About 1,000 to 3,000 metric tons of hydrogen can be withdrawn from a salt cavern per day

The amount of hydrogen that can be withdrawn from a salt cavern in a day depends on various factors, including the size of the cavern, the pressure at which the hydrogen is stored, and the specific engineering and infrastructure in place. Generally, a well-designed salt cavern can facilitate the withdrawal of substantial quantities of hydrogen.

On average, large-scale salt caverns can typically withdraw around 1,000 to 3,000 metric tons of hydrogen per day.1 This capacity allows for significant flexibility in managing energy supply, particularly in emergencies or during peak demand periods. The specific withdrawal rate can vary based on the cavern's characteristics and the technological setup used for extraction and distribution.
