Abstract
A novel system and method for storing hydrogen in a salt cavern and supplying therefrom is provided. Hydrogen product withdrawn from a hydrogen pipeline may be chilled prior to being introduced into a cavern in order to cool at least a portion of the walls of the salt cavern so that one or more layers of the localized portion of the walls attains a stabilized state whereby contaminant release from the walls is suppressed. The present invention anticipates and strategically plans for contaminant intrusion form a salt cavern in order to reduce the degree of contaminant intrusion from a salt cavern while also allowing the stored hydrogen to have more absorption capacity for water vapor by virtue of entering the salt cavern in a sufficiently drier state. Alternatively, or in addition thereto, a crude hydrogen stream may be withdrawn from the cavern and chilled prior to introducing to the hydrogen pipeline.
