Hydrostor lands $230M to scale compressed-air storage pipeline
What's the deal? Canadian long-duration energy storage developer Hydrostor has raised $230 million (€199.5 million) in growth equity to advance its global pipeline of advanced compressed air energy storage projects.
What's the endgame? Hydrostor builds systems that store energy as compressed air for later release, aimed at delivering power over long durations. The funding will support its pipeline, including the 500MW Willow Rock project in the US.
Why it matters: The raise signals investor appetite for storage that can shift power across hours or days as grids add intermittent wind and solar.
The signal: Long-duration storage is drawing capital as grids need ways to balance variable renewable generation and extend storage beyond the shorter windows offered by lithium-ion batteries.
