Highview Power Storage, a UK based designer and developer of innovative Liquid Air Energy Storage (LAES) systems, has signed a licence agreement with leading US clean coal technology provider, Advanced Emissions Solutions, Inc. of Denver, Colorado.

Advanced Emissions Solutions, Inc. through its subsidiary ADA-ES, has signed a licence agreement and invested £1.75m in Highview Power Storage. The licence agreement is for grid-connected LAES non-peaker plant storage applications covering North America (US, Canada and Mexico). ADA-ES, the leading clean coal technology specialists, are broadening their offering with their investment in Highview at a time when energy storage is proving to have a significant role to play in the electricity market, to help balance electricity systems and support intermittent renewables.

Highview, leaders in LAES systems, has operated a grid connected 350kW/2.5MWh pilot plant in Slough, Greater London since 2010, and is now working on deploying a new pre-commercial 5MW demonstrator, to be based in Greater Manchester, in collaboration with energy and waste management company Viridor and the UK Government’s Department of Energy and Climate Change (DECC).

LAES technology can be scaled to deliver large-scale, long duration energy storage from around 5MW output and 15MWh of storage capacity to significantly more than 50MW output and 200MWh of capacity. It can be considered as being similar to medium scale pumped hydro-electricity storage, but without the geographical restrictions of mountains and reservoirs.

Highview’s CEO, Gareth Brett said, “Signing the licence agreement with ADA-ES is a major step for Highview, and brings to an end an exciting and productive year for the company. We very much look forward to working with ADA-ES and drawing on their expertise in the US market to progress the technology even further. We also welcome their CEO, Dr. Michael Durham to our Board of Directors.”

Dr. Michael D. Durham, President and CEO of Advanced Emissions Solutions said, “We are very excited about working with Highview to bring this technology to markets in North America.  As we looked for the best technology for large grid-scale energy storage, we concluded that the LAES technology had significant advantages for this market and that Highview was years ahead of anyone else pursuing this approach. We look forward to further developing the technology and application to meet our customer’s emerging energy challenges.”
