The invention discloses a liquefied air energy storage system, an energy storage ship and an offshore renewable energy transportation method.The liquefied air energy storage system comprises an air liquefaction system and a power generation system, and the power generation system comprises a liquefied air circulation power generation system, a first working medium circulation power generation system and a second working medium circulation power generation system; the first working medium circulation power generation system and the second working medium circulation power generation system provide part of heat for liquid air power generation in the power generation process. The energy storage ship comprises the liquefied air energy storage system, and the liquefied air energy storage system provides electric energy for an air liquefaction system and serves as an offshore renewable energy power system. According to the marine renewable energy transportation method, through an energy storage ship, air is used as an energy carrier, marine renewable energy is stored on the ship in the form of liquefied air, and then the ship is transferred to the vicinity of a coast to generate power through the liquefied air. According to the invention, the problems of global offshore wind power energy storage and transportation can be solved with high efficiency and low cost, the construction and maintenance cost of an offshore power transmission system can be greatly reduced, and the system is suitable for all global sea areas.
