The 15 hydrogen fuel cell powered GSE cargo tractors are part of a fleet of more than 1,500 gas, diesel, and electric cargo tractors at the FedEx World Hub in Memphis, Tennessee that move an average 20 million pounds (approximately 2 million shipments) every day. The units are fueled by hydrogen, dispensed directly into the fuel cell systems by the truck driver from a 15,000 gallon liquid hydrogen refuelling infrastructure located on the airport ramp.

The cargo tractors are capable of pulling 40,000 lbs. of cargo on airport dollies in even the harshest weather conditions. Plug Power installed the GenFuel hydrogen refuelling station and retrofitted the GSE’s for GenDrive hydrogen fuel cell-power.

The project received a $2.5 million grant from the U.S. Department of Energy.
