Abstract

Embodiments are directed to storing, providing, and using hydrogen, helium, or carbon dioxide in a natural hydrogen storage layer or a depleted natural hydrogen storage layer. The hydrogen storage layer can be connected to a hydrogen production system, and hydrogen from the hydrogen production system can be injected into the hydrogen storage layer. The injected hydrogen can be extracted as needed for energy production, for chemical synthesis, or as a feedstock.
