AECOM is teaming up with Canadian start-up Hydrostor to get a foothold in the booming energy storage market. Under the deal, AECOM is licensing Hydrostor’s Terra technology and serving as EPC for projects the companies develop.
The technology uses the principles of compressed-air storage. But by drilling deep underground caverns and filling them with water, it creates an isobaric environment that improves the efficiency of the process.
