Mitsubishi Hitachi Power Systems and Magnum Development plan to develop 1,000 megawatts of renewable energy storage in central Utah. The companies say that the initiative will be the world’s largest project of its kind.
Called the Advanced Clean Energy Storage (ACES) project, it will deploy four types of energy storage technologies at utility scale, which include renewable hydrogen, compressed air energy storage, large-scale flow batteries, and solid oxide fuel cells.
Mitsubishi Hitachi Power Systems (MHPS) developed gas turbine technology that enables a mixture of renewable hydrogen and natural gas to produce power, the company explained. “The MHPS technology roadmap aims to use 100% renewable hydrogen as a fuel source, which will allow gas turbines to produce electricity with zero carbon emissions.”
Based in Holladay, Utah, Magnum Development owns and controls the only known domal-quality salt formation — called Gulf Coast style — in the Western United States.
“With five salt caverns already in operation for liquid fuels storage, Magnum is continuing to develop compressed air energy storage and renewable hydrogen storage options,” the company said. Their site is located adjacent to the Intermountain Power Project, a large coal-fired power plant in the state. This means that the Magnum site can integrate seamlessly with the Western US power grid using existing infrastructure, according to the company.
“Magnum has the below-ground technologies necessary to store energy at utility scale while MHPS has the above-ground technologies such as hydrogen-fired gas turbines, compressed air storage, solid oxide fuel cells, and battery storage technology to supply electricity at grid scale,” said Craig Broussard, CEO of Magnum. “With the ACES initiative, we will dramatically accelerate the vision of a western renewable energy hub that we launched over a decade ago.”
The project received support from Utah Governor Gary Herbert, who said that “Utah continues to set the standard among states for driving next-generation solutions to market.”
According to Magnum and MHPS, the ACES project will engineer, finance, construct, own, and operate facilities that will be located in Millard County, Utah. The companies expect to invite more strategic and financial partners to participate in the project in the near future.
