Collaboration will see Baker Hughes put compressors, expanders, motors and generators into compressed air energy storage projects.
At its annual meeting in Florence, energy solutions company Baker Hughes announced a deal with long duration energy storage firm Hydrostor.
Baker Hughes will supply 1.4GW of power technology – including compressors, expanders, motors and generators – to Hydrostor’s advanced compressed air energy storage solutions.
Hydrostor is already operating the 2MW Goderich Energy Storage Centre in Canada – where the company is headquartered – and has two others under development: the 200MW Silver City Energy Storage Centre in Australia, and the 500MW Willow Rock Energy Storage Centre in California.
Baker Hughes has been an investor in Hydrostor since 2019 and this week’s deal marks an expansion of the collaboration.

Baker Hughes chief executive Lorenzo Simonelli said that “increasing pressure on electric grids is making long-duration energy storage an urgent priority. Hydrostor's innovative approach offers a low-carbon solution to ensure power reliability across a diverse mix of generation resources."
His Hydrostor counterpart, Curtis VanWalleghem, said the deal is timely “as load grows and AI data centre infrastructure is being built out globally”.
Resilience and reliability
Hydrostor’s Vice President of International Origination, Oonagh O’Grady, was a speaker at Enlit Europe in Bilbao, and ahead of the event she wrote exclusively for Enlit World, highlighting the potential of long duration energy storage for Europe.
She said long duration energy storage “delivers the flexibility, resilience and reliability needed to balance intermittent renewables. It’s not a support act – it’s strategic infrastructure. Without it, Europe risks decades of gas lock-in, stranded assets and exposure to volatile global markets.”
To unlock the potential of long duration energy storage, she said Europe must “move from ambition to action and embed LDES into policy frameworks. That means setting megawatt targets, creating transparent procurement schedules and unlocking private capital. The technologies are ready. What’s needed now is strategic foresight and coordinated execution.”
