The UK just activated Highview Power's CRYOBattery near Manchester — the world's first commercial liquid air energy storage plant, storing surplus wind electricity by liquefying air to minus 196 degrees Celsius and releasing it as expanding gas to drive turbines during peak demand periods.

 

The UK just activated Highview Power's CRYOBattery near Manchester — the world's first commercial liquid air energy storage plant, storing surplus wind electricity by liquefying air to minus 196 degrees Celsius and releasing it as expanding gas to drive turbines during peak demand periods.

During surplus overnight wind generation, electric compressors cool atmospheric air into liquid stored in heavily insulated tanks. When grid demand peaks, liquid air warms and expands 700 times in volume, driving turbines generating electricity within minutes. Round-trip efficiency reaches 60 percent and energy stores for weeks without degradation — unlike batteries losing charge continuously.

Liquid air storage requires no lithium, cobalt, or specialist materials — only steel tanks and conventional industrial machinery already manufactured worldwide. The UK identified 50 sites suitable for CRYOBattery installations delivering 5,000 megawatts of long-duration storage collectively.
