Hydrostor developing 1 GW of energy storage in California

Canada’s Hydrostor Inc announced today it is developing 1,000 MW/10,000 MWh of long-duration energy storage projects in California, where regulators have identified a need for up to 1,600 MW of such capacity by 2026.

The company said in a statement that it is actively working on two major projects that represent a combined investment of more than USD 1.5 billion (EUR 1.24bn). One is being developed in southern Kern County and the other is located in Central California.

Hydrostor noted that project development work such as transmission interconnection, engineering and permitting activities are well underway.

All projects will utilise the company’s Advanced Compressed Air Energy Storage (A-CAES) technology, which provides eight to 12 hours of energy storage. This compares to the one to four hours that current battery technologies can feasibly deliver, the company says.

“Long-duration storage is essential for decarbonizing the California electricity grid and integrating the renewable energy that is already developed in the state,” said CEO Curtis VanWalleghem.

Hydrostor’s overall pipeline includes near-term projects in the US, Canada, Chile and Australia, with a total potential surpassing 2,000 MW/20,000 MW.
