Backround
⅔ Water
Sea algae
Biofuels development
Offshore industry
What? Who?
Algae refinement (suom. jalostus) for each area
“Green image” for offshore industry ? KnowHow?
3rd party organization? WHO?
Large “fields” to open sea capturing CO2
Time frame and estimated impact
Algae: continuous process - Processed into biofuel?
Low cost of growing, water nutrition byself
Sea good to capture CO2 - Plenty of it to “eat”
Current state
● Multiple small-scale experiments
● Some algae have been shown to absorb
up to 100x CO2 compared to trees
● Closed loop systems
● If used for biofuel the consumed CO2 is
released when consumed
● Inefficient and requires a lot of water
● High cost
Process
● Feed waste CO2 and heat into algae
tank
● Using sun as a power source for
photosynthesis bind carbon and
release O2
● Harvest algae for biofuel or other
carbon based products
● Rinse and repeat
Challenges
Weather
Motivation of offshore industry
Scale vs. other activities at sea
Effects to other species
The effectiveness of the algae?
Absorbs only CO2
Expensive at the moment
Conclusion
Offshore industry has the money, but will we get them motivation to start?
Huge potential in new areas to use for “production”
Potentially environmental-friendly biofuel and less carbon oxide?
