World’s first liquid air energy storage plant uses Atlas Copco, Plant Engineer

Using cheap, off-peak electricity, the CryoEnergy System pilot plant operates by extracting ambient air from the surrounding environment.

Rob Morgan chief technology officer at Highview, explains that the gas is cleaned, compressed and then cooled until it liquefies. Liquefied air is then stored in an insulated tank at -196° C.

Compressors for world’s first liquid air energy storage plant, The Engineer

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.

Atlas Copco compressors form integral part of world’s first liquid air energy storage plant, Process and Control Today

The liquefaction stage is accomplished by integrating Atlas Copco compressors within Highview’s 300kW/2.5MWh CryoEnergy System. A fully-integrated, oil-free ZR 700 VSD water-cooled screw compressor, with specially modified inlet pipework, operates within the recirculation system while the main air feed for the liquefaction plant is supplied by a ZR 250 VSD rotary screw compressor. The Atlas Copco installation is completed with a low-pressure ZS45+ VSD blower.

Cold Storage, Energy World

Being able to store energy in large quantities is seen as the key to accommodating ever more intermittent power generation onto the grid, and storage is also very useful working alongside CHP plants. Here, David Strahan describes a new technology option currently under development.

Deals signals greater Sino-British co-operation on green economy, clean Biz Asia

Chinese Premier Wen Jiabao’s calls for Britain and China to work together on the green economy and jointly pursue sustainable development bore fruit yesterday when trade deals worth USD4.3 billion were signed by Wen and British Prime Minister David Cameron.

In another sign of increased economic co-operation between the two nations in the cleantech space, is a UK and Chinese collaboration announced yesterday will deliver the world’s first pilot “cryogenic energy storage” plant in the south-east of the UK.

The system, designed with scientists from the University of Leeds, uses liquefied air to store off-peak energy which the developers say can be used on a utility scale and is significantly cheaper than batteries. The energy storage technology has been developed by UK company Highview Power Storage and the demonstration site in Slough is due to be operational next month.
