A process for transmitting or storing energy in which a gasseous working fluid is compressed and cooled, relative to isentropic compression, by a coolant. The energy used to perform the compression is recovered by expansion, while heat from the coolant is used to reheat the working fluid, thus maximizing efficiency.

[ I claim:] [1.] A process for storing and transmitting energy comprising the steps ofa) compressing a gaseous working fluid with a compressor apparatus employing input mechanical energy, thereby creating heat energy in the working fluid and the compressor apparatus,b) cooling the working fluid and the compressor apparatus by mixing with the working fluid a coolant fluid which absorbs heat energy from the working fluid and the compressor apparatus while mixing with and being compressed with the working fluid,c) storing the compressed mixture of working fluid and cooling fluid in a pressure vessel, andd) withdrawing the compressed mixture from the pressure vessel through an expander which extracts mechanical energy from the compressed mixture.
