LNG - Liquefied Natural Gas

LNG - Liquefied natural gas (LNG) is natural gas cooled to approximately -260F (-162C) (+111K) to achieve a liquid state for transport and storage. Natural gas volume in the gaseous state is roughly 600 times larger than the liquid state, making transport impractical. Liquefying natural gas, a process developed in the 19th century, is a means to economically transport natural gas long distances where gas pipelines are not feasible.

In a liquid state natural gas is shipped in special tankers to worldwide terminals, where it is returned to its gaseous state and transported by pipeline to distribution companies, power plants, and other industrial customers.
