Biomass gasification for sustainable energy production: A review

Gasification process is considered as one of the best routes of energy recovery from biomass by producing syngas mostly including H2, CO, and CH4. Biomass as the main renewable energy resources has great advantages regarding its diversity, availability, and sustainability for supplying energy needs in heat, electricity production, biofuel production for transportation, etc. Various gasifiers based on the gasifying process and agents have been examined. This paper reviewed the theory of biomass gasification by comparing and analyzing different gasification models-designs and configurations, also different operational conditions. It aimed to bring a holistic approach for hydrogen rich syngas production based on the present technologies, techno-economic analysis, and industrial/commercialization pathways. The biomass gasification technologies need to be improved for hydrogen production regarding the global environmental and economic issues. The review provided better insights into the enhancement of syngas production from biomass.
