Biohydrogen

Microbial hydrogen production.

Biohydrogen is H2 that is produced biologically.[1] Interest is high in this technology because H2 is a clean fuel and can be readily produced from certain kinds of biomass,[2] including biological waste.[3] Furthermore some photosynthetic microorganisms are capable to produce H2 directly from water splitting using light as energy source.[4][5]

Besides the promising possibilities of biological hydrogen production, many challenges characterize this technology. First challenges include those intrinsic to H2, such as storage and transportation of an explosive noncondensible gas. Additionally, hydrogen producing organisms are poisoned by O2 and yields of H2 are often low.
