Hydrostor is a leading developer and operator of long-duration energy storage systems. Hydrostor leverages a proven technology solution for delivering long-duration energy storage (eight hours or more) to power grids around the world. Hydrostor’s technology uses compressed air and water to store energy. This patented technology allows grid operators to draw on clean energy, even when there is no sun to fuel solar panels and no wind to generate energy from turbines.

Hydrostor has a successful utility scale facility commercially contracted to the Independent Electricity System Operator (IESO) located in Goderich, Ontario, and two advanced projects under development in Kern County, California and New South Wales, Australia. Hydrostor has an extensive early-stage pipeline of projects in North America, Australia and Europe.

Founded in 2010 and with headquarters in Toronto, Canada and offices in Melbourne, Australia and Sacramento, USA, Hydrostor is backed by Goldman Sachs Asset Management, the Canada Pension Plan (CPP) and other forward-thinking institutional investors, providing financial security to commit to top-tier energy projects.
