Advanced Emission Solutions has invested £1.75m ($2.7m) in liquid air energy storage (LAES) developer Highview Power Storage (Highview).
Advanced Emission Solutions has signed a license agreement through its subsidiary ADA-ES with Highview for grid-connected LAES non-peaker plant storage applications covering North America (US, Canada and Mexico).
Highview’s LAES technology can be scaled to deliver large-scale, long duration energy storage from 5MW output and 15MWh of storage capacity to more than 50MW output and 200MWh of capacity. The technology liquefies air when refrigerated to -196°C and stores it in standard insulated, but unpressurised vessels at large scale. Exposure to ambient temperatures causes rapid re-gasification and a 700-fold expansion in volume, which is used to drive a turbine and create electricity.
US coal company ADA-ES aims to broad its portfolio with the investment in Highview. “We look forward to further developing the technology and application to meet our customer’s emerging energy challenges,” said ADA-ES CEO Michael Durham.
Highview has also added Michael Durham to its board of directors.
The UK-based company operates a grid-connected 350kW/2.5MWh pilot plant in Slough, UK, since 2010, and will deploy a new pre-commercial 5MW demonstrator near Manchester. The project is a collaboration with energy and waste management company Viridor and the UK Government’s Department of Energy and Climate Change (DECC).
