Liquid Air: Heralding a Breakthrough for Long-Duration Energy Storage?

Two major liquid air energy storage projects in the UK and China are moving toward operation, signaling commercial-scale long-duration storage deployment.

Highview Power’s Carrington plant and a 60 MW project in Golmud will store surplus renewable electricity as liquid air and release it later during peak demand.

The projects highlight liquid air storage as a potential tool to curb renewable curtailment, reduce negative power prices, and balance intermittent wind and solar.
