A Natural gas vehicle or '''NGV''' is a Vehicle that uses Compressed Natural Gas (CNG) or, less commonly, Liquified Natural Gas (LNG) ) as a clean alternative to other Automobile fuels. Worldwide, there are roughly 4 million NGVs As Of 2004 , with the largest number of NGVs in Argentina , Brazil , and Pakistan . They are also popular in Italy and Germany . While existing gasoline-powered vehicles may be converted to CNG, an increasing number of vehicles worldwide are being manufactured to run on CNG. For example, in Klang Valley , Malaysia taxis had converted theirs car to NGV, greatly reducing the cost of operation. However, NGV refill stations are scarce, so cab drivers need to wait in long queues to refill. Chemical composition and energy content Chemical composition The primary component of Natural Gas is Methane ( C H 4), the shortest and lightest Hydrocarbon molecule. It may also contain heavier gaseous hydrocarbons such as Ethane ( C 2 H 6), Propane ( C 3 H 8) and Butane ( C 4 H 10), as well as other gases, in varying amounts. Hydrogen Sulfide ( H 2 S ) is a common contaminant, which must be removed prior to most uses. Energy content Combustion of one Cubic Meter yields 38 MJ (10.6 kWh). Natural gas has the highest energy/carbon ratio of any fossil fuel, and thus produces less carbon dioxide per unit of energy. Storage and transport Transport The major difficulty in the use of natural gas is Transport ation. Natural gas Pipelines are economical, but are impractical across oceans. Liquefied natural gas ( LNG ) Tankers are also used, but have higher cost and safety problems. Storage Natural gas is often stored as CNG, in hard containers at high pressure. SEE ALSO EXTERNAL LINKS
