Hydrogen can be produced by a number of processes, including electrolysis of water, thermo catalytic reformation of hydrogen rich organic compounds, and biological processes. Biological production of hydrogen provides a wide range of approaches to generate hydrogen, including direct biophotolysis, indirect biophotolysis, photo-fermentation, and dark fermentation. Hitherto known biological hydrogen production processes have substantial potential for production of hydrogen on larger scales. However to develop a commercially viable technology from these processes requires an in-depth research into various aspects of production processes such as optimization of bioreactor designs, rapid removal and purification of gases, and genetic modification of enzyme pathways that compete with hydrogen producing enzyme systems offer exciting prospects for biohydrogen systems. This paper reviews various biological production processes for hydrogen, potential advantages of fermentative processes, possible utilization of organic fraction of MSW as raw material for hydrogen production.
