A method for generating power and for gasifying a liquefied gas, the method including the steps of circulating a refrigerant as a working fluid in a closed circuit through a storage tank, a compressor, heating means including a first heat exchanger, a high pressure gas turbine, reheating means, a low pressure gas turbine, a second heat exchanger, a pump, and a heater, said second heat exchanger condensing the working fluid and gasifying said liquefied gas, said first heat exchanger absorbing exhaust heat from an industrial plant and heating both the working fluid and the gasified product of said liquefied gas, said gas turbines serving to extract mechanical power from the working fluid and being connected with electrical generators to produce electric power, the method also including the steps of conducting said liquefied gas and its produced gas in an open circuit through said second heat exchanger, said first heat exchanger and a pump withdrawing the produced gas, the method being characterized in that the working fluid has its critical temperature above the temperature of the exhaust gas of said industrial plant and has its freezing point below the entrance temperature of said liquefied gas in said second heat exchanger, and in that the working fluid in the circuit is maintained to experience temperatures well below the temperature of its substantial decomposition even in the presence of oil, water, iron and copper.
