Cold heat reused air liquefaction/vaporization and storage gas turbine electric power system

An energy storage gas-turbine electric power generating system comprising:

• a liquid air storage for storing liquid air;
• a pump for raising the pressure of the liquid air from said liquid air storage;
• a cold energy regenerator for storing therein cold energy of the liquid air transferred through said pump while evaporating the liquid air to be high-pressure air;
• a combustor for burning fuel with the high pressure air from said cold energy regenerator to produce a combustion gas;
• a gas turbine driven by utilizing the combustion gas;
• a generator driven by said gas turbine for generating electric power;
• a liquefied fuel storage tank for storing liquefied fuel;
• a heat exchanger for heat-exchanging between heat medium and liquefied fuel from said liquefied fuel storage tank, the fuel after heat-exchanging in said heat exchanger being sent to said combustor to be burned with the high pressure air;
• and
• a compressor for compressing the air from said heat exchanger, the compressed air being sent to said cold energy regenerator and liquefied therein with cold energy stored therein, to be liquid air, and the liquid air being stored in said liquid air storage tank;
• wherein liquefaction of the compressed air and storage of cold energy of the liquid air while evaporating the liquid air are effected in said cold energy regenerator at different times.
