In 2023, two manufacturers independently demonstrated real-world operation of liquid hydrogen powered Class 8 fuel cell tractor-trailers (Daimler Truck and Hyzon Motors). The Daimler demonstration truck had a GVWR of 80,000 lbs. and 80 kg cryogenic liquid hydrogen onboard storage and traveled 600 miles, under real-life conditions without requiring refueling. ​
Hyzon, in partnership with Chart Industries, demonstrated over 540 miles of cargo delivery to eight Texas locations. ​
​Daimler Truck has announced a preference for liquid hydrogen on-board storage due to the higher energy density, smaller storage volume, and longer vehicle range it affords.​
