As detailed in the paper, "Integrating Clean Energy Technologies with Existing Infrastructure," the Western Energy Hub, near Delta, Utah, sits atop the only known utility-scale "Gulf Coast"-style salt dome in the western U.S., capable of storing gases, including hydrogen and compressed air, that can be drawn upon efficiently and economically to meet variable power requirements. For example, power from renewable sources can be stored as hydrogen and later returned to the grid as electricity in a variety of ways, including as a carbon-free fuel for combined-cycle turbines such as those that will be installed at the adjacent Intermountain Power Project for startup in 2025.
