The invention discloses a methanol fuel ship SOFC/GT/ORC energy comprehensive utilization system coupled with carbon capture. The methanol fuel ship SOFC/GT/ORC energy comprehensive utilization system comprises an SOFC/GT system, a first-stage organic Rankine cycle power generation system and a second-stage organic Rankine cycle power generation system. According to the SOFC/GT system, methanol and water are mixed and enter a reforming chamber for a reforming reaction, reformed gas of the reforming reaction enters an SOFC anode, air is compressed by an air compressor and then enters an SOFC cathode and a post-combustion chamber, exhaust gas of the SOFC enters the post-combustion chamber to be combusted, and the exhaust gas is exhausted after acting through a gas turbine. Exhaust gas of the gas turbine is sequentially used for heating reformed gas and providing heat for the reforming chamber and then enters the CO2 membrane separation device for CO2 and waste gas separation; wherein CO2 is used for heating a mixture of methanol and water and serves as a heat source for driving circulation of the first-stage organic Rankine cycle power generation system and the second-stage organic Rankine cycle power generation system and then is cooled, liquefied and stored, and waste gas is used for heating the mixture of methanol and water and serves as a heat source for driving circulation of the first-stage organic Rankine cycle power generation system. Carbon dioxide emission during ship navigation is reduced, and the energy utilization efficiency of the system is improved.
