Algae can produce hydrogen fuel from water and sunlight, with a little boost from man-made nanoparticle catalysts, according to engineers at the U.S.Department of Energy's Argonne National Laboratory. By commandeering the photosynthesis mechanisms that enable algae to harness the energy of the sun, algae can produce abundant fuel to power an emerging hydrogen economy, they say.
Chemist Lisa Utschig tests a container of photosynthetic proteins linked with platinum nanoparticles, which can produce hydrogen from sunlight. Tiny bubbles of hydrogen are visible in the container at right.
Led by Argonne National Lab chemist Lisa Utschig, working with colleague David Tiede, the team at Argonne's Photosynthesis Group recently demonstrated how its platinum nanoparticles can be linked to key proteins in algae to coax them into producing hydrogen fuel five times more efficiently that the previous world record.
