Natural gas vehicle Natural gas vehicle A natural gas vehicle (NGV) is an alternative fuel vehicle that uses compressed natural gas (CNG) or liquefied natural gas (LNG). Natural gas vehicles should not be confused with vehicles powered by LPG (mainly propane), which is a fuel with a fundamentally different composition. In a natural gas powered vehicle, energy is released by combustion of essentially Methane gas () fuel with Oxygen () from the air to carbon dioxide () and water vapor () in an internal combustion engine. Methane is the cleanest burning hydrocarbon and many contaminants present in natural gas are removed at source.
Natural gas term natural gas distribution contracts are signed in cubic meters, and LNG contracts are in metric tonnes. The LNG and LPG is transported by specialized transport ships, as the gas is liquified at cryogenic temperatures. The specification of each LNG/LPG cargo will usually contain the energy content, but this information is in general not available to the public. In the Russian Federation, Gazprom sold approximately of natural gas in 2008. In 2013 they produced of natural and associated gas. Gazprom supplied Europe with of gas in 2013. In August 2015, possibly the largest natural gas discovery in history was made
