Of the more than 23 million NGVs worldwide and 175,000 on U.S. roads, most are buses, refuse trucks and medium-duty fleet vehicles, but manufacturers are now producing several models suitable for consumer use. Also, there are many models of gasoline-powered vehicles which can be converted to operate on CNG.
Our nation has the most extensive natural gas distribution system of any country in the world, making it feasible to install CNG fueling equipment at existing gas stations supplied from existing natural gas lines. There are more than 1,600 NGV fueling stations available now and the number is growing fast. In addition, convenient home refueling with CNG home refueling appliances is already available with more appliances expected on the market soon.
