Vegetable biomass – source of green hydrogen production through gasification

Through the gasification of vegetable (agricultural) biomass, as well as forest biomass, a combustible gas with a significant content of green hydrogen is obtained. This fuel will have to be integrated into a neutral society from the point of view of hydrogen emission, over the concept issued in Kyoto in 1996. In the paper, in the first part, solutions for an ecological transition society are analyzed. The progress achieved in CO2 gas capture allows, for the transition period, the parallel use of renewable energy sources with those that use fossil or synthetic fuels. The achievements in the field of biomass gasification are discussed in the second part of the paper. The gasification of vegetable biomass is in an early phase, of research and achievements at the stage of pilot plants. The work contains results of the gasification of vegetable biomass, on a 4 kW pilot plant, with references to the quality of the fuel gas obtained, both by the hydrogen content and by the calorific power. The paper also contains an image regarding the combustion of gasogen gas, during the gasification of vegetable biomass represented by walnut shells. The results obtained allow a further development for the valorization of plant biomass, with a significant integration into the neutral society from the point of view of CO2 emission.
