Hydrostor Inc. was named as finalist of the The smarter E AWARD 2025 in the Category "Energy Storage" for the application of its A-Compressed Air Energy Storage (A-CAES).
With its Advanced Compressed Air Energy Storage System, Hydrostor has developed an emission-free variant of a compressed-air energy storage system with an 8 to 24 hour storage duration. The heat generated during compression is stored and added back to the process during decompression. Additional heating with fossil fuels is no longer necessary. At locations near the power grid, conventional mining technologies are used to create storage volume. These are filled with water and supplemented by an above-ground reservoir. Pressurized air pushes the water into the upper reservoir; when discharging, the process is reversed. Hydrostor indicates an area requirement that is about 10 times smaller compared to conventional pumped-storage power plants and a project pipeline of currently 7.5 GW.
