A natural gas vehicle (NGV) utilizes compressed natural gas (CNG) or liquefied natural gas (LNG) as an alternative fuel source. Distinguished from autogas vehicles fueled by liquefied petroleum gas (LPG), NGVs rely on methane combustion, resulting in cleaner emissions due to the removal of contaminants from the natural gas source.
Natural gas vehicles (NGVs) are popular in regions or countries where natural gas is abundant. Widespread use began in the Po River Valley of Italy, and later became very popular in New Zealand by the eighties, though its use has declined. [73] Buses powered with CNG are common in the United States.
Compressed natural gas (CNG) is a fuel gas mainly composed of methane (CH 4), compressed to less than 1% of the volume it occupies at standard atmospheric pressure. It is stored and distributed in hard containers at a pressure of 20–25 megapascals (2,900–3,600 psi; 200–250 bar), usually in cylindrical or spherical shapes.
CNG vehicles can use both renewable CNG and non-renewable CNG. [61] Conventional CNG is a fossil fuel. New technologies such as horizontal drilling and hydraulic fracturing to economically access unconventional gas resources, appear to have increased the supply of natural gas in a fundamental way. [62]
Alternative fuel vehicles: Currently the only pre-approved alternative fuel vehicle is the Honda Civic GX, which runs on compressed natural gas (CNG), a fossil fuel that burns cleaner than standard gasoline. [12] Currently the standard credit for a qualified alternative fuel vehicle is $4,000.

Germany had to turn to liquefied natural gas, or LNG, super-cooled and imported by ship from Qatar and the U.S. LNG costs more than pipeline gas. Electricity now costs industrial users in Germany an average of 20.3 euro cents per kilowatt hour, according to a study the research firm Prognos AG prepared for the Bavarian Industry Association.
A motor fuel is a fuel that is used to provide power to the engine of motor vehicles — typically a heat engine that produces thermal energy via oxidative combustion of liquid or gaseous fuel and then converts the heat into mechanical energy through reciprocating pistons or gas turbines.
