Biohydrogen
From Wikipedia, the free encyclopedia
Biohydrogen is hydrogen produced via biological processes or from biomass.
Biohydrogen plants are proposed industrial plants for the production of hydrogen. They would typically involve processes such as thermophillic fermentation, photofermentation and gas cleaning [1]. Biohydrogen production can also involve an element of anaerobic digestion where the methane from biogas is converted through steam reforming into hydrogen [2].
Hydrogen is can be produced by bacterial species such as Rhodobacter sphaeroides and Enterobacter cloacae [3].
