FedEx Freight has purchased more than 100 compressed natural gas powered tractors and has installed a CNG fueling station to serve its CNG fleet in Oklahoma City Service Center.

FedEx Freight contracted Clean Energy Fuels to design build and maintain its fueling station. The FedEx Freight facility includes a four-lane, fast-fill station as well as a time-fill station which has six zones and 18 hoses.

In time-fill applications, drivers connect their vehicles to an automated system in which the tractors are fueled over an extended period of time typically overnight.

FedEx Freight is a subsidiary of FedEx and a provider of less-than-truckload services. The CNG expansion in Oklahoma City is part of FedEx’s company initiative to reduce its environmental impact. The company has upgraded air and ground fleets, used biofuels and introduced programs like FedEx Fuel Sense and EarthSmart.

“A fact we take very seriously at FedEx is that people want to do business with companies who invest in making the world a better place,” said Michael Ducker, president and CEO of FedEx Freight. “Plus, it’s simply the right thing to do. And given that the state of Oklahoma has been so supportive of sustainable transportation solutions, we felt this was the perfect place to set a strong example within the LTL industry.”
