The largest green hydrogen project in the US is now 95% complete

The ACES Delta green hydrogen project in Utah, which is expected to become the largest green hydrogen facility in the United States, has reached about 95% completion and has begun commissioning activities, including the initial production of hydrogen molecules. Although the project has experienced delays from its original timeline, it is now moving closer to full commercial operation. Backed by major partners including Chevron and Mitsubishi Power, the project features a large 220MW electrolyze system that uses renewable electricity to produce green hydrogen. This hydrogen is a key component of a broader clean energy strategy aimed at supporting grid reliability and reducing carbon emissions. Once fully operational, the facility will produce hydrogen that can be stored in massive underground salt caverns, allowing energy to be stored for long periods and used when electricity demand is high or renewable generation is low. The stored hydrogen is intended for use at the Intermountain Power Agency’s IPP Renewed Project, where it will initially be blended with natural gas and eventually used to support power generation with significantly lower emissions. By combining renewable energy, large-scale hydrogen production, and long-duration storage, the ACES Delta project is positioned as a critical infrastructure development for the US energy transition and a model for future green hydrogen projects nationwide.
