Highview Power


Highview Power is a long-duration energy storage pioneer, specialising in cryogenic energy storage. It is based in the United Kingdom and the United States. It has permission for a commercial-scale 50 Megawatt/250 Megawatt-hour plant in England, building upon its earlier 5 Megawatt and 350 Kilowatt pilot plants. It plans to develop a 50MW plant/400MWh in Vermont.
It has over 30 patents developed in partnership with British universities and has won technology funding from the British Government.
In February 2020 Sumitomo Heavy Industries invested $46m in the company.

Technology

Its CRYOBattery™ technology uses low-cost electricity to cool air to -196 °C, reducing it to a liquid 1/700th the volume. At times of high demand for electricity, when prices are typically high, the liquid is expanded through a turbine to generate electricity, free of combustion and the resultant emissions. The process can utilise waste heat and waste cold to boost efficiency. The system utilises standard equipment from sectors like Liquified Natural Gas and, unlike short-duration energy storage technologies, doesn't require mining for, or complex recycling of, rare minerals.
