ACES are Wild

Largest U.S. energy storage project yet confirmed with DOE blessing

The U.S. Department of Energy’s (DOE) Loan Programs Office announced this week that it has issued a conditional commitment to Advanced Clean Energy Storage I, LLC, and Mitsubishi Power Americas, Inc. and Magnum Development, LLC, and Haddington Ventures, LLC, for up to $504.4MM in debt financing for the Advanced Clean Energy Storage Project, expected to be the world’s largest industrial green hydrogen production and storage facility. The project is planned for Delta, Utah, about 2 hours south of Salt Lake City.

“We are unbelievably excited to reach this important milestone, not just for our hub, but for the hydrogen industry as a whole,” said Michael Ducker, Senior Vice President of Hydrogen Infrastructure for Mitsubishi Power. Tweet this

The ACES (with all the acronyms out there, you'd think they would pounce on this one) project is slated to replace the existing Intermountain Power Plant in Delta, by approximately 2025, and intends to be a hub for hydrogen power. The hub was first announced in May 2019, and is now in the final stages of debt and equity closing.

“We are unbelievably excited to reach this important milestone, not just for our hub, but for the hydrogen industry as a whole,” said Michael Ducker, Senior Vice President of Hydrogen Infrastructure for Mitsubishi Power Americas and President of Advanced Clean Energy Storage I. “Equally rewarding is having spent the past year partnering and working with such a forward-thinking and incredibly talented team from the Intermountain Power Agency to trail blaze this market leading facility. We are honored to be sharing this industry moment with them along with all of our world-class partners joining this effort.”

The hub will initially be designed to convert renewable energy through 220 MW of electrolyzers to produce up to 100 metric tonnes per day of green hydrogen, which will then be stored in two massive salt caverns each capable of storing 150 GWh of energy. Financed with support from the DOE loan guarantee, this facility will supply hydrogen feedstock to the Intermountain Power Agency’s (IPA) IPP Renewed Project — an 840 MW hydrogen capable gas turbine combined cycle power plant — that will initially run on a blend of 30 percent green hydrogen and 70 percent natural gas by volume starting in 2025 and will increase to 100 percent by 2045.

“The IPP Renewed Project is committed to helping the region meet its carbon targets by utilizing green hydrogen as a tool to integrate affordably and reliably with the significant build-out of renewables. The scale, experience, and collaboration offered by the Advanced Clean Energy Storage hydrogen hub made their team the ideal partner for us to work with as we realize our vision towards 100% green hydrogen at the site,” said Greg Huynh, Operating Agent, IPA.

Multiple industry-leading entities are also involved in the hub, which broke ground this Spring, including:

  • Black & Veatch, an industry leader in engineering, procurement, and construction which will provide EPC services for the energy conversion facility and will draw on its extensive experience building complex energy infrastructure projects to construct the hydrogen production facilities.

  • Mitsubishi Power, an industry leader in technology offerings, will provide the hydrogen equipment integration including the 220 MW of electrolyzers, gas separators, rectifiers, medium voltage transformers, and distributed control system.

  • NAES Corporation, one of the energy industry’s largest independent providers of operations, maintenance, and repair services, will initially provide the O&M services for the plant and will oversee the current projected team of 20 plant-related personnel.

  • Utah School and Institutional Trust Lands Administration, a subdivision of the State of Utah, leases the site and utilizes revenue generated from the hydrogen hub to benefit Utah schools.

  • WSP, a global leader in engineering that develops creative, comprehensive and sustainable solutions to help communities thrive, will provide EPC Management services for the development of two large salt cavern storage facilities. WSP has been developing underground storage facilities since the 80s and has developed over 200 salt caverns for top tier midstream companies.

“The Advanced Clean Energy Storage Project is well on its way to achieving its goal in the creation of a world-class green hydrogen hub,” said Craig Broussard, CEO of the joint venture. “Through our network of partners, we have the potential to provide low-cost green hydrogen to verticals in addition to power, including refineries, heavy industrials, and the transportation sector.”

While this conditional commitment demonstrates the Department’s intent to finance the project, several steps remain, and certain conditions must be satisfied before DOE issues a loan guarantee.

The hub is actively seeking partners to bring green jobs and green hydrogen to support rural Utah and greater decarbonization across industries. For more information, visit
