Plans to build an underground hydrogen storage plant in Utah

A 300 GWh underground hydrogen storage plant in Utah, USA is about to start construction. The project is being developed by Mitsubishi Power Americas and Magnum Development. Recently, the Office of Loan Programs of the Department of Energy (DOE) provided a loan guarantee of US$504.4 million for the development of the project. Advanced Clean Energy Storage I, LLC is the beneficiary of the loan.

The underground hydrogen storage plant in Utah will include two caverns with a capacity of 150 GWh to store hydrogen in two huge salt caverns. The hydrogen will be produced by the Intermountain Power Agency’s renewed IPP project. The latter is an 840 MW gas turbine combined cycle power plant nearby.

The plant will initially run on a mix of 30% green hydrogen and 70% natural gas starting in 2025. That’s according to a statement from Aces Delta. Additionally, the release notes that the facility will slowly expand to 100% green hydrogen by 2045.

The underground hydrogen storage plant in Utah will be built under an engineering, procurement and construction management (EPCM) contract. The contract was awarded to the American contractor WSP USA. The latter is a Canadian company providing management and consulting services in the built and natural environment.

The stored green hydrogen turns into an energy reserve that can be released at any time to fuel power generation. The underground hydrogen storage plant in Utah, in addition to the storage caverns, constitutes the Advanced Clean Energy Storage hub. The plant will use 220 MW of electrolysers to convert renewable energy into up to 100 metric tons of green hydrogen each day.

Development of the project began in May 2019.
