Liquefied natural gas is natural gas that has been transformed into a liquid state. This is done for storage and transportation purposes. It takes up about 1/600th the volume of natural gas in the gaseous state. The (volume-based) energy density of LNG is approximately 2.4 times greater than that of CNG which makes it economical to transport natural gas by ship in the form of LNG. The energy density of LNG is comparable to propane and ethanol but is only 60 percent that of diesel and 70 percent that of gasoline.
