COMBINED POWER GENERATION SYSTEM AND METHOD FOR CAPTURING CARBON DIOXIDE IN THE COMBINED POWER GENERATION SYSTEM

摘要

A combined cycle power generation system according to an embodiment of the present invention includes: a natural gas synthesis device that synthesizes methane through a methanation reactor after producing a synthesis gas in a gasifier by being supplied with coal and oxygen; a fuel cell device which generates electric energy by being supplied with a methane-containing fuel from the natural gas synthesis device; and a carbon dioxide supply unit that supplies a cathode electrode of the fuel cell device with carbon dioxide which is discharged from a carbon dioxide discharge facility adjacent to the fuel cell device.
