How is natural gas stored?
Natural gas may be stored in a number of ways. It is most commonly stored under ground, under pressure, in three types of facilities. The most commonly used facilities in California are depleted reservoirs in oil and/or gas fields, because they are more available. Aquifers and salt cavern formations are also used under certain conditions. The characteristics and economics of each type of storage site will dictate its suitability for use. Two of the most important characteristics of an underground storage reservoir are its capability to hold natural gas for future use and its deliverability rate. The deliverability rate is determined by the withdrawal capacity of the associated valves and compressors and the total amount of gas in the reservoir. In other states, natural gas is also stored as LNG after the natural gas has been liquefied and placed in aboveground storage tanks.
