Hydrostor provides an Advanced Compressed Air Energy Storage (A-CAES), a technology uniquely suited to enable the transition to a cleaner, more reliable electricity grid. A-CAES provides grid services that are not readily replicated by other storage technologies, giving it unique market potential. It flexibly addresses bulk 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 located where required by the grid, including the ability to replace retired fossil fuel plants and the need for a new transmission. ​ Hydrostor offers a complete solution including financing and warranty, working with leading EPC providers to help deliver solutions globally.
