<P> As of 2016, the U.S. had a fleet of 160,000 NG vehicles, including 3,176 LNG vehicles . Other countries where natural gas - powered buses are popular include India, Australia, Argentina, Germany, and Greece . In OECD countries, there are around 500,000 CNG vehicles . Pakistan's market share of NGVs was 61.1% in 2010, follow by Armenia with 32%, and Bolivia with 20% . The number of NGV refueling stations has also increased, to 18,202 worldwide as of 2010, up 10.2% from the previous year . </P> <P> Existing gasoline - powered vehicles may be converted to run on CNG or LNG, and can be dedicated (running only on natural gas) or bi-fuel (running on either gasoline or natural gas). Diesel engines for heavy trucks and busses can also be converted and can be dedicated with the addition of new heads containing spark ignition systems, or can be run on a blend of diesel and natural gas, with the primary fuel being natural gas and a small amount of diesel fuel being used as an ignition source . It is also possible to generate energy in a small gas turbine and couple the gas engine or turbine with a small electric battery to create a hybrid electric motor driven vehicle . An increasing number of vehicles worldwide are being manufactured to run on CNG by major carmakers . Until recently, the Honda Civic GX was the only NGV commercially available in the US market . More recently, Ford, General Motors and Ram Trucks have bi-fuel offerings in their vehicle lineup . In 2006, the Brazilian subsidiary of FIAT introduced the Fiat Siena Tetra fuel, a four - fuel car that can run on natural gas (CNG). </P> <P> NGV filling stations can be located anywhere that natural gas lines exist . Compressors (CNG) or liquifaction plants (LNG) are usually built on large scale but with CNG small home refueling stations are possible . A company called FuelMaker pioneered such a system called Phill Home Refueling Appliance (known as "Phill"), which they developed in partnership with Honda for the American GX model . Phill is now manufactured and sold by BRC FuelMaker, a division of Fuel Systems Solutions, Inc . </P> <P> CNG may be generated and used for bulk storage and pipeline transport of renewable energy and also be mixed with biogas, produced from landfills or wastewater . This would allow the use of CNG for mobility without increasing the concentration of carbon in the atmosphere . It would also allow continued use of CNG vehicles currently powered by non-renewable fossil fuels that do not become obsolete when stricter CO2 emissions regulations are mandated to combat global warming . </P>
