What ACES Delta does

ACES Delta, LLC is a joint venture developing the Advanced Clean Energy Storage site in Delta, Utah — a first-of-kind facility designed to convert, store, and deliver green hydrogen at utility and industrial scale. The company was formed in 2019 between Mitsubishi Power Americas and Magnum Development (founded by Craig Broussard and Rob Webster), and in September 2023 Chevron U.S.A. Inc., through its Chevron New Energies division, acquired a majority interest by purchasing 100% of Magnum Development from Haddington Ventures. The site uses 220 MW of electrolyzers to convert water into green hydrogen using excess renewable electricity, then stores the hydrogen in two subterranean salt dome caverns — each holding approximately 5,500 metric tonnes of working capacity and 150 GWh of dispatchable energy, totaling more than 300 GWh — capitalizing on a Gulf-Coast-style domal salt formation described as the only known such formation in the western United States.

The technology stack pairs electrolyzers, salt cavern storage, and hydrogen-capable gas turbine integration to enable seasonal energy shifting at durations measured in months rather than hours. Production capacity is approximately 100 metric tonnes per day of green hydrogen, supporting Intermountain Power Agency's 840 MW IPP Renewed Project, which will run on 30% hydrogen initially and scale to 100% by 2045. Major capital partners include the U.S. Department of Energy, which closed a $504.4 million loan guarantee in June 2022 — its first renewable energy loan in over a decade — alongside $650 million in equity being secured through Haddington Ventures' Equity Syndication Program. EPC partners Black & Veatch (energy conversion facility) and WSP (salt cavern development) are executing the build, while NAES Corporation will run O&M with a projected 20-person operations team.

ACES Delta's business model is anchored on long-term offtake agreements with utilities, industrial manufacturers, and transportation operators in the Western US. Revenue streams under development include green hydrogen sales to power generation (e.g., IPA as the primary anchor offtake), long-duration energy storage services for utilities and grid operators enabling seasonal shifting, and renewable oxygen as a by-product of electrolysis. Distribution is via direct grid integration to the Western US power grid, connection to the interstate gas transmission system, and highway/rail transport for liquefied hydrogen deliveries. The project broke ground in 2022 and is expected to be the world's largest industrial green hydrogen production and storage facility once commissioned, though it remains pre-revenue with construction ongoing.

Core offering

ACES Delta develops and operates the Advanced Clean Energy Storage facility in Delta, Utah. It converts excess renewable electricity into green hydrogen via 220 MW of electrolyzers, stores the hydrogen in underground salt dome caverns offering over 300 GWh of dispatchable energy, and delivers the hydrogen on demand to power generators, industrial users, and transportation customers. The company monetizes through long-term hydrogen offtake contracts and long-duration energy storage services.

Product overview

ACES Delta operates a single integrated facility, the Advanced Clean Energy Storage Site, which provides an end-to-end solution for green hydrogen energy. The facility captures excess renewable energy during off-peak hours to power electrolyzers that convert water to green hydrogen, stores the hydrogen in two massive underground salt caverns capable of storing over 300 GWh of dispatchable energy, and delivers the hydrogen to fuel hydrogen-capable gas turbines and industrial applications. The site will initially convert over 220 MW of renewable energy to produce up to 100 metric tonnes per day of green hydrogen, supporting the Intermountain Power Agency's 840 MW IPP Renewed Project.
