Natural Gas Is Often Stored Before It Is Delivered
Natural gas is moved by pipelines from the producing fields to consumers. Because natural gas demand is greater in the winter, it is stored along the way in large underground storage systems, such as old oil and gas wells or caverns formed in old salt beds. The gas remains there until it is added back into the pipeline when people begin to use more gas, such as in the winter to heat homes.
When the gas gets to the communities where it will be used (usually through large pipelines), it flows into smaller pipelines called "mains." Very small lines, called "services," connect to the mains and go directly to homes or buildings where it will be used.
Natural Gas Can Also Be Stored and Transported as a Liquid
When chilled to very cold temperatures, approximately -260°F, natural gas changes into a liquid and can be stored in this form. Because it takes up only 1/600th of the space that it would in its gaseous state, liquefied natural gas (LNG) can be loaded onto tankers (large ships with several domed tanks) and moved across the ocean to other countries. When this LNG is received in the United States, it can be shipped by truck to be held in large chilled tanks close to users or turned back into gas when it's ready to put in the pipelines.
