To produce hydrogen from biomass, gasification from biomass followed by reforming of the product gas is usually employed. Since reforming of the product gas, mainly composed of hydrogen, methane, carbon dioxide, and carbon monoxide into hydrogen-rich gas is a well-developed technology, efforts on technology development now targets biomass gasification. There are several technologies available for biomass gasification, each favoring specific type of biomass. This paper reviews the status quo and prospects of these biomass gasification technologies in terms of hydrogen production from biomass.
