Hydrostor 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 that is synchronous and emission-free, and can be flexibly located, including as replacements for retired fossil fuel plants. The proprietary technology is now the leading low-cost bulk energy storage solution -- at half the cost of lithium ion batteries and 10 times the lifespan. Hydrostor is backed by sustainable infrastructure developer/funder Meridiam and equipment supplier BakerHughesGE.
