Advantages of Algae-based Carbon Capture

– Safe and sustainable – An onsite solution– Additional revenues

– Highest rates of CO2 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

CO2 Capture Potential

tonnes/acre/year

Seambiotic uses open ponds and captures 80 tonnes of CO2 per acre/year

RWE energy uses photobioreactor and captures 87 tonnes of CO2 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 EnergyThe Welsh Assembly Government

- More than $ 200 million investmentsRWE 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

Suitable algal strain selection

Land availability near power plant

Retrofitting algae systems in existing power plants

Economic viability

Industrial perception

Challenges yet to be addressed

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.
