Utah To Home World’s Largest Underground Hydrogen Storage Project
Mitsubishi Power Americas and Magnum Development are working together on the construction of a 300 GWh underground storage facility in Utah, USA. Hydrogen Industry Leaders looks at how what is said to be the largest underground hydrogen storage project will have an impact on the industry.

Aces Delta, a joint venture between Mitsubishi Power Americas and Magnum Development LLC is planning to build an underground storage project in Utah and it will consist of two caverns with capacities of 150 GWh.

Hydrogen will be generated by an adjacent 840 MW hydrogen-capable gas turbine combined cycle power plant.

Aces Delta said: “The plant will initially run on a blend of 30% green hydrogen and 70% natural gas starting in 2025 and incrementally expand to 100% green hydrogen by 2045,”

It will see US-based contractor WSP USA build the two underground hydrogen storage caverns after it secured an engineering, procurement, and construction management contract (EPCM).

The storage caverns and the power plant together will form the Advanced Clean Energy Storage hub, which is said to be able to convert renewable energy via 220 MW of electrolysers and will produce up to 100 metric tons of green hydrogen per day.
