Energy efficient compressors

Energy-efficient Atlas Copco compressors are reported to be a vital part of an innovative cryogenic process developed by Highview Power Storage to store offpeak electric energy by liquefying air.

Using cheap 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.

The liquefaction stage is accomplished by integrating Atlas Copco compressors within Highview's 300kW/ 2.5MWh
