"Domestically produced and readily available to end-users through the existing utility infrastructure, natural gas has become increasingly popular as an alternative transportation fuel. Natural gas is also clean burning and produces significantly fewer harmful emissions than reformulated gasoline. Natural gas can either be stored on board a vehicle in tanks as compressed natural gas (CNG) or cryogenically cooled to a liquid state, liquefied natural gas (LNG)." - www.afdc.doe.gov
