U.K. Backs Liquid Air in Search for Way to Store Renewable Power

February 13, 2014

The U.K. backed plans to turn air into liquid as a way to store energy from volatile solar and wind plants, granting more than 8 million pounds ($13 million).

The Department of Energy and Climate Change awarded funds to a partnership of Viridor Waste Management Ltd. and Highview Power Storage to seek to commercialize the technology and link it to the grid, it said today in an e-mailed statement.

Excess power, when demand is too low to soak up all that’s generated, will be used to turn air into liquid under the plans. The liquid can then be turned back into gas to drive a piston or turbine. Energy storage is becoming increasingly important as economies shift to using unpredictable sources of power from the sun and wind. The U.K. seeks to get 15 percent of its energy from renewable sources by 2020, up from about 9.4 percent now.
