The conversion takes place by cooling the  gas to approximately -162C (-260F). This process creates a clear, colourless, non-toxic liquid that can be transported from areas with a large supply of natural gas to areas that demand more natural gas.

In its liquid state, natural gas takes up 1/600th of the space ie natural gas is shrunk by 600 times. This makes it much easier to ship and store when pipeline transport is not feasible. 

As world energy consumption increases, experts anticipate that the LNG trade will grow in importance.
