Title:
METHANE GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/233494
Kind Code:
A1
Abstract:
A methane generation system according to the present disclosure includes: a water supply path for supplying water or steam; a carbon dioxide supply path for supplying carbon dioxide; a power supply path for supplying power; an SOEC co-electrolysis device to which the water supply path, the carbon dioxide supply path, and the power supply path are connected; a methane reactor; a connection path connecting the SOEC co-electrolysis apparatus and the methane reactor; and a first heat exchange unit for performing heat exchange between the SOEC co-electrolysis device and the methane reactor.
