Construction on the ACES Delta green hydrogen project in Utah is 95% complete and commissioning has begun, according to media reports. It would be one of the largest green hydrogen production and storage facilities in the U.S. once operational.
Located in Delta, UT, the site would have 220 MW of electrolysis capacity powered by renewable energy. The project would enable utility- and industrial-scale green hydrogen production and also support the Intermountain Power Agency’s IPP Renewed Project — an 840-MW hydrogen-capable combined-cycle power plant that would initially be capable of running on a blend of 70% natural gas and 30% hydrogen, potentially expanding to 100% hydrogen by 2045. Hydrogen produced at the site would be stored in underground salt-dome caverns. The project received a $504.4 million loan guarantee from the U.S. Department of Energy (DOE) in 2022.
The power plant will replace an existing 1,800-MW coal-fired power plant, which stopped producing power just before Thanksgiving. The coal units will remain operational while the state looks for new customers for their power, as state law prohibits decommissioning work on the units. The units had been running at low capacities for several years due to a lack of demand, the IPA said.
Chevron acquired a majority stake in the project, a joint venture with Mitsubishi Power Americas, in 2023.
