Liquefied Natural Gas, or LNG, is natural gas in its liquid form. When natural gas is cooled down to minus 259 degrees Fahrenheit (or -161 degrees Celsius), it becomes a clear, colorless, odorless liquid. Natural gas in liquid form, is only one six-hundredth of the volume of its gaseous form, which makes it easier to be stored and transport.
The natural gas is primarily Methane, with low concentrations of other , water, Carbon dioxide, nitrogen, oxygen and some sulfur compounds. During the process known as , the natural gas is cooled down below its boiling point, and in the process removing most of these additional compounds. The remaining gas is primarily methane with only low amounts of other hydrocarbons.
Liquefied natural gas weighs less than half the weight of water so it will float if spilled on water.
