Abstract
Fossil fuel is the major source for almost all of our energy needs today, yet extensive consumption of fossil-based substances leads to problems of depleted reserve and side effects of severe environmental influences. Hydrogen is considered as "the fuel of future" mainly due to its high energy density and nonpolluting nature. Biohydrogen production is found to be less energy intensive and more environmental friendly as compared to thermochemical and electrochemical processes, while dark fermentation is the most applicable process for recovering hydrogen from wastes due to its higher rate of hydrogen evolution as well as the versatility of the substrates used. As the most abundant renewable carbon resource known with large enough capacity to substitute for fossil fuels, waste biomass is a promising substrate for biohydrogen production. This chapter presents basic concepts and fundamentals of biohydrogen production processes.
