Status Of CO2 Capture Using Algae

  1. 2. Objective <ul><ul><li>To analyze algae-based CO 2 capture technology, its status, viability and future. </li></ul></ul>
  2. 3. List of Contents <ul><li>Introduction </li></ul><ul><li>Advantages of Algae-based Carbon Capture </li></ul><ul><li>Key Players in Algae-based Carbon Capture Technology </li></ul><ul><li>Current Status of Key Players </li></ul><ul><li>Success Points of Pilot Projects </li></ul><ul><li>Challenges and Efforts </li></ul><ul><li>Conclusion </li></ul>
  3. 4. Introduction <ul><li>Why CO 2 Capture? </li></ul><ul><li>Why Algae for CO 2 Capture? </li></ul><ul><li>Algae -based CO 2 Capture Technology </li></ul>Flue gas Nutrients Sunlight
  4. 5. Advantages of Algae-based Carbon Capture <ul><ul><li>Safe and sustainable </li></ul></ul><ul><ul><li>An onsite solution </li></ul></ul><ul><ul><li>Additional revenues </li></ul></ul><ul><ul><li>Highest rates of CO 2 uptake </li></ul></ul>
  5. 6. 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
  6. 7. Algae-based Carbon Capture <ul><li>Not a theory anymore ! </li></ul>
  7. 8. The Key Players
  8. 9. 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
  9. 10. 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 <ul><ul><li>RWE energy </li></ul></ul><ul><ul><li>Portland General Electric </li></ul></ul><ul><ul><li>MBD Energy </li></ul></ul><ul><li>Seambiotic </li></ul>
  10. 11. 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
  11. 12. 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
  12. 13. Success Points of Pilot Projects <ul><li>- 40-50% carbon dioxide capture </li></ul><ul><li>- Companies capture both carbon dioxide and nitrous oxide </li></ul><ul><li>- Algae are successfully cultivated in sub freezing temperatures by using the waste heat generated from coal plants. </li></ul><ul><li>- Additional revenues. </li></ul>
  13. 14. Grants & Investments <ul><li>- More than $ 200 million grants </li></ul><ul><ul><ul><ul><li>Department of Energy </li></ul></ul></ul></ul><ul><ul><ul><ul><li>The Welsh Assembly Government </li></ul></ul></ul></ul><ul><li>- More than $ 200 million investments </li></ul><ul><ul><ul><ul><li>RWE energy </li></ul></ul></ul></ul><ul><ul><ul><ul><li>MBD Energy </li></ul></ul></ul></ul>
  14. 15. <ul><ul><li>Bubbling of carbon dioxide </li></ul></ul><ul><ul><ul><li>E.g. By altering pH </li></ul></ul></ul><ul><ul><li>Energy intensive algae harvesting and drying </li></ul></ul><ul><ul><ul><li>E.g. Gravity settling </li></ul></ul></ul><ul><ul><li>Low cost algae cultivation </li></ul></ul><ul><ul><ul><li>E.g. Wastewater cultivation </li></ul></ul></ul>Challenges addressed
  15. 16. Challenges yet to be addressed <ul><ul><li>Suitable algal strain selection </li></ul></ul><ul><ul><li>Land availability near power plant </li></ul></ul><ul><ul><li>Retrofitting algae systems in existing power plants </li></ul></ul><ul><ul><li>Economic viability </li></ul></ul><ul><ul><li>Industrial perception </li></ul></ul>
  16. 17. Conclusion <ul><li>Algae-based carbon capture technology is in its initial stages of research. </li></ul><ul><li>Preliminary results suggest that there is a significant amount of investments and industrial participation. </li></ul><ul><li>Hence, it is not a theory anymore and could have a good GHG abatement potential in future. </li></ul>
