But what IS the cost of power ????? The cost of energy as perceived by the public has no scientific justification Oil cartel (!!!!) Taxes Political manipulation Ignorance Emotion Environmental and social impact JAKARTA (AFP) – Les négociations sur le réchauffement climatique cette semaine à Bangkok s'inscrivent dans un contexte de critiques sévères contre les biocarburants, qui ne sont plus désormais considérés comme une solution miracle. La combustion d'un carburant issu de la canne à sucre, du maïs ou du palmier à huile est plus propre que celle d'un carburant fossile. Mais les experts assurent que la demande en biocarburants entraîne des effets fâcheux pour l'économie et la sécurité alimentaire mondiales, et pourrait finalement l'environnement. 02/04/2008 causer davantage de mal que de bien à "It is widely understood that as populations and economies grow global demand for energy will increase, but the hard truth is that energy demand is accelerating. Under a business-as-usual scenario worldwide energy demand is estimated to grow by 60% over today's levels. Demand for energy in China and India alone is expected to grow at over 3.4% per annum to exceed 5300 million tonnes of oil equivalent by 2030." "If provided by an energy system similar to today's, that is to say largely using energy from fossil fuels, carbon dioxide emissions can be expected to exceed 14.7 billion tonnes by 2030, an increase of fifty five percent above current levels. This would spell imminent disaster for mankind." "We believe that coal use will increase under any foreseeable scenario because it is cheap and abundant. Coal can provide usable energy at a cost of between $1 and $2 per MMBtu compared to $6 to $12 per MMBtu for oil and natural gas. Moreover, coal resources are distributed in regions of the world other than the Persian Gulf, the unstable region that contains the largest reserves of oil and gas." "In particular the United States, China and India have immense coal reserves. For them, as well as for importers of coal in Europe and East Asia, economics and security of supply are significant incentives for the continuing use of coal. Carbon-free technologies, chiefly nuclear and renewable energy for electricity, will also play an important role in a carbon-constrained world, but absent a technological breakthrough that we do not foresee, coal, in significant quantities, will remain indispensable." GM awards battery development contracts for Volt : Detroit, June 5 2007 (Reuters) - General Motors Corp. said on Tuesday that it had awarded two advanced battery development contracts for work on its electric-driven Chevrolet Volt car. A division of Germany's Continental AG and Compact Power Inc., a unit of South Korea-based LG Chem Ltd. won the contracts to develop the next-generation lithium-ion batteries for the Volt. GM has said it was aiming to build the mass-market Volt by 2010 if it makes a battery pack to drive the vehicle cheaply enough and ensure its safe operation. ..... The push to develop environmentally friendly cars is an attempt by GM to distance itself from its close association with gas-guzzling sport utility vehicles, a reputation executives say has hampered its sales in some markets. This misleading nonsense is worth 4 080 000 pages of free web publicity for BMW. Once the media have convinced the general public that hydrogen is the key to our energy future, no politician will dare to claim the opposite. Search Google for: "Hydrogen sustainable transport" : 2 470 000 web pages "Hydrogen inefficient transport" : 511 000 web pages. How many press articles ask the question where this marvellous fuel came from, and how much energy was consumed (elsewhere) to produce it ? "In a culture like ours, long accustomed to splitting and dividing all things as a means of control, it is sometimes a bit of a shock to be reminded that, in operational and practical fact, the medium is the message." Marshall McLuhan, University of Toronto, 1964 Four months later, on May 31, 1807, Emperor Napoleon granted a 15 year patent to Isaac François de Rivaz, citizen of the Republic of Valais, for his discovery of the hydrogen-fuelled Internal Combustion engine. The decree was published in the October 1807 issue of the "Bulletin des Lois de l'Empire Français". For a brief historical introduction, please refer to the hydrogen page of www.aecono.com. Many thanks to the personnel of the Archives de l'Etat du Valais, in Sion, who kindly provided numerical copies of the 1807 patent granted to Isaac de Rivaz, a remarkable personality who more than 200 years ago invented the hydrogen-fuelled internal combustion engine.

With the exhaustion of fossil resources the energy economy will change from a chemical to an electrical base. This transition is one of physics, not one of politics. It must be based on proven technology and existing engineering experience. The transition process will take many years and should start soon. Unfortunately, politics seems to listen to the advice of visionaries and lobby groups. Bossel: Does a Hydrogen Economy Make Sense?

Such IGCC (Integrated Gasification Combined Cycle) technology can also be fuelled by asphalt, refinery waste or petroleum coke. The syngas can also be converted by Fisher-Tropsch technology to produce synthetic high-quality diesel fuel, naphtha, LPG and methanol. The methanol can be used as base chemical, it can power fuel cell vehicles, or it can be upgraded to high-octane gasoline. Coal-based power generation and fuel synthesis, however, generate large amounts of CO2, and are sustainable only if the carbon dioxide is efficiently captured and sequestered. Industrial sites that integrate coal gasification, power generation and the production of syngas-derived chemicals with reliable sequestration of CO2 will provide opportunities for buffering electric power requirements through large-scale storage of hydrogen. Such storage facilities may also serve to fuel buses and other transportation vehicles for which the low energy to volume ratio of hydrogen is not as serious a problem as for private cars. http://www.hyweb.de/Knowledge/w-i-energiew-eng4.html The British chemical concern ICI stores hydrogen in three brine compensated salt caverns in Teeside, England. The hydrogen is stored at pressures up to 50 bar in these up to 366 m deep caverns. From 1957 until 1974, GAZ DE FRANCE stored towngas with a 50% hydrogen content without problem in a 330 Mio. m3 aquifer storage. This underground hydrogen storage method is about two orders of magnitude cheaper than tank storage. http://www.h2cars.biz/artman/publish/article_152.shtml Madrid, Spain; partners are Air Liquide, Gaz Natural, Repsol YPF and EMT Madrid; hydrogen is produced onsite from natural gas by a Carbotech compact reformer, H2 back-up supply is provided by CGH2 tube trailers from chemical byproduct generation, This is the first CUTE station to become operative by APR2003 (http://www.h2cars.de/filling/h2fueling.html) High-energy career lines Virginia Gewin, Nature 434, 936-937 (14 April 2005) In addition, safety precautions required by the characteristics of hydrogen (low ignition energy, broad flammability range, risk of destructive shock-wave detonation when confined) will be more reliably mastered in an industrial site than at a highway gas station. Preparing a possible future for hydrogen as an energy carrier, I would argue, does not require highway filling stations, but technology for large-scale sequestration of CO2, development of industrial fuel cells and efficient electrolysers for power buffering, and large-scale, safe storage of hydrogen that preferably avoids energyintensive liquefaction.
