(3) Device for hydrogen generation using biomass fermentation: Biomass waste can be used as the raw material for CO2, and hydrogen generation using fermentation technology, and high-purity hydrogen can then be obtained using separation and purification devices. Possible source materials include agricultural waste, kitchen waste, and organic wastewater. Solid biomass waste requires effective pre-treatment before entering the fermentation process. The choice of fermentation approaches include: dark fermentation, light fermentation, and lightedark composite fermentation. Electric power is needed for the pre-treatment device, fermentation tank, gas separation and purification devices during the process of fermentation hydrogen generation from biomass, and this can be provided by the BHIRES itself.
