en.Wedoany.com Reported - Energy technology developer Airengy has signed a cooperation agreement with real estate company Hagag Europe to develop a compressed air power plant (CAPP) project in Romania, utilizing Airengy's AirBattery technology for energy storage. The project will use abandoned salt caverns from mining as storage reservoirs, aiming to provide multi-day, long-duration, grid-scale, dispatchable clean electricity.

This will be the largest facility applying AirBattery technology; Airengy currently operates only a 250 kW demonstration site in Israel. The first phase of the project will have a power capacity of over 1 MW and an energy storage capacity of approximately 200 MWh. Airengy stated that reaching the megawatt scale is significant for the technology to qualify for schemes such as the UK's LDES cap and floor mechanism. The second phase of the agreement plans to expand the discharge power to grid scale, providing approximately 25 MW of power and an energy storage capacity of about 5 GWh.

Currently, the world's largest compressed air energy storage power station, with a capacity of 2.4 GWh, was commissioned in China at the end of January this year. Airengy claims that its long-duration energy storage solution is unattainable with common technologies. This agreement in Romania follows the company's signing of memorandums of understanding with North Sea infrastructure and gas storage company Kistos in the UK and German energy company SEFE. Airengy is headquartered in Israel, while Hagag Europe is a real estate company based in Bucharest, Romania, and is part of the Hagag Group, also from Israel.

Airengy Chairman Yiftah Ron-Tal stated that the agreement with Hagag Europe marks the company's transition from development and proof-of-concept to commercialization, beginning the construction of commercial-scale power plants based on this technology. Hagag Europe Chairman Tzachi Hagag noted that using natural geological formations such as salt caverns offers significant economic and operational advantages over existing energy storage solutions.
