Baker Hughes Technology to Integrate with Hydrostor’s A-CAES Projects

Last week, Baker Hughes and Hydrostor signed a strategic technology solutions and equity agreement at the 2026 Baker Hughes Annual Meeting in Florence, Italy. The agreement integrates Baker Hughes’ compression, expander, motor, and generator technology with Hydrostor’s advanced compressed air energy storage (A-CAES) solution, including up to 1.4 GW of equipment orders for flagship projects.

“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, 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.”

Baker Hughes has invested in Hydrostor since 2019, with the latest agreement arriving as Hydrostor nears construction on 1.4 GW of A-CAES, power generation, and compression projects in the United States and Australia.

"Increasing pressure on electric grids is making long-duration energy storage an urgent priority,” said Lorenzo Simonelli, Chairman and CEO of Baker Hughes. “Hydrostor's approach offers a low-carbon solution to ensure power reliability across a diverse mix of generation resources. 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.”

Ammonia Production

In late January, Baker Hughes agreed to deliver essential compression and integrated well construction solutions for Wabash Valley Resources’ (WVR) ammonia fertilizer production plant in West Terre Haute, IN—among the first low-carbon plants of its kind in the United States. These technologies will support multiple stages of the clean ammonia value chain, including hydrogen production, CO₂ separation, and permanent sequestration.

The company will supply compression equipment for Honeywell UOP’s hydrogen purification system, in addition to compressors for ammonia and syngas processing under a separate contract with a different customer. Also, Baker Hughes will provide CO₂ injection pumps for permanent geological storage.

WVR’s project will convert an existing gasification facility into a modern clean ammonia plant and, once in operation, it will produce 500,000 tons of ammonia per year while capturing 1.67 million tons of CO₂ annually. Its ammonia production, coupled with carbon capture and storage, will create a more sustainable and reliable domestic fertilizer supply for the U.S. Corn Belt and wider agricultural market.

Kuwait Oil Fields

In December 2025, the Kuwait Oil Co. (KOC) granted Baker Hughes a significant award—via multi-year agreement—to deliver advanced artificial lift systems and related services to improve production in domestic oil and gas fields. The company will supply multiple types of electrical submersible pumps (ESPs), in addition to installation, surveillance, and maintenance services. ESP performance will be optimized by integrating FusionPro intelligent production drive and the Leucipa automated field production solution.

Both FusionPro and Leucipa will improve operational reliability and minimize non-productive time across KOC’s oil and gas fields. This multi-year agreement follows a Q3 award from KOC to supply advanced wireline and perforation technology and services, including Proxima advanced logging services. Proxima was installed to enhance reservoir evaluation, optimize production, and increase recovery.
