HighviewPower, plans to build a Europe’s largest liquid air storage facilities. Plant sizes are 50 MW, 250 MWh battery each, also the first one to be built in North of England, at the site of a decommissioned thermal power station.
What is Cryogenic Energy Storage?
As we know, the common low-temperature battery with LiFePO4, Lithium-polymer, and Lead-Acid we used around 0℃ to -60℃ cold environment, but in the heavy industrial field have various techniques to store electricity.
Cryogenic energy storage (CES) is the use of low temperature liquids such as liquid air or liquid nitrogen as energy storage. Both cryogens have been used to power cars. The inventor Peter Dearman initially developed a liquid air car, and then used the technology he developed for grid energy storage. (From Wikipedia)
According to the company’s explanation, The air turns to liquid when cooled down to -196°C (-320˚F), and can then be stored efficiently in insulated, low-pressure vessels. Exposure to ambient temperatures causes rapid re-gasification and a 700-fold expansion in volume, which is then used to drive a turbine and create electricity without combustion.
Cryogenic Battery in Commercial Used
To achieve the 50MW/250MWh “liquid air” facility program, Highview will first install the first commercial, large-scale cryogenic energy storage system in the UK, which says its low-temperature battery system technology has been successful in Pilsworth in Slough and GreaterManchester. The demonstration project was tested.
The installation of the cryogenic energy storage system is a decommissioned thermal power plant in the north of England, which serves to provide grid stability services to grid operators and the national grid. Highview believes its low-temperature energy storage facilities will help decarbonize industrial, power, transportation, and heating.
According to the news, the company’s low-temperature energy storage technology can store energy in a 10-hour, 200MW/2GWh system for several weeks at a cost of about £110/MWh ($143). Kawada said: “This low-temperature battery factory will provide key services to maintain a stable and reliable grid.” “Long-term, giga-class energy storage is the necessary foundation for realizing renewable energy, and achieving a 100% carbon-free future. key.”
This project will help the national grid integrate renewable energy and provide additional power supply security. The system is also expected to offer other services such as market arbitrage (while trading in different pricing markets), frequency management and grid constraint management.
As early as March of this year, Highview revealed plans to develop a GW-scale, long-term low-temperature energy storage system in cooperation with Spanish engineering procurement and construction specialist TSK. The joint venture HighviewTSK plans to develop projects in Spain, the Middle East, and South Africa by 2022.
With the emphasis on clean electricity, energy storage facilities for saving electricity have also been developed. According to BNEF’s forecast, the installed capacity of global energy storage facilities will reach 1095GW/2850GWh by 2040, and the construction of this scale will require 6620. Billions of dollars in investment. In addition to pumped storage, electrochemical energy storage, air energy storage and other energy storage technologies are increasingly entering our field of vision, and the future may enter our daily lives.
