Abstract
The present disclosure is directed toward a system and a method for storing gas. The system for storing gas comprises a salt formation, an overburden, an underburden, a salt cavern within the salt formation, a sorbent within the salt cavern, and a well traversing the surface that connects the surface with the salt cavern. The method for storing gas comprises several steps. A dissolving fluid comprising water is injected into a salt formation to produce a brine and a salt cavern within the salt formation. The brine is then removed from the salt cavern. A sorbent is then placed within the salt cavern before gas is injected into the salt cavern.
