5 Issues with Algae Fuels Written by Robert Rapier
Here are 5 issues with Algae fuels that are covered in the book on jatropha and algae as fuel sources by Robert Rapier.
1. The present cost of algae production from open ponds is too high to make fuel production economically viable.
2. Photobioreactors (PBRs) are too expensive.
3. The energy inputs into the algae production process are very high.
4. Some algae don’t need sunlight, and can produce oil in a fermentor.
5. Don’t believe the cited per acre yields that some proponents claim.
