Hydrostor is developing a large-scale advanced compressed air energy storage (A-CAES) project in Greater Napanee, Ontario – “right in Hydrostor’s backyard” – as the Canadian company’s CEO and co-founder, Curtis VanWalleghem, said following the project announcement.

The planned Quinte Energy Storage Centre will deploy Hydrostor’s A-CAES technology for long-duration energy storage (LDES) for a lifetime of 50 years. The company expects the project to be operational in “the early 2030s.”
