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