The abbreviation LNG stands for “Liquefied Natural Gas”. LNG is produced by cleaning and liquefying natural gas (mainly methane) by cooling it to a temperature of -162°C, at nearly atmospheric pressure.

In liquid form, the energy density of natural gas is 600 times higher than in gaseous form. Therefore transport is easier and it needs less tank volume. Its energy density is about 15 to 21% higher than the energy density of kerosene or diesel fuels, so less weight is needed to cover the same distance.

LNG can be used as fuel for vehicles and aircrafts, as well as for power and heat generation.

Extensive description of the LNG world industry, trade routes & contracts, exports sources & imports terminals, quantities & qualities is reported in the LNG Industry 2010 Report of the GIIGNL (The International Group of LNG Importers), publically available at:
