The ACES project for green hydrogen and electricity production is currently under construction in Utah: https://www.deseret.com/2022/5/9/23046910/green-hydrogen-energy-advanced-clean-energy-storage-project-utah-politics-renewables-delta-ipp https://www.deseret.com/2022/5/9/23046910/green-hydrogen-ene... The project will take that excess solar and wind capacity and through a process called alkaline electrolysis it will separate oxygen and hydrogen from water through 220 megawatt electrolyzers, producing up to 110 tons of hydrogen a day. It is called green hydrogen because it is derived from renewable power sources. ... The other “wow” factor of the project is the salt cavern storage reservoirs. “Those salt caverns will be the largest single storage site for hydrogen, globally,” Ducker said. He pointed out that the battery storage capacity across the United States sits at two gigawatt hours via lithium ion batteries. The Utah project will have storage for 300 gigawatt hours of energy. ... The salt domes for storing the hydrogen will be 3,500 feet underground and will be as deep as the Empire State building is tall — about 1,500 feet. Ducker said the caverns will enable long duration storage of energy and prevent monthly curtailments of solar and wind energy.
