Title:
METHANE PRODUCTION SYSTEM AND METHANE PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/191069
Kind Code:
A1
Abstract:
A methane production system (1) that comprises a co-electrolysis/reformation cell (32) and a control unit (60) that controls the operating temperature of the co-electrolysis/reformation cell (32). The co-electrolysis/reformation cell (32) operates in a co-electrolysis mode in which H2 and CO are generated at a first electrode (2) from CO2 and H2O or a reformation mode in which CH4 is generated at the first electrode (2) from the H2 and CO generated in the co-electrolysis mode. The control unit (60) makes the operating temperature of the co-electrolysis/reformation cell (32) in the reformation mode lower than the operating temperature of the co-electrolysis/reformation cell (32) in the co-electrolysis mode.
