Hydrostor Inc. Expands Global Footprint with Innovative Long-Duration Energy Storage Solutions and Major Projects in Australia, California, and Beyond

Oonagh O'Grady, VP of International Origination for Hydrostor Inc., introduces the company as a leader in long-duration energy storage. Founded 10-15 years ago in Toronto, Canada, Hydrostor now has offices across Australia and Europe with significant investment from entities like Goldman Sachs and Canadian Pension Plan Investments. The company's technology is based on advanced compressed air energy storage systems that utilize proprietary thermal management to store heat generated during compression processes. This system involves compressing air into underground caverns displacing water into surface reservoirs which helps maintain steady pressure levels without fossil fuels, offering higher efficiency rates due to hydrostatic compensator processes and flexible siting options using hard rock formations instead of salt caverns. Hydrostor's proven technology includes operational projects such as a two-megawatt installation in Ontario providing valuable performance data over five years. Upcoming ventures include major projects in New South Wales (Australia) and California (USA), both aiming at large-scale grid solutions with durations extending beyond traditional limits—up to 24 hours—in response to growing market demands for longer-duration storage capabilities globally. The company actively expands its portfolio within maturing markets like North America’s Quenty project while exploring opportunities under schemes like the UK's cap-and-floor initiative amidst broader European prospects showcased at events such as Munich's conference where further discussions are welcomed by their team present onsite.
