Advance in technologies of hydrogen production from biomass
生物质制氢技术研究进展

As a flexible energy carrier that can be produced from a variety of resources and with comprehensive uses, hydrogen is one of the most promising substitutes for fossil. It is certain that renewable-based hydrogen will be quite important in the future especially hydrogen from biomass which has series of unique merits. Technologies of hydrogen production from biomss mainly contains two kinds of processes, one is thermochemical route, including biomass/waste gasification, biomass pyrolysis, hydrogen from biomass-derived methane/ methanol/ethanol; The other is biological route, including direct biophotolysis, indirect biophotolysis, photo fermentation, hydrogen synthesis via the water-gas-shift reaction of photoheterotrophic bacteria, dark fermentation and microbial fuel cells etc. The developments of various hydrogen production processes from biomass are imtroduced and updated, and the trends of these processes are indicated.
