Liquefied natural gas (LNG) - the newest type of fuel produced by the liquefaction of natural gas using cryogenic technology. Liquefied natural gas for their operational, economic and environmental characteristics favorably with other fuels. First, CNG offers all the benefits of natural gas. Second, the concentration of energy per unit volume of LNG is almost 600 times greater than in the gaseous form. In addition, the storage and use of liquefied natural gas is much safer than storing compressed natural gas or liquefied petroleum gas.
