True Long Duration Energy Storage


Unlocking the full potential of renewable energy – making it as reliable and affordable as conventional power options – depends on the availability of large-scale, long-duration energy storage. To support an energy market transformation toward 100% renewable energy, Sumitomo SHI FW provides liquid air energy storage technology that delivers clean, reliable, and cost-efficient energy storage. This technology will enable users to bring gigawatt hours of energy storage to the market, with the flexibility to be built practically anywhere it is needed.

Liquid air energy storage technology makes use of a freely available resource—air—which is cooled and stored as a liquid and then converted back into a pressurized gas to drive turbines and produce electricity. Sumitomo SHI FW has entered into a strategic partnership with Highview Power to commercialize these liquid air energy storage systems. This technology provides the only long-duration energy storage solution available today that offers multiple gigawatt hours of storage, scalability, siting flexibility and zero emissions. Highview Power’s 5 MW/15 MWh Pilsworth plant in the United Kingdom is the world’s first grid-connected liquid air energy storage system. The facility provides essential balancing services to the U.K. grid and demonstrates the commercial readiness of this technology for flexible and clean long-duration energy storage.

Liquid air energy storage is adaptable and can provide services at all levels of the electricity system: supporting power generation, providing stabilization services to transmission grids and distribution networks, and acting as a source of backup power to end users.
