Review demonstrates advanced catalysts and novel reactor designs for biomass gasification, highlighting pathways to overcome tar formation and low hydrogen yields.
Biomass gasification for hydrogen (H2) production provides outstanding advantages in terms of renewable energy resources, carbon neutral, high efficiency, and environmental benefits. However, the factors influencing H2 production from biomass gasification are complex, which makes determining the optimal operating conditions challenging. Biomass gasification also poses challenges owing to the high associated tar content and low gas yield, which need to be overcome. This review summarizes the influence of the gasification parameters on H2 production. Catalytic gasification technology and some of the latest catalysts, such as composites and special structure catalysts, are also summarized herein based on the requirements of high-purity H2 production. Moreover, novel technologies, such as staged gasification, chemical looping gasification, and adsorption-enhanced reforming for producing H2 rich gas are introduced. Finally, the challenges and prospects associated with biomass gasification for H2 production are presented.
