Objective To analyze algae-based CO 2  capture technology, its status, viability and future.
List of Contents Introduction Advantages of Algae-based Carbon Capture  Key Players in Algae-based Carbon Capture Technology Current Status of Key Players Success Points of Pilot Projects Challenges and Efforts Conclusion
Introduction Why CO 2  Capture?  Why Algae for CO 2  Capture? Algae -based CO 2  Capture Technology Flue gas Nutrients Sunlight
Advantages of Algae-based Carbon Capture Safe and sustainable  An onsite solution Additional revenues Highest rates of CO 2  uptake
Algae-based Carbon Capture vs Geological Sequestration Algae-based Technology Geological Sequestration Technology Sustainable Social problems arises Safe Untested on large scale No need to transport CO2 Need to transport CO2 to sequestration site Generates biomass No additional revenue Coupled with wastewater treatment Coupled with oil recovery $ = carbon credit + nutrient credit + biomass $ = carbon credit
Algae-based Carbon Capture Not a theory anymore !
The Key Players
Current Status of Key Players Companies Project phase RWE energy  Pilot Stage Portland General Electric Pilot Stage MBD Energy Pilot Stage  Seambiotic  Pilot Stage  Linc Energy  Research stage  Trident Exploration Research stage  NRG Energy Research stage  EniTecnologies Research stage  Glenturret Whisky distillery Research stage
Who Uses What? 3 pilot phase project uses  photobioreactor 1 uses open pond Open pond Closed pond Photobioreactor 4 Research Not yet tried 2 Research 1 Pilot 3  Pilot RWE energy  Portland General  Electric MBD Energy Seambiotic
CO 2  Capture Potential  tonnes/acre/year Seambiotic uses open ponds and captures  80 tonnes of CO 2  per acre/year  RWE energy uses photobioreactor and captures  87 tonnes of CO 2  per acre/ year
Biomass is a Bonus! Key Players End Use of Algae Seambiotic Food additives, Fish feed and biofuels MBD Algae oil Linc Energy Biodiesel, Fertilizers and power. Trident Exploration  Electricity RWE energy  Biogas plant Glenturret Whisky distillery  Animal feed for cattle and Shellfish farms
Success Points of Pilot Projects - 40-50% carbon dioxide capture - Companies capture both carbon dioxide and nitrous oxide - Algae are successfully cultivated in sub freezing temperatures by using the waste heat generated from coal plants. - Additional revenues.
Grants & Investments - More than $ 200 million grants  Department of Energy The Welsh Assembly Government  - More than $ 200 million investments RWE energy  MBD Energy
Bubbling of carbon dioxide E.g. By altering pH Energy intensive algae harvesting and drying E.g. Gravity settling  Low cost algae cultivation E.g. Wastewater cultivation Challenges addressed
Challenges yet to be addressed Suitable algal strain selection Land availability near power plant Retrofitting algae systems in existing power plants Economic viability Industrial perception
Conclusion Algae-based carbon capture technology  is in its initial stages of research. Preliminary  results suggest that there is a significant amount of investments  and industrial participation.  Hence, it is not a theory anymore  and could have a good GHG abatement potential in future.
