UK to introduce liquid air energy storage to the US

Highview Power Storage, a UK-based designer and developer of Liquid Air Energy Storage (LAES) systems, has signed a licence agreement with Advanced Emissions Solutions of Denver, Colorado.

The agreement is for grid-connected LAES non-peaker plant storage applications covering the US, Canada and Mexico.

Advanced Emissions Solutions chief executive Michael Durham 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”.

Advanced Emissions Solutions has invested £1.75m in Highview.

Highview has operated a grid-connected 350kW/2.5MWh pilot plant in Slough since 2010.

It 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 Department of Energy & Climate Change (DECC).

According to Highview, 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.

According to the Liquid Air Energy Network (LAEN), the use of liquid air for grid-based energy storage could increase energy security, cut greenhouse gas emissions and create a new industry for the UK worth at least £1bn per annum, along with 22,000 jobs.
