Claim 3:
4. The system according to claim 3, wherein the staged cryogenic storage subsystem further comprises at least one evaporation cold box, and the evaporation cold box and the liquefaction cold box share at least one deep cooling cryogenic storage cycle and at least one intermediate cooling cryogenic storage cycle,
wherein the evaporation cold box comprises at least one deep cooling cycle internal flow passage, at least one intermediate cooling cycle internal flow passage, and at least one supercritical flow passage,
wherein the deep cooling cryogenic storage cycle is connected with the evaporation cold box to store cryogenic energy from the deep cooling temperature to the room temperature,
wherein the intermediate cooling cryogenic storage cycle is connected with the evaporation cold box to store cryogenic energy from the deep cooling temperature to the intermediate cooling temperature or to release cryogenic energy from the intermediate cooling temperature to the room temperature.
