Supercritical water gasification of biomass to produce hydrogen

Supercritical water gasification (SCWG) processes have recently received significant attention as a sustainable technology for the production of hydrogen starting from wet biomass. In this chapter, the influence of biomass composition for the production of hydrogen under SCWG is evaluated. The influence of the main reaction conditions as temperature, pressure and feed concentration on hydrogen yield are discussed together with a critical rationalization of data.
