Liquid-air energy storage: how does it compare to other storage types?
“The new liquid air battery, being developed by Highview Power, is due to be operational in 2022 and will be able to power up to 200,000 homes for five hours, and store power for many weeks.”
“The Highview battery will store 250MWh of energy, almost double the amount stored by the biggest chemical battery, built by Tesla in South Australia.”
“The project will cost £85m, and Highview received £35m of investment from the Japanese machinery giant Sumitomo in February.”

“At approximately £110/MWh for a 10-hour, 200MW/2GWh system, the CRYOBattery offers a competitive levelised cost of storage for large-scale applications. By comparison, a new pumped-hydro plant would have an levelised cost of storage of $152-198 per MWh, with a comparable lithium-ion system costing $285-581/MWh, according to analyst Lazard.”
