Key Takeaways

  • Clean Energy Fuels announced multiple new and extended RNG agreements with trucking, transit, municipal, and airport fleets.
  • The deals include fuel supply as well as operations and maintenance for fueling infrastructure.
  • Refuse fleets, transit agencies, and trucking companies remain among the largest adopters of RNG vehicles.
  • RNG can achieve negative carbon-intensity scores by capturing methane from organic waste and converting it into transportation fuel.

Renewable natural gas (RNG) continues gaining traction as fleets look for lower-carbon fuel options that can be deployed quickly without major changes to operations.

Clean Energy Fuels Corp. announced a series of new and extended agreements with trucking, transit, municipal, and airport fleets across the U.S., covering RNG supply, as well as fueling station operations and maintenance. The deals span multiple sectors, reflecting what the company says is continued growth in RNG adoption as fleets pursue emissions reductions while maintaining diesel-like vehicle performance.

“Fleets continue to seek proven solutions to meet sustainability targets and they’re finding that the RNG metrics deliver on multiple fronts — it’s clean, affordable, has diesel-like capability, is domestically produced, and there is a robust fueling infrastructure already in place,” said Chad Lindholm, senior vice president at Clean Energy.

Among the agreements announced, Clean Energy extended its partnership with Ecology Transportation Services, which operates one of Southern California’s largest fleets of RNG-powered trucks. The new deal will supply the company’s 150 natural gas vehicles with approximately 2.1 million gallons of RNG annually through stations across California, Arizona, and Nevada.

Waste and recycling fleets are also expanding their use of the fuel. Recology is upgrading its fueling station in Seattle and recently completed a new station in Snohomish, Washington, with Clean Energy providing operations and maintenance support for both locations. Clean Energy also continues to support WM, maintaining more than 85 RNG fueling stations across the U.S. and Canada that serve thousands of refuse trucks.

Transit agencies and municipal fleets are included in the latest round of agreements as well. The Washington Metropolitan Area Transit Authority extended its contract with Clean Energy to support its natural gas bus fleet, covering approximately five million gallons of fuel for more than 400 buses. In Phoenix, the company signed an agreement with ABM Facility Services to maintain three transit bus fueling stations that collectively supply RNG to 335 buses and dispense about 4.7 million gallons annually.

Additional contracts include supplying renewable natural gas to Arlington Transit buses in Virginia, continuing maintenance support for the City of Scottsdale’s refuse fleet, and operating the natural gas fueling station serving shuttle buses and fleet vehicles at Nashville International Airport.
