Title:
METHANE GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/233493
Kind Code:
A1
Abstract:
The methane generation system according to the present disclosure comprises: a methane generation unit having an electrolyzer that electrolyzes water to obtain hydrogen and a methane reactor that obtains a fuel gas containing methane by a methanation reaction using the hydrogen; a reformer that reforms the fuel gas to obtain a reformed gas; a fuel cell that generates power by a reaction that obtains a product gas from the reformed gas and an oxygen-containing gas; a recovery device that separates a recovery gas containing carbon dioxide from a return fluid that is part of the product gas; and a circulation channel that guides the recovery gas to the methane generation unit.
