Can green hydrogen save a coal town and slow climate change?


              A smokestack stands at a coal plant on Wednesday, June 22, 2022, in Delta, Utah. Developers in rural Utah who want to create big underground caverns to store hydrogen fuel won a $504 million loan guarantee this spring. They plan to convert the site of the 40-year-old coal power plant to cleanly-made hydrogen by 2045. (AP Photo/Rick Bowmer)
