Highview Power has developed a modular cryogenic energy storage system—the CRYOBattery—that is scalable up to multiple gigawatts of energy storage and can be located anywhere. This technology reaches a new benchmark for a levelized cost of storage (LCOS) of $140/MWh for a 10-hour, 200 MW/2 GWh system.
Highview Power says that its cryogenic energy storage system is equivalent in performance to, and could potentially replace, a fossil fuel power station.
Highview Power’s systems 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. Air turns to liquid when cooled down to -196 °C (-320 ˚F), and can then be stored very efficiently in insulated, low-pressure vessels. Exposure to ambient temperatures causes rapid re-gasification and a 700-fold expansion in volume, which is then used to drive a turbine and create electricity without combustion.
Unlike competing long-duration technologies, such as pumped hydro-power or compressed air, Highview Power’s CRYOBattery can be sited just about anywhere. The CRYOBattery has a small footprint, even at multiple gigawatt-levels, and does not use hazardous materials.
Other locatable, long-duration energy storage technologies—such as Lithium-ion—typically offer a range of 4-8 hours of storage, whereas Highview Power’s CRYOBattery offers multiple gigawatt hours of storage, representing weeks’ worth of storage, not just hours or days.
Over the last 15 years, Highview Power—through the design, construction, and operation of its CRYOBattery technology—has developed and optimized its own proprietary BLU core controller system. The system embodies the sum of Highview Power’s market-leading knowledge and expertise into a complete facility management system. The BLU controller seamlessly integrates the control of all CRYOBattery components to provide optimal facility performance—managing the balance between flexibility, efficiency, and response.
The BLU controller enables a system to be configured to a particular application through the selection of individual operational modes. It also provides operation and performance monitoring feedback, ensuring a facility’s optimal efficiency. The system’s embedded flexibility further ensures that the controller has the built-in capacity to adapt as a facility’s demand varies with market development.
Highview Power has partnered with Finland-based Citec to modularize its gigawatt-scale cryogenic energy storage system. With a simplified design and streamlined engineering from Citec, a standard CRYOBattery configuration of 50 MW/500 MWh can be easily, and cost-effectively, scaled up to multiple gigawatt hours.
Highview Power recently won the 2019 Ashden Award for Energy Innovation with its proprietary CRYOBattery technology.
