FedEx has added 15 hydrogen fuel cell-powered Charlatte ground support equipment (GSE) cargo tractors and a hydrogen fueling station funded by a $2.5 million grant from the U.S. Department of Energy (DOE), the courier delivery company announced.

The fuel cell GSE cargo tractors are now part of a fleet of more than 1,500 gas, diesel, and electric cargo tractors at the FedEx World Hub in Memphis, Tenn., that move an average of approximately 2 million shipments every day, according to FedEx. The company will fuel the units using 15,000-gallon liquid hydrogen fueling infrastructure from Plug Power Inc. that's located on the airport ramp at FedEx's hub.

FedEx also recently worked with Plug Power and the DOE to install and test GenDrive brand hydrogen fuel cells in 35 forklifts at a FedEx Freight facility in Springfield, Mo.

FedEx Express has improved its overall vehicle fuel efficiency by 29.5 percent since 2005, according to the annual FedEx Global Citizenship Report released on April 2.
