Biomass gasification is a process that converts solid biomass into a combustible gas called producer gas. It's a thermochemical conversion process that involves the partial oxidation of biomass at high temperatures. The process uses heat, steam, and oxygen to convert biomass to hydrogen and other products without combustion.  Biomass gasification is a simple, reliable, and low-cost process that can produce biofuel, hydrogen, syngas, and electricity. It's a mature technology pathway that concentrates on decentralized compact systems and processes for generating electrical and thermal energy... Show more
