Mitsubishi to Switch US Coal Plant to Gas/Hydrogen Mix

Japan's Mitsubishi Hitachi Power System (MHPS) has received a contract to supply two M501JAC power trains for the Intermountain Power Plant (IPP) in Delta, Utah, from the Intermountain Power Agency, MHPS' US division said in a statement on March 10.

The power trains will include gas turbines, steam turbines and heat recovery steam generators and auxiliary equipment. MHPS will service the plant under a 20-year agreement. The trains will enable the station to switch from coal to gas and eventually renewable hydrogen. The goal is to run the 840-MW plant entirely on this hydrogen by 2045.

The transition will begin in 2025, after which the turbines will use a mix of 70% and 30% hydrogen, emitting 75% less carbon than the current coal-fired capacity. The share of hydrogen will be systematically raised to 100% between 2025 and 2045.
