Algae could one day be major hydrogen fuel source
Date:4/1/2008

ARGONNE, Ill. (April 1, 2008) As gas prices continue to soar to record highs, motorists are crying out for an alternative that wont cramp their pocketbooks.

Scientists at U.S. Department of Energys Argonne National Laboratory are answering that call by working to chemically manipulate algae for production of the next generation of renewable fuels hydrogen gas.

We believe there is a fundamental advantage in looking at the production of hydrogen by photosynthesis as a renewable fuel, senior chemist David Tiede said. Right now, ethanol is being produced from corn, but generating ethanol from corn is a thermodynamically much more inefficient process.

Some varieties of algae, a kind of unicellular plant, contain an enzyme called hydrogenase that can create small amounts of hydrogen gas. Tiede said many believe this is used by Nature as a way to get rid of excess reducing equivalents that are produced under high light conditions, but there is little benefit to the plant.

Tiede and his group are trying to find a way to take the part of the enzyme that creates the gas and introduce it into the photosynthesis process.

The result would be a large amount of hydrogen gas, possibly on par with the amount of oxygen created.

Biology can do it, but its making it do it at 5-10 percent yield thats the problem, Tiede said. What we would like to do is take that catalyst out of hydrogenase and put into the photosynthetic protein framework. We are fortunate to have Professor Thomas Rauchfuss as a collaborator from the University of Illinois at Champaign-Urbana who is an expert on the synthesis of hydrogenase active site mimics.

Algae has several benefits over corn in fuel production. It can be grown in a closed system almost anywhere including deserts or even rooftops, and there is no competition for food or fertile soil. Algae is also easier to harvest because it has no roots or fruit and grows dispersed in water.'/>"/>
