Highview Power Storage and Encore Renewable Energy have announced plans to develop the United States’ first long duration, liquid air energy storage system. This facility will be a minimum of 50MW, provide in excess of eight hours of storage (400MWh) and will be located in northern Vermont, USA. The facility will enable the efficient transport of excess power from renewable energy sources, such as solar and wind power to help integrate them on the power grid.
With Highview Power’s liquid air energy storage solution, called CryoBattery, excess or off-peak electricity is used to clean and compress air which is then stored in liquid form in insulated tanks at temperatures approaching 320 degrees below zero Fahrenheit (-196 C). When electricity is in high demand and more valuable, the pressurized gas is allowed to warm, turning a turbine as it expands and thus generating energy that can be used at peak times when the sun is not shining and the wind is not blowing.
Highview Power and Encore are in discussions with potential utility and transmission grid operator customers regarding the capabilities and services the facility can provide.
