ABSTRACT
Hydrogen is considered as a novel fuel for the 21st century, mainly due to its environmentally benign character. Production of hydrogen from renewable biomass has several advantages compared to that of fossil fuels. A number of processes are being practiced for efcient and economic conversion and utilization of biomass to hydrogen. Biohydrogen production from organic wastes is attractive due to two reasons: as a gaseous fuel production; and bioremediation. A limited number of pilot plant studies are reported and also little information on the economic analyses of biohydrogen production processes is available.
