Hydrogen production from biomass gasification

One of the cleanest energy sources, hydrogen, is produced from renewable biomass, which is a promising feedstock for developing a sustainable bioenergy. The major methods for generating hydrogen from biomass are thermochemical processes such as gasification and pyrolysis. Despite the fact that biomass gasification, including steam and supercritical water gasification, exhibits a significant potential for field-scale applications, the selectivity and efficiency of hydrogen production must be improved to provide low-cost industrial applications with high atom economy. The two major biomass-to-hydrogen methods are examined in this article, along with the significance of operating conditions and factors that should be considered when designing a catalytic system. The difficulties and potential aspects of producing hydrogen through the gasification of biomass are examined to provide guidance on the crucial knowledge gaps that demand more research.
