Conversion of 1,800MW Intermountain coal plant in Utah to 840MW gas-hydrogen facility moving forward

S&P Global Market Intelligence ($):

The Intermountain Power Agency, owner of the 1,800-MW coal-fired Intermountain power plant in Delta, Utah, has picked Black & Veatch Corp. as the chief engineering company to oversee the facility’s conversion into an 840-MW combined-cycle facility that will run initially on a mix of natural gas and hydrogen and will ultimately operate on hydrogen alone, the Kansas-based engineering and consulting firm announced June 3.

The municipal power agency’s selection of Black & Veatch follows its recent order of advanced turbines from Mitsubishi Hitachi Power Systems Americas Inc., which has a long track record of working with hydrogen-fired turbines at industrial sites, for the new plant. The two single-shaft combined-cycle units are designed to run on a mix of 30% hydrogen and 70% natural gas upon completion in 2025, increasing to 100% hydrogen by 2045.

Mitsubishi Hitachi is also working with Magnum Development LLC to create a renewable hydrogen generation and storage facility adjacent to the plant, part of a planned 1,000-MW multitechnology energy storage complex. The project partners aim to use excess renewable energy from across the Western U.S. to generate “green hydrogen” via electrolysis and store it in an existing underground salt dome beneath the power plant.

The Los Angeles Department of Water and Power, which operates the Intermountain facility and is the largest buyer of its power, intends to use the converted plant to help meet California’s target to completely decarbonize all retail power sales in the state by 2045. Several other municipal utilities in California and Utah that currently purchase power from the coal-fired plant have agreed to purchase power from the re-powered project.

“Using renewable energy in the form of green hydrogen will help California meet its zero-carbon state goals for 2045,” Brian Sheets, project manager with Black & Veatch’s power business, said in a statement. “The location in central Utah is also significant because the local geology provides the capability to store excess hydrogen in large underground caverns, and existing regional transmission infrastructure will serve as a hub for collecting and transporting renewable energy to southern California.”
