Natural gas costs less than gasoline and diesel fuel. Consequently, consumers are investigating options to retrofit or convert cars or pick-up trucks to run on natural gas.
The U.S. has about 1,000 CNG fueling locations, and more are being built. About half are open to the public. Others can be used only by opening an account or using a credit/proprietary billing card. Check fueling options before converting a vehicle to run on natural gas — or before purchasing one. You can find locations at these websites:
No. Only certain model vehicles have certified NGV conversions available. Get conversion availability information for your vehicle as well as cost and benefit details at ngvc.org.
Yes. However, only certain model vehicles have certified NGV conversions available. To check the availability of conversions for your vehicle or new vehicle NGV models go to ngvc.org.
Cost ranges from $7,000 to $18,000, which includes the retrofit system, fuel tanks related tubing/brackets and installation. Converting a new vehicle provides the best opportunity to recover conversion cost because of the longer time for fuel cost savings. Only certain model vehicles have certified NGV conversions available. Check availability at ngvc.org.
We have some NGVs in our fleet. Some of our service centers have CNG stations, and most are open to the public. The stations are owned and operated by U.S. Oil. Locations
Current CNG prices are available at cngprices.com. Prices are listed as gasoline gallon equivalent (GGE). GGE is the CNG amount that is equivalent to the energy in a gallon of regular gasoline.
Natural gas is a minor component of CNG pricing. CNG prices also include cost of:
Because CNG pricing includes multiple components, price volatility is reduced, though natural gas prices do have an impact as well.
No. The PSCW does not regulate transportation fuels.
Just drive up to the dispenser at any CNG station open to the public. Most are self-serve with no attendants. CNG refueling uses a connector for a tight, closed connection that is secured prior to fueling. This video demonstrates how to fuel an NGV:
Most CNG stations allow public fueling with credit card and/or proprietary billing card access (full public access). Many CNG stations are located at convenience store fueling stations that take cash as well as major credit cards. Some stations allow public refueling only after an account has been opened (limited public access).
Typically, contact a dealer or the manufacturer.
CNG makes up only 0.04 percent of the U.S. transportation fuel market. Because CNG stations are expensive to build, maintain and operate, growth is slow.
Public access CNG stations may cost more than $700,000 to build. Grants have been available in the past to help fund public access CNG station installations. When available, grants in Wisconsin are made through Wisconsin Clean Cities, a local nonprofit alternative fuel organization, or Wisconsin State Energy office.
If the station is located in our service area, we supply it. This map shows our natural gas service areas and major highway and transportation corridors: Map
Natural gas feeds to CNG compressors often require special handling. Contact our Customer Care Center at 800-714-7777 ext. 7700, Monday through Friday, 8 a.m. to 5 p.m., to help us meet your special natural gas supply needs, such as greater pressure and volume. We can assign a service manager to help you get the best pressure and flow for a proposed CNG station.
We have no plans to install any CNG stations at this time. We are interested in supplying natural gas to customers who want to compress natural gas for use as a transportation fuel.
Equipment called a Phill unit can refuel an NGV at a home or business. The unit, which costs $4,000 to $5,000 installed, can fill one NGV car or small truck overnight. We do not sell, furnish or install this equipment.
CNG stations take natural gas at about 10 pounds per square inch (psi), dry it, compress it in stages up to 4,500 psi, store it and then dispense it safely at 3000 to 3600 psi. Heat, pressure, vibration and age all take a toll on equipment and safety systems. Highly trained technicians maintain and repair the equipment, which can be hazardous because of the high-pressure gas.
