Abstract
A carbon dioxide capture system linked to water electrolysis equipment according to an embodiment of the present invention may comprise: water electrolysis equipment for producing hydrogen and oxygen from water or steam; a reformer for combusting a fuel using the oxygen; a boiler for generating steam using exhaust gas discharged from the reformer; a water-gas shift reactor for producing carbon dioxide and hydrogen from carbon monoxide contained in the exhaust gas discharged from the boiler; a regenerator for recovering exhaust heat from the exhaust gas discharged from the water-gas shift reactor; and an adsorber for adsorbing carbon dioxide from the exhaust gas.
