Claim 13:
14. The system according to claim 13, wherein the cold box, when connected with the cryogenic energy compensation subsystem, further comprises at least one cryogenic energy compensation flow passage; the other branch of the two split branches of supercritical air split by the proportional adjustment device of the supercritical liquefaction subsystem enters the cryogenic energy compensation flow passage in the cold box of the staged cryogenic storage subsystem and cools, and then enters the cryogenic expansion unit to expand and cool further, and mixes with cryogenic air at the gas-side outlet of the gas-liquid separator in the mixer, the cryogenic energy is recovered by the cryogenic energy recovery flow passage in the cold box of the staged cryogenic storage subsystem, and then the air returns to the inlet of the multistage compressor or returns to gas paths between the stages of the multistage compressor.
