The present invention provides a heat exchange system based on gas hydrate replacement which can capture methane gas while securing the structural stability of seabed sediment and bury carbon dioxide. According to one embodiment of the present invention, the heat exchange system based on gas hydrate replacement comprises: a capturing part injecting carbon dioxide into a CH_4 hydrate sediment layer buried in seabed sediment to induce a methane-carbon dioxide replacement reaction, and capturing mixed gas including carbon dioxide and methane gas; a separation part dissolving carbon dioxide in the captured mixed gas in an absorbent to induce a creation reaction of CO_2 hydrate slurry, and separating and storing methane gas; and a dissociation part dissociating carbon dioxide from the created CO_2 hydrate slurry to exchange heat with an external object. 본 발명의 일 실시예에 따른 가스 하이드레이트 치환 기반의 열교환 시스템은 해저 퇴적물에 부존하는 CH4 하이드레이트 퇴적층에 이산화탄소를 주입하여 메탄-이산화탄소 치환 반응을 유도하고, 메탄 가스와 이산화탄소를 포함하는 혼합 가스를 포집하는 포집부; 포집된 혼합 가스 중 이산화탄소를 흡수제에 용해시켜 CO2 하이드레이트 슬러리의 생성 반응을 유도하고, 메탄 가스를 분리 저장하는 분리부; 및 생성된 CO2 하이드레이트 슬러리로부터 이산화탄소를 해리시켜 외부 대상물과 열교환시키는 해리부;를 포함하는 가스 하이드레이트 치환 기반의 열교환 시스템.
