The largest underground hydrogen storage project in the world – pv magazine International

Mitsubishi Power Americas and Magnum Development are set to begin construction of a 300 GWh underground storage facility in the US state of Utah. It will consist of two caverns with a capacity of 150 GWh, to store hydrogen produced by an adjacent 840 MW hydrogen gas turbine combined cycle power plant.

Aces Delta, a joint venture between Mitsubishi Power Americas and Magnum Development LLC, plans to construct a 300 GWh underground storage project in Delta, Utah.

Advanced Clean Energy Storage I, LLC recently secured a $504.4 million loan guarantee from the U.S. Department of Energy’s (DOE) Office of Loan Programs for the construction of the storage facility. The project will store hydrogen generated by the Intermountain Power Agency’s renewed IPP project – an 840 MW gas turbine combined cycle power plant located in the region.

“The plant will initially operate on a mix of 30% green hydrogen and 70% natural gas starting in 2025 and will gradually expand to 100% green hydrogen by 2045,” Aces Delta said in a statement. a statement.

US contractor WSP USA has been awarded an engineering, procurement and construction management (EPCM) contract to build the two underground hydrogen storage caverns, each with a capacity of 150 GWh.

“This stored green hydrogen becomes an energy reserve that can be released to produce fuel for power generation at any time,” WSP USA said.

The storage caverns and power plant will form the Advanced Clean Energy Storage hub, which Aces Delta says will convert renewable energy through 220 MW of electrolysers to produce up to 100 metric tons of green hydrogen per day. Development of the project began in May 2019.

“Central Utah is the perfect location for this project, and Utah is a business-friendly state for projects like this,” said Magnum CEO Craig Broussard. “The Magnum site adjacent to the intermountain power project is positioned to take full advantage of existing regional power grid connections, fully developed transmission infrastructure, sufficient solar and wind development capacity, a hand -skilled labor currently moving away from coal and of course the unique salt dome opportunity.”

Magnum Development also has a domain-grade salt formation in the western United States and five operational salt caverns for liquid fuel storage.
