Abstract
An integrated gas turbine cycle and liquid air energy conversion system is provided that utilizes very high pressure air stream(s) produced from vaporization of a supercritical liquid air against a low pressure cryogenic gas. The cooled, low pressure cryogenic gas is then cold compressed to yield a moderate pressure cryogenic gas stream(s). Both the very high pressure air stream(s) and the moderate pressure air stream(s) are warmed in the flue gas heat exchanger associated with the gas turbine cycle. A source of electrical power is produced from the expansion of combustion gas in a gas turbine while auxiliary sources of electrical power are produced from the turbine expansion of the warmed very high pressure air streams and moderate pressure cryogenic gas streams. The combustion gas includes a moderate pressure supplemental stream originating from the supercritical liquid air or from the cold compressed cryogenic gas.
