Take a look at how Hydrostor’s Willow Rock Energy Storage Center (WRESC) project in Kern County, California, is contributing to the state’s energy priorities:

What is A-CAES?

Advanced compressed air energy storage (A-CAES) is a technology that stores energy by compressing air and later releasing it to generate electricity. It is an enhanced form of traditional compressed air energy storage (CAES), which has been in use in California and other parts of the world for decades. Hydrostor’s key advancement is that A-CAES captures and stores the heat generated during the compression phase and uses it to reheat the air during expansion, which significantly improves efficiency while eliminating the use of fossil fuels for daily operations. This patented technology makes it a much more environmentally friendly and cost-effective method for large-scale, long-duration energy storage.

How can this solution benefit California’s grid?
