Title:
DISTRIBUTED METHANATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/233500
Kind Code:
A1
Abstract:
The distributed methanation system (1) according to the present disclosure comprises a methane generation system (10) that includes a co-electrolyzer (11) and a methane reactor (12) and supplies power, water, and carbon dioxide to generate methane and a fuel cell power generation system (20) that includes a reformer (21) which converts methane supplied from the methane generation system (10) into hydrogen and a fuel cell (22) which generates power using hydrogen supplied from the reformer (21), wherein the fuel cell power generation system (20) comprises a circulation channel that recirculates hydrogen off-gas generated in the fuel cell (22) and a separator (24) that separates carbon dioxide from the hydrogen off-gas, and the distributed methanation system (1) also comprises a carbon dioxide recovery device (40) that recovers carbon dioxide separated by the separator (24).
