Abstract
The present disclosure is directed toward a method for storing methane. The method for storing methane 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 methane is injected into the salt cavern.
