Natural Gas Vehicles

Natural gas vehicles (NGVs) fueled by compressed natural gas (CNG) or liquefied natural gas can have a positive impact on environmental air quality. Natural gas is a clean, cost-effective alternative fuel choice. Compared with conventional vehicles, NGVs produce only 5 to 10 percent of allowable emissions, which means far less greenhouse gases.*

The use of NGVs not only helps the environment, it decreases U.S. dependence on foreign energy sources and relies on the abundant supply and reliable distribution network of natural gas within the U.S.


What are natural gas vehicles (NGVs) and how do they work?
A natural gas vehicle is a car, truck, van, bus or even forklift that runs on natural gas. Natural gas is compressed or liquefied so that it can be stored in safe, secure aluminum, fiberglass, steel or carbon-fiber cylinders within the vehicle.

NGVs work like traditional vehicles, burning a gaseous blend of fuel and air in an engine. Because natural gas is clean burning, NGVs have significantly lower emissions than conventionally fueled vehicles. The U.S. Environmental Protection Agency (EPA) has called the natural gas Honda Civic GX the cleanest internal-combustion vehicle on Earth.

How safe is an NGV?
Within an NGV, the compressed natural gas cylinders are significantly stronger than gasoline tanks, and they meet or exceed U.S. Department of Transportation safety standards. Although highly unlikely, should a leak occur, natural gas will not produce flammable liquid on the ground, but rather will rise and disperse if released.


How do I get an NGV?
The Honda Civic GX is the only factory built CNG automobile currently available for consumer purchase in the U.S. It is a dedicated vehicle meaning it only runs on natural gas. The GX is available at most Honda dealerships. Fleet operators can now purchase vehicles directly from Ford, GM, and Chrysler. Currently, each company has trucks and vans that can be ordered from local dealerships with future availability expected to increase.

New vehicles may be converted to run on natural gas using an EPA-certified conversion kit. EPA guidelines have recently changed to exempt older vehicles from this certification requirement if they meet certain conditions. Refer to EPA publication, EPA-42-F-11-006 for an outline of the new requirements. Also, visit NGV America to identify vehicles with available EPA-certified kits, and to identify companies that manufacture conversion kits for a variety of vehicles.

PSNC Energy does not sell CNG conversion kits for vehicles.

What is the CNG equivalent to a gallon of gasoline?
1.26 Therms = 1 Gallon equivalent of gasoline
1.4 Therms = 1 Gallon equivalent of diesel fuel

What are the refueling options for NGVs?
CNG is put into vehicles similar to the way gasoline is used to refuel. There are two refueling options: "fast fill" and "time fill."

"Fast fill" can be done at a natural gas refueling station and takes about five to seven minutes. "Time fill" refueling takes from four to eight hours, and is intended for home and commercial refueling where the vehicle will sit unused overnight, or for an extended period of time. Residential refueling appliances and commercial refueling stations may be installed wherever natural gas is available. There are several CNG stations available for public use in North Carolina.

What about CNG stations for commercial fleets?
Commercial fueling stations designed to provide CNG for larger single vehicles or multiple vehicles in a fleet are available and will vary in design and cost, depending on the needs of the customer. Stations can be designed for either fast fill, time fill or a combination of both. The cost for a commercial station will vary depending on the number of vehicles or the need for “fast fill” stations.
