Baker Hughes, Hydrostor deepen strategic collaboration

Energy technology company Baker Hughes and Hydrostor, a global long duration energy storage (LDES) developer and operator, announced a strategic technology solutions and equity agreement during the 2026 Baker Hughes Annual Meeting in Florence, Italy.

Under the agreement, Baker Hughes’ technology capabilities will be integrated as part of Hydrostor’s core design offering for its advanced compressed air energy storage (A-CAES) solution. This includes up to 1.4 GW of Baker Hughes equipment orders for Hydrostor’s flagship projects.

“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,” said Lorenzo Simonelli, chairman and CEO of Baker Hughes. “We are proud to support Hydrostor with critical technology to accelerate these projects, supporting greater global grid resilience and enabling sustainable power systems at scale.”

Baker Hughes has been an investor in Hydrostor since 2019. This latest strategic agreement marks an expansion of the relationship as Hydrostor nears construction on its flagship projects in the U.S. and Australia.

In the initial phase of the expansion, Hydrostor will be deploying up to 1.4 GW of power generation and compression technology solutions from Baker Hughes’ portfolio including compression, expander, motor and generator technology.

“The agreement Hydrostor has signed with Baker Hughes underscores the momentum behind our A-CAES technology platform that is able to cost-effectively provide reliability and resiliency to grids around the world,” said Curtis VanWalleghem, Hydrostor co-founder and CEO. “We’re excited to build on our relationship with Baker Hughes as we near construction for our flagship projects and work to expand our project pipeline, as load grows and AI data center infrastructure is being built out globally.”
