Claim 16:
17. The method according to claim 15, wherein the storing and/or releasing cryogenic energy by the staged cryogenic storage subsystem when the gaseous air or the liquid air is converted comprises:
driving cycle working medium by a cycle fan to input cryogenic energy in a deep cooling storage tank and an intermediate cooling storage tank into a deep cooling cycle internal flow passage and an intermediate cooling cycle internal flow passage in the liquefaction cold box respectively, to provide supercritical air in a supercritical flow passage with cryogenic energy for liquefaction; and
driving cycle working medium by the cycle fan to input cryogenic energy in a deep cooling storage tank and an intermediate cooling storage tank into a deep cooling cycle internal flow passage and an intermediate cooling cycle internal flow passage in the evaporation cold box respectively, to provide supercritical air in a supercritical flow passage with heat energy for evaporation and store cryogenic energy.
