Energy Live News: Highview Power announces plans to develop liquid air energy storage system in US

Highview Power Storage and Encore Renewable Energy have announced plans to build what they claim will be the first long-duration, liquid air energy storage system in the US.

The facility, which will have a capacity of at least 50MW, is to be located in northern Vermont.

The technology uses excess or off-peak electricity to clean and compress air at subzero temperatures – when electricity is in high demand and more valuable, the pressurised gas is allowed to warm, turning a turbine as it expands and generating energy in the process.
