Hydrogen production from biomass holds the greatest promise, since biomass is abundantly available everywhere in the world. However, hydrogen from biomass has major challenges. The yield of hydrogen is low from biomass since the hydrogen content in biomass is low to begin with (approximately 6%) and the energy content is low due to the 40% oxygen content of biomass. A novel gasification method for hydrogen production from carbonaceous materials using a CO2 sorbent has been widely used. It mainly uses steam as gasification agent. For this study the above method has been adopted to test if it will work for air-blown biomass gasifiers. The main purpose of this project is to enhance the yield of hydrogen from air-blown biomass gasification process. The produced hydrogen will be further separated and purified for fuel cell application. Ultimate and proximate analyses of the biomass material were conducted and the obtained results were used for the simulations in order to determine the efficiency of the gasifier with biomass and biomass/sorbent blends. It was found that the biomass/sorbent blends increase the yield of not only H2 but also other syngas constituents such as CO leading to enhancement of the gasifier efficiency since it is dependent on the volume of combustible gases.
