Providing grid-scale electricity storage by storing renewable energy as compressed air

Hydrostor, a private company founded in 2010 and based in Toronto, Canada, is a leader in Advanced Compressed Air Energy Storage (A-CAES), a technology uniquely suited to enable the transition to a cleaner, more reliable electricity grid. A-CAES helps address electricity system needs for dispatchable capacity, renewable integration and optimization, transmission deferral and ancillary services, and is ideal for use in behind-the-meter or remote applications for mines and large industrial operations. Hydrostor’s solution delivers low-cost, long duration bulk energy storage (hundreds of MWs, 4-24+ hours) that is synchronous and emission-free, and can be flexibly located, including the ability to repurpose retired coal plants and leverage existing mining infrastructure. The proprietary technology is now the leading low-cost bulk energy storage solution – at 1/3 the cost of lithium ion batteries and 5x the lifespan. Hydrostor has multiple projects in operation or under construction in Australia and Canada, as well as numerous projects in advanced development globally.
