Market mechanisms have already resulted in alarming trade-offs, because there has been no integration of energy and water policies. These trade-offs include: reduction of electricity generation due to water shortages; low electricity prices stimulating trade with little regard to regional water shortages; and trade-offs between generators, irrigators and the environment (in terms of emissions and water for river health). In 2007, Snowy Hydro reduced water releases from its dams to downstream irrigators along the Murray and Murrumbidgee Rivers due to water shortages. The company maintained that it acted in accordance with its licence. Industry observers, however, suggested the company was storing the scarce water to produce power during peak summer demand, when electricity prices are highest in the NEM (National Electricity Market). The trade-off is further exacerbated by Snowy River’s allocation of water for environmental flows. In 2000, it was agreed to return 21% of average natural flow to the Snowy River due to its poor environmental state, which represents 150 GWh of foregone electricity for Snowy Hydro. Water shortages have impacted generators elsewhere. In NSW smaller hydropower plants have reduced generation output (S. Gough, pers com). In Victoria, similar reductions in hydropower output have forced the use of more expensive and more greenhouse-gas intensive generation options to meet demand, reportedly pushing up the price of electricity in the wholesale market by more than 80% in peak times (Gordon & Kleinman 2007). In Queensland, cheap electricity is being exported from Swanbank and Tarong Power Stations to NSW via the EnergyNews — Volume 26 No. 1 March 2008 11 NEM. Both power stations are sourcing cooling water from Brisbane’s main drinking water supply, Wivenhoe Dam, despite the imposition of water restrictions in the region, and despite sufficient capacity in NSW to meet its own demand. It was reported that Swanbank and Tarong Power Stations cut back production by 20% and 70% respectively due to water restrictions, at a cost of approximately $1 million a day for the Queensland Government (Ludlow & Wisenthal 2007). Water shortages are already influencing investment decisions in the electricity industry. For example, Swanbank and Tarong will soon use recycled water from the Western Corridor Recycling Project, in order to reduce the reliance on fresh water. It is estimated that this move will cost several times more than the A$200–300/ML now being paid for water from Wivenhoe Dam, adding A$5–10/MWh to the current generation cost (A$35) (Roberts 2007a). The new Kogan Creek power station in Queensland uses dry cooling tower technology which reduces water consumption by approximately 90%, although some thermal efficiency may be lost. In Victoria, Snowy Hydro acquired two gas-fired power stations in 2007 to enable the company to meet its contractual obligations when water levels in its dams are low. As part of Snowy Hydro’s EPA licence, generation from the gas-fired stations is restricted in order to control emissions. Snowy Hydro, however, has already requested that the restriction be eased, because of the lack of water for hydropower generation. Preparing for the future Water security is key to energy security, yet recent policy reforms fail to account for this, with unintended consequences. There is scope for the industry, with sound policy support, to improve its preparedness for the future. Some ways forward are: • Greater ‘climate change’ accountability in the industry, through carbon pricing and increased support for clean energy technology. • Improved understanding of the links between price and consumption of electricity and water, particularly in the context of the NEM. • Careful consideration of water resources in investment decisions. This includes choice of electricity generation technology and cooling system, location of plants, and the needs of other water users, including the environment. • Identification of the links between electricity and water in the wider Australian economy. In particular, quantifying embedded electricity and water consumption of key economic sectors, and understanding if the links have consequences for the application of policies in other sectors. • Understanding of the social implications of the links, such as the impact on rural livelihoods, and how the value that customers place on water and electricity services impacts on consumption behaviour.

EN Energy and Desalination By Associate Professor Sandra Kentish, University of Melbourne, and Professor Stephen Gray, Victoria University As Australia moves to secure water supplies for major urban areas, reuse, recycling and water desalination programs are becoming an important component of city water strategies. While primary and secondary water treatment processes for water reuse appear to be financially and technologically viable, the energy consumption and subsequent greenhouse gas emissions associated with the desalination of both recycled brackish water and seawater are of major concern to the community. Traditionally, desalination processes used energy-intensive distillation technology. In this case the water was simply boiled, with the condensed vapor providing substantially pure water. More recently, membrane-based systems, principally reverse osmosis (RO), have been commercialised. 12 EnergyNews — Volume 26 No. 1 March 2008 Indeed, almost all major desalination facilities in operation or in planning in Australia use RO membranes. An RO membrane consists of a thin polyamide selective layer that is less than one micron thick. Flow through this selective layer is thought to be by a solution–diffusion mechanism. That is, the water molecules dissolve into the free spaces between polymer chains and then diffuse across the membrane in a dissolved state. The voids within the polymer are transient and typically of Angstrom to nanometer size. Ionic salts (principally sodium chloride) are rejected by the membrane because of their larger size but also because these charged species are repelled by the membrane surface which is also charged. A typical desalination membrane will reject 99% of the salt ions. A support layer, composed of microporous polysulfone or other similar plastic, provides mechanical strength without further restricting flow. The flat sheet composite membrane is usually wound into a spiral orientation that allows up to 1,000 square metres of membrane area per cubic metre of volume. RO processes are generally more energy efficient than distillation, but still consume large quantities of energy. Indeed, energy costs currently represent 40–50% of the cost of desalinating seawater. Fundamentally, a large amount of energy is required to overcome an intrinsic thermodynamic barrier. That is, we are trying to produce water by making a salty solution more salty, and this goes against the laws of thermodynamics. The pressure that needs to be overcome to remove water molecules from a salt solution is known as the osmotic pressure — for seawater this is around 27 Bar. In fact, seawater desalination requires around five times more energy than tertiary treatment of brackish or recycled water, due to the high salt content. Additional energy is required to overcome the hydrodynamic or frictional resistance of the membrane. Further, any fouling or scaling on the membrane surface can have a significant impact on energy requirements. As the selective membrane layer is often only 0.1 micron thick, even small deposits of foulants can dramatically increase the thickness of the layer through which the water must penetrate. A buildup of salts rejected by the membrane within the foulant layer can also lead to a much greater osmotic pressure within this layer than for a clean membrane. The energy demand has been reduced significantly over the past few years through improvements in the upstream pretreatment of the feedwater to remove foulants and through the use of energy recovery devices such as Pelton turbines. These mechanical devices recover the pressure energy used in compressing the feedwater to RO pressures (~60 Bar for seawater systems). RO membranes at Sydney Olympic Park’s wastewater reclamation plant In May 2007, the CSIRO Water for a Healthy Country Flagship program launched an Advanced Membrane Technologies for Water Treatment Research Cluster with a goal of further reducing this energy demand. The cluster involves nine Australian universities and a number of research groups within the CSIRO. Its aim is to investigate novel membrane materials and modifications to membrane surfaces to reduce both the hydrodynamic energy demand and the susceptibility to fouling. The cluster will use nanotechnology, biomimetics and functional materials to deliver new innovations in membrane technology and cost-effective and highly-efficient water recovery systems. Molecular modeling and computational fluid dynamics will be used to better understand the way that membrane materials interact with water, salts and foulants. Building on this knowledge, the team will characterise and develop predictive computational models of the separation, fouling and transport processes occurring in inorganic and organic membranes. Other team members will use this information to build novel inorganic, organic and hybrid membrane structures that are more fouling resistant and/or offer less hydrodynamic resistance. A desalination membrane test centre is being developed at the University of Melbourne. This will initially compare the performance of a range of commercial membranes. As other team members develop novel membrane materials, we will be able to assess their performance relative to their commercial counterparts. The membrane separation performance in both pure sodium chloride as well as mixed salt solutions will be evaluated as well as their fouling resistance. There are fundamentally two types of foulants that need to be assessed. Scaling arises from the precipitation of inorganic salts, such as calcium sulphate. This forms a thin but tenacious layer on the membrane surface. Biofouling arises from the adsorption of organic constituents (usually referred to as Natural Organic Matter or NOM) from the feedwater that can in turn serve as a substrate for biological growth. Extracellular polymeric substances, especially polysaccharides, are viewed as the major constituent of the resulting slime layer. Addition of very low levels of chlorine directly to the feedwater stream can be used to minimise biological fouling. However, most polyamide membranes fall apart if exposed to high levels of chlorine. Therefore, a further aim is to evaluate membrane materials or surfaces for their resistance to chlorine degradation (in collaboration with the University of Texas). Mechanisms for reducing membrane resistance include the use of heated feedwater which increases the water diffusion rate and thus increases the flux for a given osmotic pressure. Alternatively, membrane distillation can be used. In this case, heated water is passed on one side of a membrane and pure water vapor passes through the pores. Such processes have the potential to utilise low-grade heat from power stations and other industrial processes, or solar energy. However, the commercialisation of such systems is again limited by the rapid increase in fouling that occurs as temperature increases. With membrane distillation, super hydrophobic membrane surfaces are also required to prevent membrane pore wetting. If pore wetting occurs, salty water is able to pass the membrane and contaminate the product water. Scaling of membranes, as occurs for RO processes, is also an issue for membrane distillation when treating waters with elevated levels of scaling ions such as RO brine concentrate. Standard microfiltration membranes have been used for membrane distillation in the past, but renewed interest in this technology now has many membrane suppliers developing membranes for membrane distillation. High-flux membranes are being developed, overcoming one of the main limitations of previous membrane distillation systems. EnergyNews — Volume 26 No. 1 March 2008 13 Research into membrane distillation and these associated problems will form the focus of work at Victoria University. Understanding the systems engineering issues will be critical to developing cost-effective processes, along with management strategies for wetting and scaling phenomena. These will be determined by the particular application. For instance, treatment of hot blow-down water in industrial applications will have scaling issues, while energy recovery and efficiency is more important for seawater desalination applications. The configuration of membrane distillation units in these various applications will differ significantly, reflecting the importance of high energy efficiency against reduced capital cost and large waste heat availability. EN Dry-Cooled Tower Technology By John Harten, CS Energy The team at CS Energy’s Kogan Creek Power Station is gearing up for the first year of operation, following the official opening of the project by the Queensland Premier Anna Bligh in December 2007. After a 3-year construction period, the 750 MW power station and adjacent coal mine are complete. As Australia‘s largest single generating unit, the Kogan Creek power station, situated near Chinchilla in southwest Queensland, is meeting Australia‘s growing demand for energy, without adding to pressure on scarce water resources in the Western Downs region of Queensland. Kogan Creek Power Station The power plant uses 90% less water than a conventional wetcooled power station, through the application of dry cooling technology and water management practices. The design was based on Siemens Varioplant Steam Power Plant concept. The dry cooling technology is used in the air-cooled condenser section of the plant, which cools and condenses the heated steam after it has left the turbine. The air-cooled condenser works ‘like a giant car radiator’, but instead of the air cooling hot water in tubes it cools steam. The air-cooled condenser at Kogan Creek consists of 48 fans, each with a nine metre diameter, that induce a breeze to flow air over finned tubes containing hot steam. The tubes have fins attached to provide a large surface to dissipate the heat from the steam flowing through them. The fans basically cool and condense the steam back into water so it can be used again in the boiler. Because Kogan Creek uses an air-cooled condenser, water is only required on site for the boiler, domestic use and for cooling machinery, and this water is sourced from local bores. Kogan Creek is only the second power station in Queensland with an air-cooled condenser (InterGen’s Milmerran Power Station was the first) but the technology is widespread internationally, where it is used in South Africa, Iran, Europe and the United States. 14 EnergyNews — Volume 26 No. 1 March 2008 Air-cooled condenser fans up close Kogan Creek is a ‘mine mouth’ power station, where coal is taken directly from the mine pit, transported to the power station and burnt in the boilers. The mine delivers up to 8,000 tonnes of coal each day via a 4-kilometre overland conveyor. The boiler and ancillary plant have been specially designed to handle unwashed coal, which contains about 28% ash, mainly rock and dirt. Not washing the coal conserves the limited water resources of the region and contributes to the economics of the power station. Kogan Creek is also highly energy efficient, thanks to the supercritical design of the boiler, which uses a more efficient process for transfer of the energy from the burning coal to the water to produce the steam that drives the turbine and generator. As a result, Kogan Creek’s combustion is 3–4% more efficient than the subcritical coal-fired plants that comprise most of the plant running in Australia. In terms of greenhouse gas intensity, Kogan Creek Power Station will have one of the lowest environmental emissions per GWh of any coal-fired power station in Australia. It also has specialised equipment to continuously monitor emissions and super-efficient filter technology to reduce particle emissions to state-of-the art dust levels. EN Water in Brown Coal: Blessing or curse? By David Allardice, FAIE Since a Victorian Government Royal Commission in 1891, it has been recognised that the moisture content of Victorian brown coals is a major obstacle to their effective utilisation. This is equally true today, with the added concern that evaporating this water in a conventional power station increases the CO 2 emissions per MWh of electricity generated by at least 25%. However, with Victoria’s water supply problems during our extended drought, the question has been raised as to whether the water in the coal should now be regarded as an asset, to be maximised by selecting higher-moisture brown coal fields for future development. Current Latrobe Valley power stations dry the coal before combustion in an integrated milling drying circuit, using hot flue gas recycled from the furnace. The evaporated moisture passes through the furnace and boiler and up the stack. The energy to dry the coal cannot be recovered in these systems. In such power stations, additional water is consumed in the steam cycle to condense the steam exiting the turbine before returning the condensate to the boiler. This water demand, typically 2 tonnes per MWh is far more than the total moisture in the coal consumed. For many years, local brown coal research has aimed at developing more efficient drying and dewatering processes. Before global warming became a concern, these developments focussed on reducing costs and improving resource utilisation by reducing coal consumption. However, they now have the added benefit of reducing the CO2 emissions by requiring less energy to dry or dewater the coal. Dewatering processes by definition extract the water in liquid form saving the latent heat that would have been required to evaporate the moisture. Dewatering processes that involve heating the brown coal before extracting the water produce a water effluent contaminated with dissolved salts from the coal and dissolved organic compounds such as phenols from its thermal decomposition. Generally, the higher the dewatering temperature, the greater the contamination. The contaminated water requires substantial treatment before it can be used or disposed of. An example is Hydrothermal Dewatering (HTD) that evolved as a slurry version of the Evans-Siemon dewatering process, developed by AIE Members David Evans and Stan Siemon at University of Melbourne in the 1970s. HTD heats a brown coal slurry to 280–300ºC at pressures that prevent evaporation. HTD in effect accelerates the coalification process, increasing the apparent rank of the coal. Typically, 66% of the moisture in Latrobe Valley brown coals can be separated in liquid form. However, the high cost of the water treatment has been a major disincentive to its commercialisation although there are new variants of HTD still under development. Another brown coal dewatering process is the Mechanical Thermal Expression (MTE). This process is currently being piloted at a 15 tonnes per hour scale at Loy Yang in a project initiated by the CRC for Clean Power from Lignite. A coal water slurry is heated to 150–200ºC and the water squeezed out with a hydraulic press. MTE typically removes 75% of the water in Latrobe Valley coals. Because of the lower temperature, the recovered water is less contaminated than from HTD, but still requires extensive clean up before re-use. Some evaporative drying processes can also recover the coal moisture in liquid form. Steam Fluidised Bed Drying (SFBD) evaporates the moisture from brown coal in a steam fluidised bed operating at 100–110ºC and close to atmospheric pressure. The energy used to evaporate the moisture can be substantially recovered using vapour recompression to heat the fluid bed and condense the evaporated moisture. This process can dry the coal to 10–12% moisture, removing more than 90% of the moisture in the brown coal in a single step and producing a water condensate suitable for industrial use after minor treatment. Loy Yang A and B power stations and their associated brown coal mine The SFBD process was developed from the original concept of Prof Potter at Monash University around 1980 and further improved by German technologists — the German acronym for the process is WTA. Demonstration plants in the 1990s in Germany and at Loy Yang led to an improved ‘fine grain’ version of WTA. A 110 tonnes per hour commercial fine grain plant is under construction by RWE at its Niederaussem brown coal power station near Cologne. Fine grain SFBD/WTA is the proposed drying technology for the Monash Energy project in the Latrobe Valley and the International Power demonstration retrofit project at Hazelwood Power Station. A Japanese consortium, NBCL, also piloted an evaporative drying process for a coal oil slurry at its Morwell coal-to-oil pilot plant in the 1980s. This process also achieved energy and water recovery by vapour recompression. A 600 tonnes per day low rank coal drying and briquetting plant using this drying technology is under construction in Indonesia. Climate change concerns have also accelerated efforts to develop more efficient brown coal power generation systems that use less coal, emit less CO 2 and reduce the water consumption in the plant. The leading contender locally is the HRL Integrated Drying Gasification Combined Cycle (IDGCC) EnergyNews — Volume 26 No. 1 March 2008 15 power generation process, which reduces CO2 emissions by 30%, water consumption by 50% and generation costs by 30%, relative to current brown coal power stations. Planning for a 400 MW commercial IDGCC demonstration plant is well advanced. IDGCC can also recover some of the moisture in the coal by condensing the vapour from a pre-drying step to preheat the coal. However, the major water saving from IDGCC is through its improved efficiency and the high proportion of its generation from the gas turbine cycle which, unlike the steam cycle, does not require cooling water. In summary, there are technologies available or under development to recover the moisture from brown coal, but the motivation is generally to increase the overall process efficiency and reduce the CO2 emissions. As a byproduct from achieving CO2 savings, the recovered moisture can provide a useful contribution to the process water demand of brown coal plants but is unlikely to produce surplus water for external use. The cost of the drying/dewatering plant and the subsequent water treatment plant to clean it, make it expensive water. It is therefore difficult to see an economic justification for selecting a higher moisture coal, requiring a larger drying and water treatment plant, in preference to a lower moisture coal of similar quality. EN Meter Data Collection Trends in Australia By Paul Nelsen, Managing Director, Itron Inc Driven by a need to enhance conservation efforts, achieve operational efficiencies, increase revenues and improve meter data accuracy and customer service, many utilities throughout Australia and New Zealand are turning to advanced meter data collection and management technologies to improve the utility landscape. Automatic Meter Reading (AMR) technologies help electric, gas and water utilities collect monthly billing data from meters remotely and automatically. Several different communications media can be used to transmit data seamlessly, including wireless, power line carrier and telephone. Additionally, utilities are provided lowered meter reading costs, increased read accuracy and reduced cost through these automated technologies. The world’s energy and water resources are being challenged by population growth and climate change. Utilities must responsibly manage natural resources in ways that guarantee their commitment to deliver reliable service to customers. Conservation programs are imperative in meeting the needs of their communities during peak usage periods. The Australian electricity market is pioneering the move to full Advanced Metering Initiative (AMI) rollout. When interval meter reads are combined with innovative software solutions, utilities can analyse usage, identify and manage peak load, forecast usage more accurately, and design programs, based on detailed customer profiling and data logging, that encourage responsible energy and water consumption through demand response tariffs. For example, the implementation of Itron’s AMR solutions make it possible for authorities to gather data more frequently and efficiently, saving substantial time and money while improving customer service and increasing revenue certainty. With the arrival of technologies, such as walk-by radio frequency data collection for water, and the move towards even more open architecture, today’s Australian utilities are leading the move to more efficient systems. EN Marine Power: Waves, tides & currents By Andrew Taylor, Project Engineer, AMOG Consulting Wave and tidal energy are increasing slotted into publiclyespoused lists of the coming renewable energy mix, but this industry is yet to make a big splash commercially. While firms like AMOG are seeing increased business providing specialist engineering analysis to marine energy device developers from around the world, the field is at best just into the early stages of commercialisation. Similarly to other renewables — but perhaps a step or two behind — there is significant potential, a long history of interest and a very recent giddy-up coming from the shifting political mood in response to climate change. Going forward from the existing tiny base, wave and marine current energy devices will be contributing an increasing amount to the world energy mix. This will most likely continue to be led by significant government encouragement in places such as Portugal and the United Kingdom, where long-term targets as high as 20% are being seriously suggested. 16 EnergyNews — Volume 26 No. 1 March 2008 Ocean movements as an energy resource The global ocean covers over 70% of the earth’s surface and it is continually in motion. Visitors to coastal locations across the ages have been in awe at the power of these movements — just think of south-west Tasmania or the ‘Horizontal Falls’ off the Kimberly coast. The patterns and magnitudes of the marine energy resource differ widely from place to place. On foreseeable human time scales, these motions are essentially exploitable forever without diminishment and are naturally considered in the category of renewable. The ocean’s kinematics are composed of quite different types of motion, which when targeted for energy conversion lead to very different technologies. Waves, tides and currents are the broad categories considered here. Surface waves in the ocean are generated by the action of atmospheric winds, which are in turn ultimately driven by the distribution of solar warming across the globe. Such north-west of Australia have attracted interest over the years — recall Senator Wilson Tuckey’s public promotion of Western Australian tidal power’s potential for export. However, the magnitude of the available resource is obviously not the only, or even the prime, consideration in developing energy extraction businesses. Availability and survivability Pelamis P-750 Wave Energy Converter in action (Image copyright of PWP Ltd) waves do not only act to accumulate and store energy from the wind but can carry this energy over thousands of kilometres to be eventually pounded against the coast. Wave energy has long been recognised as having one of the highest power densities available among all the exploitable renewable energy resources, and has the additional advantage that energy levels can be predicted several days ahead. Like the wind resource, different locations are more or less naturally endowed, with geophysical features such as distant wind patterns and geography contributing to the local occurrence of big regular swells. It is no surprise that the surfing community also has a special interest in such coastal locations and at least one instance has led to a campaign against a wave energy installation on the basis of potentially disturbing the quality of the surf. Although the oceanic tides can be considered as long period waves, tidal motions differ fundamentally from wind waves as they are ultimately driven by gravitational attraction and the relative movements of the earth, moon, sun and planets. The pattern and magnitudes of the tides is a surprisingly complex topic and local geographic features play a big role. The rise and fall of the tide is very predictable at any one site and the broadly diurnal or semidiurnal period is manifest in the form of oscillating low head differentials and direction swapping marine currents. Another source of predictable marine currents are the thermally-driven ocean circulations that lead to well known unidirectional flows such as the Gulf Stream or the Kuroshio Current. There is some obvious technology overlap between devices that exploit marine currents and tidal flows. The huge tidal movements in the CETO II deployment, February 2008 (Image copyright of Carnegie Corporation Ltd) Ocean waves, tides and currents are variable energy sources manifest as natural fluid motions in the earth’s system. The pattern of energy availability in any one location differs temporally from other sources such as wind and solar, which is a significant consideration for distributed electricity generation applications with regard to scheduling diversification. However, with energy availability too much of a good thing is a particularly major problem for marine energy devices. That same energy density that is so promising for exploitation is what renders the cruel sea such a challenging place for engineering. Looking back over the track record of trial installations, it is almost embarrassing how many have been destroyed by underpredicted waves, currents or the like. Subsequently device ‘survivability’ is a key characteristic promoted by developers. Markets It almost goes without saying that the regulatory and commercial environment for large-scale energy technologies is now changing to the advantage of wave and tidal applications, particularly with respect to greenhouse gas emissions. Similar to wind, distributed electricity generation sites at the scale of tens of megawatts is the primary end use for wave and tidal plant in the immediate future. Direct powering of desalination processes is however a very real alternative application and most developers promote this possibility for their devices. Of course, future market development may also see hydrogen production or other end uses evolve. Technology The most telling feature of the current state of wave and marine current power devices is the general lack of technological maturity. There is no comparison to the wind industry’s three-bladed horizontal access turbine, which for better or worse is now the ‘normal’ way to capture wind energy on a large scale. A plethora of ocean device hopefuls and start-ups are only at the stage of scaled prototype testing. There is a wide range of wave and marine current devices being pursued, with some field leaders but no clear winners. On the other hand, some large commercial installations do exist and plenty are already applying for planning permits both in Australia and overseas. Investor confidence is at present relatively low and government incentives are playing a large role. Note that other marine renewables such as OTEC or offshore wind are not discussed here. Some readers will be aware of the significant legacy of ocean engineering developed within the traditional offshore industries — moorings, compliant floating structures, subsea cables, marine growth and corrosion are known factors. This ready-made economy of ancillary equipment, expertise, codes and standards has meant that the wave and EnergyNews — Volume 26 No. 1 March 2008 17 tidal technologies are not starting from scratch. Similar affinities also exist with aspects of the wind and hydro sectors. Interested readers are encouraged to refer to the following websites: www.rise.org.au/info/Tech/ www.emec.org.uk/ www.oceanrenewable.com/ The bottom mounted CETO device being developed by Carnegie Corporation has received some press, with developmental trials at Freemantle. Seemingly a little less progressed commercially, Biopower Systems was recently awarded a A$5 million Renewable Energy Development Initiative grant from AusIndustry to further develop and test their ‘biomimitic’ wave and current devices. www.carbontrust.co.uk/technology/ technologyaccelerator/marine_energy www.pelamiswave.com www.oceanlinx.com www.carnegiecorp.com.au/ www.biopowersystems.com Here, we categorise the serious candidates as being either ‘wave’ or ‘marine current’ devices, that are to be installed either ‘onshore’, ‘near shore’ (10–25 metres depth) or ‘off shore’ (> 30 metres depth). Modularity is an almost universal approach amongst developers, allowing ‘farms’ of repeated units. Also fairly common is piggybacking onto existing installations such as breakwaters. As per the experience of the hydro sector, there are a range of extraction concepts that are no longer acceptable although technically possible. A case in point are large tidal barrages such as the over 200 MW plant installed in the 1960s at La Ranch. In general, it is these factors beyond the nuts and bolts of the device that play a huge role in determining the viability of a technology. A detailed but high-level triple bottom line evaluation across the lifecycle of a generic device suggests that of all the categories listed above, offshore wave devices are the most preferable general option, though local details and opportunities seem set to result a variety of installations. Australia All of the existing installations in Australia are essentially prototypes. Oscillation Water Column device developers Oceanlinx (previously Energetec) have been in the news with their prototype at Port Kembla in NSW, and claim to be in ‘advance permitting stages’ for a proposed 27 MW floating installation at Portland, Victoria. Oceanlinx device – one-third scale (Image copyright of Finsbury Ltd) 18 EnergyNews — Volume 26 No. 1 March 2008 Proposed commercial CETO array (Image copyright of Carnegie Corporation Ltd) A much publicised but failed tidal proposal was the planned large tidal barrage near Derby in Western Australia. It made the news in the late 1990s but was rejected on environmental grounds. Overseas Various governments around the world have begun incentive programs directly aimed at maturing marine energy technology. Notable examples include the United Kingdom Carbon Trust’s Marine Energy Accelerator program, the European Marine Energy Centre and the English ‘Wave Hub’. The ‘wave hub’ large-scale test facility has a small list of participating technologies. A 2 MW wave farm of floating Pelamis devices was launched in 2006 off Portugual helped along by the generous feed-in tariffs offered for renewable energy in that country. A quick web search will turn up news of myriad planning applications and trials from the United States to Korea. While the runs are not yet on the board for installed capacity, the next few years will see quite some change. EN Artist’s impression of a Pelamis wave farm (Image copyright of PWP Ltd) Articles Australian Energy ABARE’s national and state projections to 2029–30 In December 2007, ABARE (Australian Bureau of Agricultural and Resource Economics) released its latest medium to long-term projections of Australian energy consumption, production and trade. The analysis covers the period from 2005–06 to 2029–30, with a focus on the medium term to 2011–12. The projections are prepared using data from ABARE’s surveys of energy usage, its projections of commodity markets and its E4cast model, which was modified in 2007 to include representation of solar electricity generation. The projections incorporate those policies that have been implemented at the date of publication; policies announced but not implemented are excluded. Therefore, the Australian Government’s plan to introduce an emissions trading scheme and increase the Mandatory Renewable Energy Target (MRET) to 20% of electricity supply by 2020 have not been included. Further, the projections do not include the impact of climate change on economic growth. These projections can be thought of as the ‘business-as-usual’ outlook. Key policy measures modelled explicitly are: the Australian Government’s MRET scheme; the NSW Government’s greenhouse gas abatement scheme; the Queensland Government’s gas scheme; and the Victorian Government’s renewable energy target scheme. The MRET scheme requires the annual generation of renewable electricity to increase by 9500 GWh from 2000 to 2010. Interim targets have been set (commencing at 300 GWh in 2000) to ensure that there will be consistent progress toward achieving the additional 9500 GWh of renewable energy by 2010. It is assumed that this target is maintained until 2020. In E4cast, the renewable energy target is modelled as a constraint on electricity generation. However, this requirement for renewable electricity generation is reduced to account for renewable technologies that are not explicitly modelled, such as solar water heaters. It is assumed that about 23% of the MRET target will be met by technologies that are not explicitly modelled in E4cast. Energy consumption Australia’s primary energy consumption is projected to grow at an average rate of 2.2% per year, from 5,688 petajoules (PJ) in 2005–06 to 6,479 PJ in 2011–12. Over the full outlook period to 2029–30, primary energy consumption is projected to grow at an average rate of 1.6%, reaching 8,298 PJ. Although energy intensity is projected to continue to decline at around 1% per year, energy consumption per person is projected to rise over the outlook period from 275 gigajoules (GJ) in 2005–06 to 324 GJ in 2029-30. This represents the net outcome of countervailing upward and downward pressures on energy consumption growth in the medium term. Upward pressures include the relatively strong assumed rate of GDP growth of 3.0%, and a continuing strong demand for energy by energy-intensive industries such as nonferrous metals. Downward pressures on future primary energy consumption include relatively high oil prices, government policies and improvements in energy efficiency. The average annual rate of end use energy efficiency improvement is assumed to be 0.5% over the projection period for all fuels in non energy-intensive sectors. In sectors containing energy-intensive industries, the low capital stock turnover relative to other sectors is expected to result in a lower rate of energy efficiency improvement of 0.2%. The rate of energy efficiency improvement is also assumed to be different in regions or sectors where greenhouse gas abatement policies are in place. For example, the NSW Government’s greenhouse gas abatement scheme is expected to accelerate the rate of efficiency improvement in the use of electricity in that state, and a higher rate of energy efficiency improvement (0.7% per year) is assumed. The E 4cast model also incorporates energy efficiency improvements in the electricity generation sector, reflecting expected technological developments over time. Thermal efficiency improvement rates are determined exogenously according to the maturity and capacity expansion rates of the electricity generation technologies modelled. The electricity generation module of the model allows for peak and offpeak generation, and includes 18 generation technologies including for the first time, photovoltaic electricity generation technology, but not domestic photovoltaic panels nor planned expansions to photovoltaic generation capacity, such as the 154 MW Solar Systems plant planned for Victoria. The future use of new generation technologies that are not currently used in Australia is based on the investment cost of each technology relative to those currently in use and future cost assumptions. Though the model includes four technologies that incorporate carbon capture and storage (CCS) technologies, in the absence of an emissions trading scheme, CCS is not expected to be used commercially over the projection period because of its relatively high cost. Primary energy consumption in Australia, by fuel Coal’s share of primary energy consumption is projected to decline from 41% to 35%, for the most part replaced by gas (increase from 19% to 24%) and renewables (6% by 2029–30). EnergyNews — Volume 26 No. 1 March 2008 19 Sector projections Energy consumption in Australia’s transport sector The mining sector’s share of final energy consumption is projected to increase from 6.7% in 2005–06 to 12.5% in 2029–30, overtaking the commercial/services and residential sectors. This reflects the large number of energy-intensive project developments that are assumed to take place over the projection period. The basic nonferrous metal industries, including alumina, are the major consumers of gas at the end use stage. In total, the growth in basic nonferrous metal energy consumption is expected to account for around 47% of the projected increase in manufacturing sector energy consumption between 2005–06 and 2029–30 (table 16). The transport sector remains the largest energy-consuming sector — 35.8% in 2029–30 (down from 39.1% in 2005–06). Road transport is the largest energy consuming component of the transport sector, and passenger motor vehicles were the largest energy consuming sector within road transport. Energy use in the road transport sector is projected to grow by 0.9% per year over the projection period. This growth is driven by energy use in road freight. However, consumption of petrol is projected to increase modestly (0.1% per year), because car ownership in Australia is reaching saturation level as per capita income increases.

What do Cate Blanchett, Brad Pitt, Placido Domingo and your editor have in common? … They are among the few people around the world to take a ride in the BMW Hydrogen 7. The BMW Hydrogen 7 looks and feels like the 760 series 260 HP luxury sedan it is. Its special features are subtly hidden among the clean external lines and the comfortable interior. Unlike other hydrogen cars available today, it has no fuel cells – just a familiar (but new-fashioned) combustion engine; one that can burn either petrol or hydrogen, which is a big advantage that only the combustion engine can provide. “Hydrogen infrastructure buildup is one of the biggest issues in developing hydrogen vehicles and a hydrogen economy,” said BMW Group’s Clean Energy Project Manager, Willibald Prestl. “During that phase, combustion engine-driven vehicles provide much more flexibility for the user being able to use both existing conventional infrastructure and oncoming hydrogen infrastructure.” Granted the liquid hydrogen we used to refill was produced from natural gas in China, but the BMW Hydrogen 7 was created with a ‘solar hydrogen’ future in mind. “BMW is the only developer using liquid hydrogen, and we are now the leaders in cryogenic know-how,” said Mr Prestl. “Other hydrogen vehicles use a compressed hydrogen system — a technology that is easier to develop but gets only half the energy for the same volume of fuel.” The BMW Hydrogen 7 has range of 200 kilometres on hydrogen and a further 500 kilometres on petrol. The idea is to commute around town (where emissions quality is more important) using hydrogen and emitting only steam, and use petrol for long-distance trips where initially hydrogen will not be available. The changeover is achieved with the push of a button on the steering wheel. “Another advantage of the combustion engine is that it is a very robust und well-known technology, and all infrastructure for producing combustion engines is already in place,” said Mr Prestl. 20 EnergyNews — Volume 26 No. 1 March 2008 BMW Hydrogen 7 at Federation Square, Melbourne (note the 2 fill points) The key enabling technologies are the fuel management system and the liquid hydrogen fuel system. To get the fuel: air mix right requires a very detailed understanding of how hydrogen burns, and there is a lot of know-how in the engine management system. “It is seamless to the driver, but it involved a lot of technical development,” said Mr Prestl. “And, a lot of development went into the additional hydrogen fuel system. Hydrogen has a very low energy density at ambient temperature and pressure. You can either compress it (up to 700 Bar) — but that’s a lot of pressure to handle — or you can use relatively low pressure (up to 5 Bar) and cool it down until it liquefies (minus 253°C).” “We have engineered a dispensing system and, in partnership with major oil companies, we are putting hydrogen refuelling facilities on service stations,” said Mr Schlüter. “It is not so much of a technical challenge to deliver the hydrogen to service stations but it is very expensive. In a hydrogen future, delivery will be by pipeline or truck.” In the BMW Hydrogen 7, the tank cools as the cold liquid hydrogen is pumped in, and it stays cold because it is highly insulated with space technology materials. “It will take some generations of vehicles to get the cost of these materials down enough for the car to be commercial,” said Mr Prestl. The other issue that might be on some people’s minds is safety, but it turns out that liquid hydrogen is no more dangerous than petrol, if handled correctly. In fact, it has some safety advantages. “It is very light and dissipates quickly,” said Mr Prestl. “If there is a leak or a rupture (something we have not been able to do to the tank because it is so strong) it would go straight up. Also, hydrogen does not radiate heat so much when it burns. In tests that involved relieving and burning the whole contents of a tank via an outlet in the roof, the interior of the car was undamaged. The main issue is that it is odourless, so if it did leak you would not smell it. So, we have developed special sensors with our partners and a hydrogen warning system for the unlikely event of any leakage.” BMW has produced 100 vehicles and placed them with ‘ambassadors’ to demonstrate the technology. “It is a production car, but not a commercially-viable one,” said Mr Prestl. “It will take a couple of generations to be affordable. Unlike concept cars, anyone can drive it and together our ambassadors have driven two million kilometres with no major problems.” To do this, they have needed refuelling facilities. The Linde Group is the exclusive partner for BMW’s hydrogen events around the world, and brought the refuelling equipment from Germany. “The refuelling system presented special challenges,” said Thomas Schlüter of Linde Group’s Hydrogen Solutions. “Challenges with the coupling and the storage containers themselves.” There are now more than 60 hydrogen refuelling stations around the world, of which six are liquid hydrogen sites, all in Europe or the United States. Willibald Prestl refuelling at Linde Group’s temporary Melbourne facility Your editor can vouch for how easy it was to press a button on the dash to open the fill point cover; attach the (somewhat heavier) liquid hydrogen hose; and fill the tank. It is a closed coupling that cannot disconnect while filling, and, there is an initial pressure test with nitrogen. The ‘user-friendly’ coupling was developed in partnership with Honda and General Motors. The plan is to develop one international standard (rather than the 200 different petrol filling systems around the world). BMW plans to develop a storage system that combines high pressure and cryogenic temperatures as a new breakthrough hydrogen technology “We would like to get some new synergies and eliminate the disadvantages of both systems,” said Mr Prestl. It’s now too late for readers to get a ride in the BMW Hydrogen 7 in Australia. The car and its refuelling system are headed for the Beijing Olympics. EN EnergyNews — Volume 26 No. 1 March 2008 21 Book Review Lights Out The electricity crisis, the global economy and what it means to you, by Jason Makansi, John Wiley and Sons Australia Ltd, RRP A$41.95 (inc. GST) Not since Arthur Hailey ’s gripping 1978 novel Overload have I read a more riveting book about the electricity industry and its stakeholders. The difference between the two is that the former is fiction and had a thrilling (but happy) ending, and much of the latter is fact and the end-game may well be less inviting. Lights Out paints a picture of the United States’ electricity industry on the point of collapse, but importantly it also sets out a pathway to salvation — if only the industry and consumers are prepared to grasp a savvy, intelligent, new future. The book is in three parts and opens with the worst case scenario of ‘lights out’ mostly due to failing network infrastructure and, in particular, the dysfunctional poorly interconnected ‘third-world’ transmission systems under constant strain to ‘wheel’ power according to the rules of economic engineering rather than sustainable electrical practices backed by sound infrastructure investment. At work are the triple forces of deregulation, market-oriented institutions and globalisation. Vulnerability is identified in six key areas: deteriorating transmission grids, lengthening fuel supply lines, lack of storage and standby back-up power, lack of specialised workers to operate and maintain the infrastructure, the interconnection of the grid from a national security perspective and environmental impacts. The first part of the book also has a brief, easy-to-read and informative history of electricity supply and its changing regulatory and commercial environments in the United States under fun headings such as: Downing Street — The seeds of privatisation are sown, Wall Street – Where investment flows, and The Dark Street – Where electricity does not flow. This part of the book is however far from totally negative and offers glimpses, developed further in later chapters, on how to prevent the worst case from happening by fixing up transmission, limiting markets to where they work, building back-up (storage) capacity, empowering consumers instead of making them feel guilty, and acknowledging the need for bulk central generation, in particular, nuclear and coal. Part two of the book greatly expands on the insecurities, vulnerabilities and the uneasy state of the industry. Of particular global interest is the short chapter on ‘living with a transaction economy’ with its ever-increasing speed and diversity of endless transactions (and fee taking at every point), almost for the sake of it. “Assets are no longer the focal point of a valuable company anymore. The balance 22 EnergyNews — Volume 26 No. 1 March 2008 sheet is.” In the past, “… engineers gold-plated the system by adding layers of cost that were borne by consumers … today, financial engineering is stripping away that gold-plating and trading it back and forth to keep extracting profits at the margins”. Part three is aptly titled Fighting the last war, planning the next one. Makansi describes the last war as the need to come to grips with rapidly escalating electricity prices potentially undermining the United States’ economy; escalating prices due to expensive fuels such as LNG and natural gas, a poor regulatory regime that discourages investment, and the creation of markets that simply do not work. He sees the next war as the need to find real solutions with the industry “on the precipice of a new construction cycle for coal or nuclear plants” but without “the industry and its regulators having long-term solutions for high-level nuclear wastes or carbon dioxide discharges”. Part three does offer the potential for that elusive industry salvation by setting out long-term solutions for electricity storage, coal and extracting its full value, exercising the nuclear options, empowering consumers, distributed power and redefining the grid as an intelligent one. Makansi concludes with a vision of the future that is built on shifting government funding to networks and energy services (including the really smart versions of smart meters); creating the right investment environment for advanced nuclear and coal plants, energy storage systems, renewables and distributed power systems; full deregulation of the wholesale market; deregulation of the retail market but with built-in safeguards; minimising financial engineering; securing fuel and component supply lines; and, above all, “make electricity visible, understandable and part of our every day discourse”. Lights Out is clearly an important, insightful book, written by an author who knows how to communicate a complex subject in bite-sized pieces that are informative and fun to read. The fact that it is written largely from an American perspective, with all that nation’s complexities and excesses, should not deter Australian readers wanting to understand what the electricity game is all about. For Australian industry experts, the book is a must, if only for Australia to avoid facing a similar nightmare. Dr Harry Schaap Dr Schaap is an Australian electricity industry expert with wide experience in research and development, environmental management, demand side management, consulting and climate change. Letter to the Editor Editor, RE: Having fun with the future on page 69 of September 2007 issue of EnergyNews I am well aware that Sweden has an approach to generating biofuels that differs markedly from that most other countries are aspiring to. They will not, in the first instance, be using food for fuel as in America and Brazil but timber grown in places unsuited to growing food. Nevertheless, SAAB is trying to sell its ‘BioPowered’ cars into food-fuelled markets and that is just as reprehensible as growing the fuel — indeed more so, since they are helping to create the demand for such food-based fuel. (driver only driver owned) car-based commuting. Engine efficiency is roughly 15% and a driver weighs one-fifteenth of the vehicle’s weight, so most of the energy in the fuel goes to move the car rather than the driver and we’re down to about 1% efficient. Then there is all the energy required to make the car, transport it to its owner, maintain it during its life and then recycle its materials once its life is over. So we’re down to about 0.5% efficient? It may be the case that Brazil’s sugar cane-based (and Sweden’s wood-based) ethanol delivers energy at the bowser greater than the total anthropogenic input required to deliver it there, but America’s corn-based ethanol doesn’t (see National Geographic, October 2007, as well as “Thirsty biofuels threaten to take food off menu” on page 25 of The Australian of 12 October 2007 and “Fuel for Thought: Ethanol presents a dilemma to ethical motorists” on pages 221–222 of the October 2007 Qantas inflight magazine). This calculation of a car’s efficiency says nothing about making good the damage caused by the greenhouse contribution it makes; the damage caused by the toxic gases and particulates it releases; or the damage caused by the heat it raises (urban heat islands). Nor does it provide for, maintain and pay for the environmental costs of its infrastructure; nor of making good (if that’s at all possible) the deaths and injuries caused directly on roads and indirectly on the ‘battlefields of oil’. And still people fiddle with changes to engine and fuel efficiency, playing around with a few tenths of that 0.5% when putting a second person into the car and simply cutting engine size could double its efficiency. In the light of this, endangering food supplies and the planet’s fertility is madness. The contradictions in driving a food-fuelled car are not only matters of ethics. Of particular concern are the gross inefficiencies that would not be countenanced elsewhere. All automobile fuel and engine design changes run up against the implacable reality of the catastrophic inefficiency of DODO Best regards, Frank Fisher, FAIE Adj Prof, Swinburne University/Assoc Prof, Monash University (Inaugural) National Environmental Educator of the Year National Energy Essay Competition The AIE is proud to support the national essay competition addressing the long-term future possibilities for primary sources of electrical energy in Australia. Institute President, Murray Meaton, will be one of the judges, and we encourage all young energy professionals to participate. The activity aims to energise the young to study Australia’s energy future — their energy future — and to introduce a rigorous and disciplined level of information into the public arena to improve the quality of the debate regarding the next phase of primary sources of energy for the production of electrical power to the east and west principal Australian integrated electrical networks (“the grids”). The competition is open to Australian citizens and permanent residents under 31 years of age as at 30 June 2008. There is a cash prize pool of $91,000, providing for four prizes each of $20,000, and one prize of $1,000 to an entry submitted by a person(s) under 22 years old, awarded by a Judging Panel, and an additional prize of $10,000 awarded to the entry chosen from amongst the winners by the interested public. Entrants can be individuals or teams of up to three members (all must meet the entry requirements). The essay is to consist of parts A and B. Part A will address the primary energy sources for electricity generation for the period 2010 to 2050, considering economic, environmental and societal impacts within a sustainability framework; coal, gas, hydro, nuclear, solar, wind, geothermal and other renewables; whole-of-life perspective; and the changing needs of society and industry resulting from technology commercialisation. Part B will postulate the prospective energy sources for the 50 years beyond 2050, considering a longer-term view of energy sources in the light of promising research developments. The competition opens on 31 March 2008 and closes at 5 pm on 30 June 2008.

For Melbourne Branch events, see https://pams. com.au/aie Young Energy Professionals Melbourne YEP’s Inaugural Event AIE Melbourne Branch hosted its first meeting for young energy professionals on 15 November 2007. Here, branch YEP representative Mike Bagot reports. The first in our YEP seminar series was held at the offices of the Victorian Department of Innovation, Industry and Regional Development, and attracted 22 young postgraduates and employees. We were fortunate to have Jeff Cochrane, CEO, Monash Energy, to present an overview of his career path and to lead a discussion of the factors necessary for successful navigation through the ‘reefs’ of early employment. First, Jeff spoke on the possible future trends in the global energy market based on political, economic, environmental and social considerations, with specific emphasis on Australia. He noted that the path he has trodden in his professional life is a very different one to what we are likely to follow. Jeff also gave us a brief update on the lignite gasification plant proposed for the LaTrobe Valley, including details of the planned sequestration and storage technology. This generated a lot of interest from the audience. Most attendees stayed on after the seminar to socialise and enjoy the refreshments provided. I was impressed by the level of enthusiasm and interest circulating through the room. There is, without doubt, a vibrant group of young people entering the energy sector. Most of the jobs we will be doing in our careers have not been created yet, but now we need to network and build relationships with contemporaries. This is the foundation of the Melbourne YEP group. EnergyNews — Volume 26 No. 1 March 2008 25 Study Scholarship Report Nick Florin was awarded the first Australian Institute of Energy and Energy Council of Australia joint study scholarship in 2006. In May 2007, he took the opportunity to travel to Europe and Japan on a study tour. This is his brief tour report. The study tour timed perfectly with the final months of my PhD research (just submitted early 2008). My project investigated hydrogen production from biomass via a thermochemical conversion process. For the process, I developed a CO2 sorbent that captures carbon emissions in biomass gasifiers resulting in an enhanced hydrogen yield. This work was carried out in the School of Chemical and Biomolecular Engineering at The University of Sydney. My first stop was Germany, where I presented my research at the 15th European Biomass Conference in Berlin. This was the world’s largest general meeting in this field. Hot topics in Berlin included: lignocellulosic ethanol, and the concept of a mobile biorefinerey. Making the biomass refinery mobile eliminates the energy penalties associated with transporting bulk biomass feedstock. I was inspired, learning a lot about exciting cutting-edge research in my field and receiving valuable feedback for my own work. After the conference, I visited the Department of Decentralised Energy Conversion at the University of Stuttgart. There, experimental research is on a large scale, with a power station on the campus providing heating and electricity for the university. It was clear to me that Sydney University could do well with a large-scale biomass gasifier for organic campus wastes. University of Stuttgart power station After travelling through Germany and France I left continental Europe and continued my study tour in the United Kingdom. While in London I visited a novel carbonneutral housing initiative called Beddington Zero Energy Development (BedZED). As well as incorporating a range of environmentally sustainable design features like ‘green roofs’, the development has a combined-heat-and-power plant which uses wastes from a local tree surgery operation. The electricity and heat generated is distributed on site. I also spent a few days in Cambridge where I visited the Department of Chemical Engineering and discussed issues relevant to scaling up the process we have developed at Sydney University. On my way home I made a stopover in Japan, where I visited two research groups and presented my research. I was particularly fortunate to tour the facilities of the Japanese National Institute of Advanced Industrial Science and Technology. I also visited academics at the Tokyo Metropolitan University, and participated in a seminar series. It was a great opportunity to see how research is conducted in world-class laboratories and have discussions with leading scientists face-to-face. Nick cycling to the conference in Berlin 26 EnergyNews — Volume 26 No. 1 March 2008 Overall, I had an awesome time! As a young energy professional (YEP), I know the experience benefited my early career, and I am very grateful to the Institute and Council for the opportunity. I strongly recommend all YEPs apply this year. [Applications close 3 April; see notice on page 99 of December 2007 issue of ENERGYNEWS, ed.]. Hydrogen Matters Federal Government Review of Hydrogen Energy Technology Last September the (then) Commonwealth Department of Industry, Tourism and Resources (now Department of Resources, Energy and Tourism) commissioned the Wyld Group to develop a Hydrogen Technology Roadmap for Australia. The roadmap will be completed in April 2008 and the outcome will be presented at the 17th World Hydrogen Energy Conference in June (WHEC2008). The report will include an update of the Australian Hydrogen Activity (2005).

Project leaders of the CSIRO alliance presented the results of their research to fellow members of the alliance and other stakeholders from government, academia and industry. The second day was more introspective and gave the members an opportunity to assess their research critically and review alliance progress half way through its 3-year term. The overall response to the workshop was very positive with attendees engaging in a lively discussion of developments in new materials for hydrogen production, storage and utilisation. The next alliance workshop will be held in Brisbane to coincide with WHEC2008 in June. International Standards Organisation to meet in Brisbane The International Standards Organisation, the peak body responsible for setting many technical standards throughout the world, has a technical committee (TC/197) that is devoted to hydrogen technologies. TC/197 will be holding a workshop and meeting two days before the start of the World Hydrogen Energy Conference in June this year. Anyone interested in taking part in the workshop should, in the first instance, contact Luigi Bonadio on (03) 9380 8274 or email [email protected].

After many months of organisation, the event is taking shape and promises to be a highlight on the AIE national calendar. Over 500 abstracts of oral and poster presentations have been received so far, on a wide range of topics: hydrogen production from coal, natural gas, biomass and renewables; high and low-temperature fuel cells; standards, safety and education; and outreach initiatives. A team of reviewers with specialised knowledge has been assembled to evaluate the submissions and upon completion, a draft conference program for will be published on the conference website www.whec2008.com which will be updated at regular intervals. Please check online for the latest updates. The overwhelming response by willing presenters has been matched by a high commitment to sponsorship. The premier sponsor for the event is the Queensland State Government, but substantial financial support is also provided by the Commonwealth Government (Department of Resources Energy and Tourism and Department of Education, Employment and Workplace Relations). Industrial sponsors include BOC, Linde and Rio Tinto and many other organisations are helping to market the event locally and internationally. The conference will stage an exhibition including national pavilions and booths from Canada, the United States, several European countries, and a variety of industry contributions from Australia. The conference comprises a series of plenary sessions each morning, with five parallel sessions of specialised topics in the afternoons. These will include sessions devoted to EnergyNews — Volume 26 No. 1 March 2008 27 Hydrogen Matters Continued commercialisation and finance in the hydrogen and fuel cell industry, and activities of the International Energy Agency and the International Partnership for the Hydrogen Economy. A special feature of WHEC2008 is the inaugural International Hydrogen and Fuel Cells (H&FC) Education Forum that will gather Australian and international students, teachers, academics and various government officials to participate in a series of coordinated lectures, workshops and presentations covering many aspects of H&FC technology. Student teams will work through a set of ‘hands-on’ practical activities while teachers engage in dedicated workshops to improve on the scope and quality of science-based school learning, particularly for engineering, design and technology subjects. The forum managers extend an invitation to all AIE members to attend the forum. Educators working at any level of the education system and industry representatives are welcome to participate and contribute to forum planning and delivery. The forum is proudly supported by Blue Cell Energy, Queensland Department of Education, Training and the Arts, Engineers Australia and the AIE, and is endorsed by the International Association for Hydrogen Energy.
