Long-duration energy storage using LAES CryoBattery

Overview

Highview Power develops and operates long-duration energy storage using CRYOBattery, a liquid air energy storage (LAES) system that cools air to -196°C, stores it as liquid in insulated tanks, and later warms it to drive a turbine and generate electricity without combustion. The process recovers waste heat from liquefaction and waste cold from re-gasification to improve efficiency, enabling grid-scale storage from around four hours to multiple weeks. They build, own, and operate LAES facilities for utilities and grid operators, offering services that stabilize grids, firm up renewable power, and provide backup capacity. Their approach centers on large-scale, long-duration storage with a closed-loop cryogenic cycle, highlighted by milestones like the world’s first LAES pilot in 2011 and the 300 MWh Carrington project, aiming to expand renewable deployment and support decarbonization.

Simplify's Take

What believers are saying

  • Centrica, UK Infrastructure Bank, and Rio Tinto backed £300 million in 2024.
  • Carrington under construction in Trafford targets 2026 operation and 480,000-home equivalent storage.
  • Ofgem advanced Highview’s Scottish and Lincolnshire projects toward summer 2026 support awards.

What critics are saying

  • Ofgem’s 2026 cap-and-floor decision can reject Hunterston and Killingholme, crippling expansion.
  • Lithium-ion BESS dominated Ofgem’s shortlist; Highview’s novel LAES fights proven incumbents.
  • Carrington remains unproven commercially until 2026; any commissioning slip damages credibility.

What makes Highview unique

  • Highview’s LAES avoids combustion and uses existing grid infrastructure at Carrington, 2026.
  • Carrington’s phase one stabilizes the grid, while phase two stores 300MWh.
  • Hunterston and Killingholme give Highview a rare pipeline of 3.2GWh projects.

Ice-Cold Long Duration Energy Storage System Ready For Takeoff

Sign up for daily news updates from CleanTechnica on email. Or follow us on Google NewsLong duration energy storage systems are the key to unlocking more global wind and solar power, but there’s a catch. The “long” in long duration is a difficult feat of engineering, and investors have been reluctant to take a chance on new breakthrough technologies. Nevertheless, the finance dam has been cracking, as just demonstrated by the long duration storage innovator Highview Power.The Long Duration Energy Storage Investment Dam Is CrackingCleanTechnica first took note of Highview Power’s “liquid air” battery all the way back in 2011, which just goes to show how difficult it is to stir the financial pot when new energy storage technology is involved. The initial proof-of-concept system weighed in at just 300 kilowatts at the time.We’ve been following Highview’s long duration journey since then, including a bump up to a 50-megawatt system planned for Vermont.That project was put to bed in 2022, after Highview identified some additional opportunities elsewhere around the globe, including the company’s home turf of the UK.And that’s where the investor dollars begin to flow.Highview contacted CleanTechnica by email earlier this week to draw our attention to its latest press release, which announces that the global mining powerhouse Rio Tinto, the UK Infrastructure Bank, and global engineering firm Centrica have chipped in together for a £300 million investment, aimed at enabling Highview to construct the first utility-scale liquid air storage facility in the UK.That comes on top of a £35 million stake from Sumitomo Heavy Industries announced in 2020. That same year, Highview also announced a partnership with the energy firm Carlton Power to build five liquid air “CRYObattery” facilities, totaling 1 gigawatt.“First up is a 50 MW / 250 MWh liquid air battery in Greater Manchester, which won a £10 million grant from the UK Department for Business, Energy & Industrial Strategy,” CleanTechnica reported.“So, here’s where it gets interesting,” we added

“Liquid Air” Energy Storage Could Save The Day For Offshore Wind Industry

Sign up for daily news updates from CleanTechnica on email. Or follow us on Google NewsOffshore wind fans have been getting a reality check of late, bedeviled by high costs and market uncertainties. Nevertheless, long duration energy storage could come to the rescue. The leading wind developer Ørsted, for one, is banking on a new high tech “liquid air” energy storage system, and they have reportedly seen good results from an initial analysis.Liquid Air For Long Duration Energy StorageLithium-ion battery arrays have been doing much of the heavy lifting for renewable energy storage, but their job is mainly limited to daily cycles lasting a few hours. A cap of about 4-6 hours is the rule of thumb, though systems lasting up to 8 hours are beginning to emerge.Long duration energy storage systems of 10 hours or more — including days, weeks, months, or whole seasons — are needed in order to shunt more wind and solar energy into the grid.Large scale, long duration systems are already in use today, but mainly in the form of pumped hydropower systems. Their application geographically limited
