Cryogenic energy storage developer Highview Power has developed a scalable version of its technology to unlock new demand.
The CryoBattery, which is modular and scalable up to multiple gigawatts, can be located anywhere, according to Highview.
The technology can achieve a levelised cost of storage of $140 per megawatt hour (MWh) for a 10-hour, 200MW/2GWh system, says the company.
The system can enable renewable energy baseload power at large-scale, while also supporting electricity and distribution systems and providing energy security.
Highview Power’s proprietary cryogenic energy storage technology uses liquid air as the storage medium, provides all the services essential for a robust grid including time shifting, synchronous voltage support, frequency regulation and reserves, synchronous inertia, and black start capabilities.
Unlike competing long-duration technologies, such as pumped hydro-power or compressed air, Highview Power’s CryoBattery can be sited in various locations as it has a comparatively small footprint and does not require hazardous materials.
Highview Power chief executive Javier Cavada said: “As more and more renewables are added to the grid, long-duration, giga-scale energy storage is the necessary foundation to make these intermittent sources of power reliable enough to become baseload.
Not only does our CryoBattery deliver this reliability and allow scalability-it is proven, cost-effective, and available today.”
