Claim 14:
15. A liquid air energy release apparatus comprising:
a. a liquid air storage apparatus containing liquid air and a cryogenic pump fluidly connected to said liquid air storage apparatus wherein said cryogenic pump is configured to provide pressurized liquid air at a pressure of greater than 0.52 M Pa;
b. an organic Rankine cooler connected to said cryogenic pump wherein said organic Rankine cooler contains a working fluid wherein said organic Rankine cooler is fluidly connected to a pump to increase the working fluid pressure, which said organic Rankine cooler is fluidly connected to an organic Rankine recuperator and organic Rankine heater, wherein said working fluid is expanded and is fluidly connected to a turbine to extract power from said expanded working fluid, and wherein said expanded working fluid is then passed through said organic Rankine recuperator and then back into said organic Rankine cooler and then into said pump;
c. a second liquid air recuperator fluidly connected to said organic Rankine cooler and a first liquid air recuperator connected to said second liquid air recuperator which second and first liquid air recuperators transfer heat to vaporized air;
d. a combustor fluidly connected to said second liquid air recuperator wherein said combustor burns fuel in the presence of said vaporized air and produces combustor exhaust;
e. a first turbine fluidly connected to said combustor to extract power from said combustor exhaust and produce a first turbine exhaust;
f. a water separator to remove liquid water from said first turbine exhaust;
g. a carbon dioxide separator to remove liquid carbon dioxide from said first turbine exhaust.
