Compressed-air storage moves toward commercialization

Hydrostor Inc., a leader in compressed-air energy storage, is preparing to build two major facilities as the need for long-duration energy storage intensifies.

Dan Gearino reports for Inside Climate News.

In short:

Hydrostor’s first major project, Silver City Energy Storage Centre, will begin construction in Australia in late 2024, followed by Willow Rock Energy Storage Center in California.
These facilities will help address the need for long-duration storage, critical for filling gaps when wind and solar power are insufficient.
The Department of Energy recognizes the significance of long-duration storage for decarbonizing the energy grid, aiming to reduce costs by 90% within the decade.

Key quote:

“It’s a very simple system that just uses a hole in rock [plus] air and water.”

— Curtis VanWalleghem, CEO of Hydrostor Inc.

Why this matters:

Long-duration energy storage is the linchpin for a stable, renewable energy grid. Projects like Hydrostor's represent a significant step toward achieving ambitious climate goals by ensuring a reliable energy supply, particularly as reliance on wind and solar energy grows.
