Fueling Your NGV
There are many different natural gas fueling options for NGVs. You can fill up at a public station, just like you do with your gasoline vehicle. Some stations are owned by fleet operators, others are operated by retailers that require a proprietary card to access the fueling dispensers known as a "card lock". Another fueling option is a small home refueling appliance (HRA) such as Fuelmaker Corporation's Phill unit.
Natural gas delivered to you by PG&E is measured in "standard cubic feet", (a measurement of volume), and then converted into "therms". If you are filling up at home using an HRA unit, you will be billed in therms. If you fill up at one of the many available public stations, the unit measurement is GGE or "gasoline gallon equivalent". The national gasoline gallon equivalent conversion factor is 1.276 therms = 1 GGE.
A natural gas Home Refueling Appliance (HRA) is designed to fill cars and pickups through "time fill". It can be installed either in a garage, a carport, or outdoors. Typically, it is a small, wall-mounted unit designed for use with either 120 or 240 volts, and a simple connection to your residential natural gas supply line.
On average, it will take 5-8 hours to fill your tank after approximately 50 miles of driving. Usually the HRA is hooked up to the car and left on overnite to perform the "time fill", unlike a public station that can fuel a vehicle in a few minutes.
Benefits to Home Refueling
Generally, natural gas prices are lower and traditionally more stable than gasoline. Taxes on natural gas as a vehicle fuel are usually lower and may result in substantial savings over gasoline.
Ease of Paying Fuel Bills: By filling up at home you eliminate having to pay multiple fuel bills. You receive one monthly bill from PG&E that includes both your vehicle refueling and home natural gas usage. For more information, check out our home refueling rate (G1-NGV) for HRA devices.
