Microalgae as a hydrogen source Posted by Natalia on Sun January 30 2011 12:15:22 AM 4

Microalgae absorb sunlight and through photosynthesis can produce hydrogen gas. In theory these microalgae can produce hydrogen, in practice it is much more complicated.

The first barrier to hydrogen production is that the microalgae produce oxygen as part of the photosynthesis process, which inhibits the gene expression required to produce hydrogen.

In on a Webinar hosted by the DOE’s Fuel Cell Technologies Program on “Improving Photosynthesis for Hydrogen and Fuels Production”. Dr. Tasios Melis gave a great presentation about his work in developing microalgae that produce hydrogen, as a renewable fuel source.

The basics of Dr. Melis’ research is that microalgae absorb sunlight and through photosynthesis can produce hydrogen gas.

 The webinar is part of a series put on by the Fuel Cell Technologies Program.

DOE funds $ 3m for Renewable Algal Energy LLC Posted by Natalia on Fri September 17 2010 11:01:32 PM 5

Algal biofuels ($3 million)
Renewable Algal Energy, LLC (Kingsport, Tenn.)  Algal Biodiesel via Innovative Harvesting and Aquaculture Systems  Renewable Algal Energy LLC, will leverage its experience in algal aquaculture, harvesting, and extraction, to demonstrate at small commercial-scale, improved, low cost, energy-efficient methods for harvesting and dewatering algae that contribute to an algal oil product that is cost-competitive with petroleum. 


The integration of their technology with up- and down-stream processes will reduce technical and economic risks for future scale-up to a full-scale commercial process. DOE Funding: $3,000,000
