Liquefied Natural Gas


LNG is a clear, colorless liquid made by cooling natural gas to about -163 degrees centigrade. Natural gas is composed mainly of methane and ethane, and can be used as a fuel. It is extracted from oil and gas wells, and is also found in wetlands and from anthropogenic sources that include landfills and agricultural operations. When cooled and liquefied, it takes up only a tiny fraction of the volume of the gaseous form, so can be transported efficiently.
