Mitsubishi Hitachi Power Systems (MHPS) and Magnum Development plan to develop the Advanced Clean Energy Storage (ACES) project, a 1,000 MW energy storage project in Utah (United States).
The ACES project would include four types of energy storage technologies - renewable hydrogen, compressed air energy storage, large scale flow batteries and solid oxide fuel cells - to store excess renewable power generation in western states. It would be located in Millard County, Central Utah, near the Intermountain Power Project, a 1,640 MW coal-fired power plant, and would then use its existing power transmission infrastructure.
Magnum Development already owns and operates five salt caverns in the western United States and is developing compressed air energy storage and renewable hydrogen storage options. MHPS is also working on hydrogen-fired gas turbines, compressed air storage, solid oxide fuel cells and battery storage technology; this ACES project would fit into the group's strategy to use 100% renewable hydrogen as a fuel source, enabling gas turbines to generate power without emitting CO2.
