US DOE Offers US$1.76 billion Loan To Hydrostor For A-CAES California Project
The title of this post, is the same as that of this article on Energy Storage News.
These three paragraphs give more detail.
The US Department of Energy’s (DOE) Loan Programs Office (LPO) has made a conditional commitment for a loan to long-duration energy storage (LDES) developer and operator Hydrostor of up to US$1.76 billion.
If finalised, the loan would be used to help fund the Willow Rock Energy Storage Centre, a 500MW/4,000MWh, 8-hour advanced compressed air energy storage system (A-CAES) in Eastern Kern County, California, led by Hydrostor subsidiary GEM A-CAES.
Compressed air energy storage (CAES) charges by pressurising air and funnelling it into a storage medium, often a salt cavern, and discharges it by releasing the compressed air through a heating system, which expands air before it is sent through a turbine generator.
Note.
- Both the Canadian Hydrostor and the British Highview Power use air in their batteries, with the Canadians using compressed air, often in salt caverns and the British using liquid air in tanks.
- Highview Power’s first large scale battery will be 200MW/2.5GWh, which is about half the size of Hydrostor’s, which will be 500MW/4.0GWh.
- Having mathematically-modeled large tanks full of chemicals in the 1970s for ICI, I wouldn’t be surprised, if the Highview Power battery is more easily scalable.
This could be an interesting technological shootout.
Complicating matters could be Trump’s policies to big batteries.

Analysts Say Gives A Reasoned.
Higher battery material tariffs and phased-down IRA tax credits threaten a 15% drop in U.S. storage deployment through 2035 in a “worst-case” scenario,
BNEF analysts said.
