Natural Gas Fleets

Compressed Natural Gas (CNG) and Liquid Natural Gas (LNG) are fueling transportation across the country.

As the nation benefits from an abundant domestic supply of natural gas, more companies are turning to CNG or LNG to fuel their transportation needs. It’s being used for long-haul trucks, marine vessels, trains, taxis, busses and more. NW Natural is responding to Oregon businesses who want to fuel their fleets with CNG.


1. Affordable. Businesses can save money. Natural gas is less than half the price of gasoline and diesel at the pump on an energy equivalent basis, according to the Clean Cities Alternative Fuel Price Report.

2. Green.Natural gas is one of the cleanest burning alternative transportation fuels commercially available today. It can reduce greenhouse gas emissions by nearly 30 percent and other smog-producing pollutants by up to 90 percent compared to diesel or gasoline, helping businesses meet compliance regulations.

By the numbers

Companies that rely on return-to-base vehicles, like transit agencies and solid waste haulers, have been using natural gas for years. Today, up to 50 different U.S. manufacturers produce 100 models of light, medium and heavy-duty Natural Gas Vehicles (NGVs) and engines. In the U.S., businesses and consumers operate more than 135,000 NGVs. These include:

  • More than 11,000 transit buses
  • Nearly 4,000 refuse trucks
  • More than 3,000 school buses
  • 15,000-17,000 medium-duty vehicles
  • More than 30,000 light-duty vehicles in government and private fleets
  • There are about 400 NGVs in Oregon; mostly commercial fleets of passenger and light-duty trucks, such as the airport shuttle buses.
  • NW Natural has 100 in our own company fleet

Filling up

Vehicles that return to base every day can refuel at home company, which is way fleet vehicles are most likely to operate on natural gas. NW Natural recently received approval from Oregon regulators to install, own and maintain equipment to compress natural gas for use as a vehicle fuel. Soon, we will be working with local businesses upon request to help them access natural gas to fuel their fleets.

For long-haul vehicles, the challenge is greater. For example, there are just 10 publicly available CNG refueling stations along our region’s I-5 corridor, plus two in the Boise area and seven in the Vancouver, Canada region. Some private ventures are developing a series of fueling stations, making it possible for long-haul trucks to refuel across the country.

Policy makers at both the state and federal level are exploring incentives to encourage use of CNG and LNG to reduce greenhouse gas emissions and improve air quality.
