Hitachi invests in UK company developing liquid air energy
storage solutions

Hitachi Industrial Equipment Systems Co., Ltd. (hereinafter, HIES) is investing in Innovatium Group Limited (hereinafter, Innovatium), a UK company developing the PRISMA liquid air energy storage (LAES) solution.

As global demand for electricity continues to rise, particularly in data centers, there is an increasing need for efficient and cost-effective methods to store energy. This is driven by the growing reliance on renewable energy sources, which have fluctuating supply levels. Innovatium’s PRISMA solution stores compressed air generated from renewable energy by cooling and liquefying it, and then converts it back into compressed air to drive generators when needed. It offers advantages such as low environmental impact, minimal waste emissions, and a longer lifespan compared to current mainstream lithium-ion batteries.

HIES will sell air compressors for PRISMA and expand sales of the PRISMA system through its Hitachi Global Air Power and HIES Europe sales channels. We will expand sales channels for air compressors in markets with high growth potential, such as data centers, with the aim of further growing our business.
