Abstract

Oxygenic photosynthetic microbes such as green algae and cyanobacteria are capable of simultaneously splitting water and generating O2 and H2. This property confers them the ability to directly utilize sunlight to produce a clean fuel, H2 gas. In this article, we discuss the two major classes of enzymes present in these organisms that are involved in H2 production, hydrogenases and nitrogenases. We also describe the major barriers that must be overcome to bring the process to commercial deployment, as well as recent technological advances in the area.
