FIRST Minister John Swinney has hailed the announcement that an energy firm will look to build the “largest liquid air energy facility in the world” in Ayrshire.
The SNP leader welcomed executives with Highview Power to Scotland House in London on Monday as they laid out plans to develop a 2.5GWh liquid air energy storage (LAES) plant at Hunterston.
An LAES system uses air to store energy. When there is an excess, it cools air into a liquid and stores it. Then, when there is demand, that liquid can be warmed up, spinning turbines and creating electricity as needed.
Highview said that its Hunterston site will deliver five times Scotland’s current operational battery storage capacity and “is strategically placed in the grid transmission network to maximise the use of Scottish-produced renewable electricity”.
“Scotland presents a unique environment for innovation and deployment of storage technologies and this ground-breaking project will bring hundreds of high skilled jobs to the region both during construction and afterwards in supporting the supply chain.”
Highview said that the Hunterston project will support 1000 jobs onsite during construction and 650 jobs in the supply chain.
Richard Butland, the firm’s chief executive, said: “We were delighted to meet the First Minister today, and thrilled to announce our next project in Hunterston, the first of four, which kick starts our multi-billion-pound LDES [long duration energy storage] programme across the UK to unlock 10GWh of LDES.”

“This project will be transformational for Scotland in providing critical storage for offshore wind and solving grid constraints as well as delivering major investment in Ayrshire, and the wider region.”
Highview Power said its programme of four will also include a project in Aberdeenshire, “strategically positioned to support the onshoring of renewable energy resources from the North Sea and the critical need for grid stability at this location”.
The firm is expected to publish more details of that second Scottish project in the coming months.
Chris O’Shea, group chief executive at Centrica, said: “It is fantastic to see our partners at Highview Power expanding with their new project at Hunterston.
“LDES will be vital to unlocking the UK’s energy potential, and Highview’s technology will be a key part of that. With innovation and investment, the UK will achieve its ambitious net zero goals.”
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
