Scaling Cleaner Freight Movement

Alternative Fuels

There are many fuel choices beyond traditional diesel and sustainability efforts are encouraging investigation of numerous other fuels. Infrastructure for natural gas has been improving and more alternative fuels vehicles are accumulating high miles.

Several companies are currently exploring Class 8 electric trucks and hydrogen fuel cells. Even a biodiesel dynamic blending technology is emerging.

Natural gas remains one of the foundational fuels of our alternative fleet, thanks to its ability to meet our diverse needs — especially the demands of the heavy-duty, over-the-road trucks that connect our regional hubs. These big rigs travel an average of 400 to 600 miles per day and require strong pulling power. CNG and LNG have proven to be the best alternatives to diesel for these trucks, meeting their required range and performance criteria while burning cleaner than diesel. Today, there are no other scalable, economical alternatives to replace a class 8 diesel tractor except for natural gas.

Introduction & Rationale

NACFE is fuel agnostic, and we are here to help fleets use less of whatever fuel they select.  Aerodynamics, lightweighting, tire rolling resistance, tire pressure, idle reduction and other technologies are a benefit regardless of what is in the tank.

Available Systems

  • CNG (Compressed Natural Gas)
  • Biodiesel
  • LP (Liquid Propane)
  • Renewable Natural Gas (RNG)
  • LNG (Liquefied Natural Gas)
  • Electric
  • Hybrids
  • Hydrogen
  • Renewable Diesel (RD)
  • Methane
  • DME (Di-Methyl Ether)
  • Others

Fuel Economy & Other Benefits

Consequences & Challenges

Common Fleet Strategies

Many of NACFE’s key fleets, such as Frito-Lay and UPS are working heavily on alternative fuels utilization.

What People Are Saying

NACFE works closely with many organizations in the green space for commercial vehicles.  Find us at ACT Expo, Green Truck Summit, Midwest Green Fleets, DOE Clean Cities events and more.

GNA has published a report looking at leading alternative fuels options for medium-duty and heavy-duty commercial trucking entitled “The State of Sustainable Fleets 2020”.

BSR’s (Business for Social Responsibility) Future of Fuels initiative is helping fleets determine the best fuel choice for their business. See their approach and tools here at
