Claim 0:
1. 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 MPa;
b. a liquid air recuperator fluidly connected to said cryogenic pump configured to heat said pressurized liquid air and produce vaporized air;
c. a combustor fluidly connected to said liquid air recuperator configured to burn a fuel in the presence of said vaporized air and produce combustor exhaust;
d. a first turbine fluidly connected to said combustor configured to extract power from said combustor exhaust and produce a first turbine exhaust wherein said first turbine exhaust is fluidly connected to said liquid air recuperator;
e. a separator fluidly connected to said liquid air recuperator wherein said separator is configured to separate liquid carbon dioxide from said first turbine exhaust; and
f. a second turbine fluidly connected to said separator to extract power from said first turbine exhaust.
