A public road-approved prototype of the Mercedes-Benz GenH2 Truck completed Daimler Truck’s Hydrogen Record Run, covering 1,047 km (approx. 650 miles) of distance driven with one fill of liquid hydrogen, the company announced.
Powered by a cellcentric fuel-cell system and equipped with a liquid hydrogen fuel tank system, Daimler noted the run started Sept. 25 at Mercedes-Benz Truck’s Customer Center in Woerth am Rhein and finished on Sept. 26 in Berlin. According to the press release, the truck completed the run fully loaded and a gross combined vehicle weight of 40 tons under real-life conditions, without emitting any CO2 during the complete run. The record drive with sealed tanks and controlled mileage was independently confirmed by an inspection document from TÜV Rheinland.
Ahead of the run, the Mercedes-Benz GenH2 Truck was fueled with liquid hydrogen at Daimler Truck’s filling station at the company’s development and testing centre in Woerth, according to the press release. During the refuelling process, cryogenic liquid hydrogen at minus 253 degrees Celsius was filled into two 40 kg tanks mounted on either side of the truck chassis, Daimler notes. Additionally, the company states that thanks to the particularly good insulation of the vehicle tanks, the hydrogen can be kept at temperature for a sufficiently long time without active cooling.
