Researchers at the University of California at Berkeley have engineered a strain of green microalgae that could, with further refinements, produce vast amounts of hydrogen through photosynthesis. The breakthrough also could have application in a wide range of products, from biodiesel to cosmetics. Present efficiency is at around 30 cents / kW-h. In 2000, when the technology was first announced, they were at 300 cents / kW-h.

Theoretical optimum is at 3 cents / kW-h. This is based on observation of normal photosynthesis processes. It is also based on a marketing model of on-site hydrogen production and conversion to electricity, not requiring hydrogen storage and transport.

Methods of improving efficiency for commercial application include:

Hydrogen fuel production by a process of microalgal photosynthesis - University topic site.

: "Hydrogen fuel and electricity may become the primary 21st century energy carriers in California and the nation. Modification of photosynthesis in green algae may permit the generation of hydrogen gas as a clean, renewable and economically viable fuel. However, specific biological problems associated with sustained photosynthetic production of hydrogen gas require solutions."

Directory:Solar Hydrogen / Directory:Algae > OriginOil Achieves Hydrogen Production Comparable To Photovoltaics - OriginOil intends the Hydrogen Harvester to be deployed as an additional system output in algae production settings, approaching an efficiency of 12 percent when exposed to the sun. An advantage is that algae stores up energy during the day and will continue to generate hydrogen throughout the night. (Biofuel Daily November 11, 2010)
