"UK Energy Plant To Use Liquid Air"

"Work is beginning on what is thought to be the world's first major plant to store energy in the form of liquid air.

It will use surplus electricity from wind farms at night to compress air so hard that it becomes a liquid at -196 Celsius.

Then when there is a peak in demand in a day or a month, the liquid air will be warmed so it expands.

The resulting rush of air will drive a turbine to make electricity, which can be sold back to the grid."
