HOUSTON—At more than double the height of The Empire State building belowground, salt caverns about as tall as the Eiffel Tower are capable of storing up to about 4,000 tons of hydrogen.

“This is why you go underground,” said Claire Behar, chief commercial officer for Hy Stor Energy, the company that plans to develop what could be the United States’ largest green hydrogen hub in Mississippi. “You can really get to that scale, and it’s this availability of supply that is needed to transition off of fossil fuels to renewable hydrogen.”

Energy experts are bullish on hydrogen, touting its ability to decarbonize high CO2-emitting sectors such as steel manufacturing, maritime and heavy-duty transport where direct electrification isn’t necessarily the most cost-efficient solution.
