NATURAL GAS VEHICLES



Natural Gas Vehicles (NGVs) offer a variety of benefits for businesses:

THEY'RE ECONOMICAL. Natural gas can reduce fuel costs significantly versus diesel or gasoline, extending engine life and reducing the frequency of oil changes.

THEY'RE SAFE. Since natural gas is lighter than air, a leak will not pool on the ground like gasoline. Compressed Natural Gas (CNG) cylinders are also much stronger than gasoline tanks.

THEY'RE ENVIRONMENTALLY RESPONSIBLE. Natural gas reduces emissions as opposed to gasoline because it produces 75% less carbon monoxide (CO), 50% less nitrogen oxides (NOx) and 25% less carbon dioxide (CO2) once consumed. Natural gas also produces 50% less engine noise than a diesel engine.

THEY PROVIDE ENERGY SECURITY. Due to its abundant supply, natural gas will last for more than 100 years. Fortunately, natural gas is also a domestic source of energy, more than 90% is produced in North America.

Which Vehicle is Right for Your Company?

LIGHT DUTY VEHICLES weigh less than 10,000 pounds and are considered Class 1 or 2.
  • Examples: passenger cars, taxi cars and service vans
  • Current incremental cost is typically $7,000 to $14,000 more than comparable gasoline vehicles
MEDIUM DUTY VEHICLES weigh 10,000 - 33,000 pounds and are considered Class 3 - 7.
  • Examples: short haul delivery trucks, transit buses and shuttle buses
  • Current incremental cost is typically $15,000 to $20,000 more than comparable gasoline vehicles
HEAVY DUTY VEHICLES weigh more than 33,000 pounds and are considered Class 8.
  • Examples: transit buses, shuttle buses, school buses, long haul tractor/trailer trucks and garbage trucks
  • Current incremental cost is typically $25,000 or more than comparable gasoline vehicles

Use Existing Refueling Stations - or build your own

The two types of NGV refueling stations are Time-fill and Fast-fill (depending upon the type of fleet and its use). Each station includes a utility gas meter, natural gas piping system, compressor and dispenser.

TIME-FILL STATION
Compressed natural gas (CNG) is dispensed slowly from a compressor to the vehicle's onboard storage tank. This eliminates the need for a high-pressure storage system. This type of fueling station is best for fleets that return to a central location and sit idle overnight or for extended periods. Typical fueling time is usually 6-8 hours. This is a lower cost station investment compared with a Fast-fill Station. Typical cost range is approximately $15,000 - $500,000.

FAST-FILL STATION
These stations are similar to a liquid fueling station, with the same fill rates and times. The vehicle receives natural gas directly from a storage system. A compressor replenishes the storage system when the fuel supply pressure drops. This type of station is a must for public access refueling and is also ideal for larger fleets where fueling turnaround time is short. Typical fueling time is usually 3-7 minutes. This is a more costly investment than Time-fill Stations. Typical cost range is approximately $500,000 - $1,500,000.

The number of public CNG fueling stations is growing every year and provide an ever-expanding source of fueling options. But should you decide to install your own fueling equipment, National Fuel offers several different rate options available to serve the natural gas supply needs for your natural gas vehicle fueling requirements. These include a Natural Gas Vehicle Rate, standard retail sales service or transportation service. For more detail, see our Rates page.

HOW NATURAL GAS VEHICLES WORK:

  1. Compressed Natural Gas (CNG) enters the vehicle through the natural gas fuel receptacle.
  2. The CNG flows into high-pressure storage cylinders.
  3. When natural gas is required by the engine, CNG leaves the cylinders and passes through the cylinder valve.
  4. The gas goes through the high-pressure fuel line and enters the engine compartment.
  5. Gas enters the regulator, which reduces pressure from up to 3,600 psi to the pressure required to open the fuel injectors.
  6. The solenoid valve allows natural gas to pass from the regulator into the fuel injectors. (The solenoid valve will also shut off the natural gas when the engine is not running.)
  7. Natural gas mixes with air then flows down through the fuel injection system and enters the engine's combustion chambers.
For more than 100 years, National Fuel's goal has been to provide customers with safe, reliable natural gas service. Moving forward, National Fuel is committed to providing you with flexible options and convenient services to help meet your needs - including supplying fuel for NGVs. These vehicles are designed to help commercial customers optimize their monetary savings, benefit the environment and provide energy security. If you want the most cost-effective and clean way to fuel your fleet, consider NGVs.
