What is Liquefied natural gas (LNG)?
Liquefied natural gas (LNG) is natural gas converted into a liquid state to more easily transport and store. LNG is created by cooling natural gas to a very low temperature (-162°C or -260°F). Once it is condensed, it takes up less volume than in a gaseous state. LNG is composed primarily of methane, but may also contain other hydrocarbons, such as ethane, propane and butane. LNG often is produced from “stranded” natural gas reserves, i.e., which are far from population centers or transportation infrastructure. The LNG produced in remote areas then can be moved from areas where pipelines or other forms of transportation may not be economically feasible.
