Compressed Natural Gas (CNG) saves money compared to conventional fuels. Consumers who are natural gas customers also have the option of refueling at home with a natural gas home refueling appliance, which uses a time-fill system of filling a tank overnight.
The process for refueling is almost identical to the process used at local gasoline stations. Most public CNG stations accept credit cards at the dispenser and the filling time is similar to using a gasoline pump.
Most stations have no attendants on duty. You will first need to be trained on the use of the CNG operations.
