Long-duration energy storage firm Highview has developed the world’s first giga-scale cryogenic battery.

The cryogenic, can be located anywhere, is scalable to up to a 10-hour 200MW/2GWh system. Long energy duration energy storage currently on the market, such as lithium-ion batteries, range between 4 to 8 hours.

The new system provides up to weeks of energy storage

The cryogenic system is equivalent in performance to a fossil fuel power plant.

The system can enable renewable energy to be used as baseload at large scale, whilst supporting energy security.

The cryogenic system uses liquid air as the storage medium to provide grid operators with time shifting, synchronous voltage support, frequency regulation and reserves, synchronous inertia, and black start capabilities.

The developer claims the system has a small carbon footprint compared to other energy storage types.

Alex Eller, senior research analyst with Navigant Research, said, “Long-duration technologies such as cryogenic energy storage will become increasingly necessary for an electricity system to transition from a primary reliance on conventional fossil fuel generation to a grid dominated by variable renewable generation from solar and wind.”

“This is a pivotal moment for the renewable energy industry and for anyone who wants to deploy large amounts of renewables,” said Javier Cavada, president and CEO of Highview Power. “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.”

The solution provider has won the 2019 Ashden Award for Energy Innovation with its proprietary CRYOBattery technology.
