Mitsubishi Hitachi Power Systems (MHPS) and Magnum Development have unveiled the Advanced Clean Energy Storage (ACES) project in central Utah, US. The ACES project is the largest project of its kind in the world and will develop 1GW of clean energy storage.

The project will focus on the deployment of four energy storage technologies at utility scale in order to ensure a decarbonised future for the power grid of the Western US. The technologies include renewable hydrogen, compressed air energy storage, large scale flow batteries and solid oxide fuel cells.

MHPS Americas president and CEO Paul Browning said: “For 20 years, we’ve been reducing carbon emissions of the US power grid using natural gas in combination with renewable power to replace retiring coal-fired power generation.

“In California and other states in the western United States, which will soon have retired all of their coal-fired power generations, we need the next step in decarbonisation. Mixing natural gas and storage, and eventually using 100% renewable storage, is that next step.

“ACES project will focus on the engineering, finance, construction, and operation of the facilities, which will be located in Millard County, Utah.”

“The technologies we are deploying will store electricity on time scales from seconds to seasons of the year.”
