Methods and Systems for the Co-Generation of Gaseous Fuels, Biochar, and Fertilizer From Biomass and Biogenic Wastes

摘要

Methods and systems for converting a biomass and biogenic wastes to hydrogen with integrated carbon dioxide capture and storage are disclosed. In some embodiments, the methods include the following: mixing at least one of a dry solid or liquid or liquid hydroxide and catalysts with a biomass to form a biomass mixture; heating the biomass mixture until the hydroxide and the biomass react to produce hydrogen, carbonate, biochar, and potentially fertilizer; calcining the carbonate or performing double replacement reactions of the carbonate to produce sequestration-ready carbon dioxide and a hydroxide; storing the carbon dioxide produced; transferring the hydrogen produced to a fuel cell; and generating electricity with the fuel cell.
