Due to the considerable combustion heat value and common access, hydrogen constitutes a convenient energy carrier. The biological processes for obtaining hydrogen include the following: biophotolysis of water, fermentation and electrochemical processes (bio-electrolysis of water). During the bioproduction of hydrogen mainly renewable energy sources are used such as solar energy and organic substrates contained in industrial waste and waste materials. The development of these methods may become one of the ways of obtaining cheap and pure energy.
