The research breakthrough points to a highly scalable and renewable source of hydrogen that can be deployed as an additional system output in algae production settings.
To achieve this breakthrough, OriginOil researchers built a pared-down version of the company's Hydrogen Harvester and tested many process variables and materials.
They achieved hydrogen energy corresponding to a solar energy conversion efficiency of about 12 percent continuously for several hours on a partially clouded day. The sole energy input was the Sun. By comparison, commercial solar cells achieve conversion efficiencies between six and 20 percent.
