According to the present invention, provided is an electric propulsion system including an electric propulsion unit for generating propulsion of a ship. The electric propulsion system comprises: a gas combustion unit generating combustion gas by burning gas fuel in a liquefied gas storage tank mounted on the ship; a turbine operating using the combustion gas as a driving fluid; a generator connected to the turbine to produce electricity to supply to the electric propulsion unit; a heat exchanger for cooling the driving fluid discharged from the turbine with a heat medium; and a compressor for pressurizing the driving fluid discharged from the heat exchanger and supplying it to the gas combustion unit.
