LNG is Liquefied Natural Gas, and quite simply, it is natural gas in its liquid form. It is a clear, colourless, odorless and non-toxic liquid. The liquefaction of natural gas allows for the convenient transportation and storage of natural gas. When the temperature of natural gas is reduced to -161 degrees Celsius, at atmospheric pressure, the gas changes from a vapour to a liquid. The gas shrinks to a fraction of its original volume – one six hundredth. LNG is less than half as dense as water. It is stored as a liquid for transportation, and once it reaches its destination, it is warmed back to its gaseous state, when needed.
