Refueling

An extensive pipeline infrastructure already supplying homes for heating and cooking can be fitted with a compact CNG refilling station that refills half a gallon per hour. A public access CNG refilling station must be used for a fast five minute refill. Note: Since CNG is in vapor and not liquid form, a gasoline gallon equivalent (GGE) is used to compare the energy of CNG to gasoline. It takes approximately 126.67 cubic feet or 5.7 pounds of CNG to equal the energy content of one gallon of gasoline.
