Magnum History

Magnum Development, LLC has defined the salt formation’s extent and characteristics, and has secured key assets (land, minerals, water, etc.) that can be used in the development of multiple projects. Resources committed to date have significantly de-risked both site development and the creation of salt storage caverns—thus expediting and de-risking future business development. Magnum, on its own and through joint ventures, continues to own, control, and develop this site—the Western Energy Hub—the only known “Gulf Coast” style domal-quality salt formation in the Western United States.

• Site viability was proven with the development, commercialization, and sale by Magnum in 2014 to NGL Energy Partners LP and then later sold to Sawtooth Caverns, which operates natural gas liquid storage at the site.
• In 2019, Magnum entered into a joint venture with Mitsubishi Power Americas—ACES Delta, LLC (see ACES-Delta.com)—to develop the world’s largest green hydrogen production and storage facility. This project will store utility-scale hydrogen produced from renewable energy in the on-site salt dome caverns that can be drawn upon to supply clean energy when wind and solar resources cannot meet market demand.
• On September 12, 2023, Chevron U.S.A. Inc., through its Chevron New Energies division, announced it has closed a transaction with Haddington Ventures to acquire 100% of Magnum Development, LLC (Magnum Development) and thus a majority interest in ACES Delta, LLC (ACES Delta), which is a joint venture between Mitsubishi Power Americas, Inc. (Mitsubishi Power) and Magnum Development. ACES Delta is developing the Advanced Clean Energy Storage project in Delta, Utah.
