Liquefied Natural Gas
Liquefied Natural Gas (LNG) is natural gas that has been cooled and condensed into liquid form. Natural gas is liquefied for the purpose of making it easy to store or transport long distances where pipelines can't be installed (i.e. across oceans). Liquefied natural gas only takes up about 600 times less space than natural gas in it's gaseous state. In order to liquefy natural gas, the natural gas must be cooled to to approximately −162°C (−260°F). LNG is stored at low pressure close to atmospheric pressure.
