Hydrostor to Develop 1 GW Energy Storage Facility in California

Hydrostor has announced the development of a 1 GW of long duration energy storage project in the state of California.

Hydrostor, a long-duration energy storage solution provider, announced the development of 1,000 MW (1 GW) of long duration energy storage project in the state of California.

The California Public Utilities Commission has identified a need for up to 1,600 MW of long duration energy storage by 2026. Long duration energy storage is critical to achieving California’s decarbonization and renewable goals. 

“Hydrostor is proud to play a critical role in the clean energy transition for the state, and looks forward to continuing to work with the Commission to establish its commercial pathway for long duration energy storage,” the firm stated.

The firm has two major projects now in active development – one in southern Kern County and one in Central California – representing a combined investment of over USD 1.5 billion USD, creating economic opportunities for Californians while supporting the transition to a carbon-free and renewable energy grid. Project development work including transmission interconnection, engineering and permitting activities are well underway. These are major capital projects that establish long-term clean energy infrastructure to the state using highly skilled union employment and provide significant economic benefits to the region.

Hydrostor’s patented and commercially proven A-CAES technology provides 8-12+ hours of energy storage, versus the 1-4 hours that current battery technologies can feasibly provide. This long duration energy storage is essential for establishing the pathway to California’s decarbonized electricity grid. A-CAES also has a longer lifespan, of more than 50 years, with zero degradation and a lower environmental impact than conventional alternatives available today.

Curtis VanWalleghem, CEO, Hydrostor, said, Long-duration storage is essential for decarbonizing the California electricity grid and integrating the renewable energy that is already developed in the state. Our A-CAES technology utilizes only existing, proven components that are repurposed from conventional power generation into an entirely emissions-free and low impact storage technology. Not only are we providing a clean, reliable and affordable long duration energy storage solution, but we’re also providing Californian workers and suppliers a more direct opportunity to be part of the clean energy transition.

The firm stated that it has been actively advancing its projects since 2017 to be ready for the state’s procurement initiatives which are now imminent, expanding its team and footprint in the state, and participating in California Public Utilities Commission (CPUC) proceedings advocating for long duration energy storage.

Hydrostor is advancing a pipeline of large-scale A-CAES facilities that represent over 2,000 MW and 20,000 MWh of near-term project deployment potential in the USA, Canada, Chile and Australia.
