About LNG

Liquefied natural gas, or LNG, is natural gas that has been cooled to minus 260 degrees Fahrenheit, the point at which gas condenses to a liquid. When natural gas is cooled through liquefaction, its volume is reduced by 600 times, which means LNG uses 1/600 of the space required for the same mass of gas -- similar to reducing the volume of a beach ball to the volume of a ping-pong ball -- making it more practical to store and transport.

LNG is stored and transported at a very low (near atmospheric) pressure in double-walled, insulated tanks. The inner tank contains the LNG, while the outer tank contains the insulation and prevents any natural gas vapor from escaping. Once delivered to its destination the LNG is warmed back into its original gaseous state so it can be transported via pipeline to its final destination for distribution to homes and businesses.
