| 20090010714 | LNG RECEIVING TERMINAL THAT PRIMARILY USES COMPENSATED SALT CAVERN STORAGE AND METHOD OF USE - In the past, “compensated” salt caverns have operated with a compensating liquid, such as brine to displace a stored liquid, such as crude oil, when the stored liquid is needed on the surface. Virtually all of the stored liquid in a compensated salt cavern can be expelled from the salt cavern when it is filled with the compensating liquid. In the past, “uncompensated” salt caverns have been used to store gases, such as natural gas. Uncompensated caverns operate without any compensating liquid; instead they rely on pressure. Some of the stored gas (cushion gas) must always be left in an uncompensated salt cavern. This invention breaks with convention and uses a compensating liquid in a salt cavern to store gases which is a technique believed to be previously unknown. “Cushion gas” is not required because the compensating liquid displaces virtually all of the gas in the salt cavern. | 01-08-2009 |

| 20160016210 | SUBSIDENCE CONTROL SYSTEM - A method of maintaining structural integrity of a subsiding earthen fluid containment structure is disclosed and comprises forming a lined containment infrastructure including a convex bulged crown portion, floor portion and sidewall portions which enclose a municipal waste material within an enclosed volume such that fluid flow from the lined containment compound is restricted. The bulged crown flattens, thickens and diminishes in surface area during subsidence of the municipal waste material as fluid is removed. The bulged crown is shaped to avoid tensile stresses which may otherwise result in breach or failure of lined containment during subsidence. Further, the lined containment structure can include an inner insulative layer and an outer impermeable seal layer having unique contributions as described in more detail herein. | 01-21-2016 |
| 20160046443 | SYSTEM FOR OPERATING A HYDROGEN STORAGE SALT CAVERN - A novel system for operating a hydrogen storage cavern is provided.

| 20160060038 | SYSTEM AND METHOD FOR TREATING HYDROGEN TO BE STORED IN A SALT CAVERN AND SUPPLYING THEREFROM - 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 Hydrogen product withdrawn from a hydrogen pipeline may be chilled prior to being introduced into a cavern in order to cool at least a portion of the walls of the salt cavern so that one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. | 03-03-2016 |
