Cryogenic compressed air solar energy storage cabinet system

When it is cheaper (usually at night), electricity is used to cool air from the atmosphere to -195 °C using the to the point where it liquefies. The liquid air, which takes up one-thousandth of the volume of the gas, can be kept for a long time in a large at . At times of, the liquid air is pumped at high pressure into a, which acts as a boiler. Ai. [PDF Version]
