Slough, UK – Atlas Copco compressors are being employed in a new cryogenic process developed by Highview Power Storage to store off-peak electric energy by liquefying air.

Using off-peak electricity, the Highview CryoEnergy System pilot plant operates by extracting ambient air from the surrounding environment: the gas is cleaned, compressed by Atlas Copco compressors, and then cooled until the air undergoes a phase change to a liquid. The liquefied air is stored in an insulated tank at a temperature of −196° C.
