Hydrostor

Hydrostor is a developer of utility-scale energy storage facilities that can be flexibly sited using its proprietary Advanced Compressed Air Energy Storage (A-CAES) technology and purpose-built underground storage caverns. A-CAES is unique as a grid storage solution: it provides low-cost bulk long-duration storage like pumped hydro, but has the key ability to be flexibly sited where the grid needs it, allowing the targeting of high-value (and immediately available) grid applications like transmission deferral and fossil plant replacement. The technology operates similarly to a conventional natural gas plant but is entirely non-emitting, is much more cost-effective than batteries at scale with a 50+-year asset life, and is ideally suited to providing the long-duration storage resource necessary for decarbonizing the grid. Hydrostor has three projects in operation or under construction in Canada and Australia, and is advancing a pipeline of large-scale A-CAES projects that already represents over 2 GW and 16 GWh of deployment potential in the USA, Canada, Chile and Australia.
