The latest trend in power plants and the recent research is going on algae based CO2 capture to make powerplants more eco-friendly

Algae based CO2 capture

  1. 1. ALGAE BASED CO 2 CAPTURE
  2. 2. PREFACE <ul><li>Algae </li></ul><ul><li>Why algae? </li></ul><ul><li>Algae based CO 2 capture </li></ul><ul><li>Process of CO 2 capture </li></ul><ul><li>Comparison </li></ul><ul><li>Challenges to be faced </li></ul><ul><li>End products of algae </li></ul><ul><li>Benefits </li></ul>
  3. 3. ALGAES <ul><li>Algae are one of the important species on earth </li></ul><ul><li>They produce more oxygen than all other plants </li></ul><ul><li>They are food source for some animals </li></ul><ul><li>We will be able to produce biofuel from its processing </li></ul><ul><li>They can fix CO 2 in atmosphere </li></ul>
  4. 4. WHY ALGAE? <ul><li>Pollutants such as CO 2 and NO 2 can be controlled using algae </li></ul><ul><li>Algae use these as nutrients for its growth </li></ul><ul><li>They consume CO 2 a lot and that’s we need </li></ul><ul><li>About 1.8 tons of CO 2 required to produce 1 ton algae </li></ul><ul><li>A coal power plant produces 1 ton co 2 for every MW of energy produced </li></ul><ul><li>Monetary benefits from algae processing </li></ul>
  5. 5. ALGAE BASED CO 2 CAPTURE
  6. 6. PROCESS OF CO 2 CAPTURE
  7. 7. COMPARISON <ul><li>Algae based CO 2 capture </li></ul><ul><li>Biological way </li></ul><ul><li>Permanent sequestration </li></ul><ul><li>Productive reprocessing of algae </li></ul><ul><li>Requires more land area </li></ul><ul><li>Setting up an algae CO 2 capture plant costs much </li></ul><ul><li>Eco-friendly </li></ul><ul><li>Conventional capture methods </li></ul><ul><li>Machine way </li></ul><ul><li>Temporary capture </li></ul><ul><li>No productive reprocessing </li></ul><ul><li>Not much of a land area needed </li></ul><ul><li>Comparatively less cost </li></ul><ul><li>Non eco-friendly </li></ul>
  8. 8. CHALLENGES TO BE FACED <ul><li>The high cost of implementing the sequestration infrastructure </li></ul><ul><li>The limited availability of land space near power plants for building algae systems </li></ul><ul><li>There are some specific operational problems as well, which could result in significant inefficiencies. For instance, the algal concentration may become acidic on high CO 2 concentration </li></ul>
  9. 9. END PRODUCTS OF ALGAE
  10. 10. BENEFITS <ul><li>Sustainable </li></ul><ul><li>Ensures safety </li></ul><ul><li>Eliminates transportation of CO 2 </li></ul><ul><li>Biodiesel </li></ul><ul><li>Generates biomass </li></ul><ul><li>Additional revenues </li></ul>
