(Stuttgart / Germany) – Daimler Truck AG plans to begin large-scale industrialization of fuel cells and the planned series production of its hydrogen-powered trucks in Europe only in the "early 2030s." The reason given is that the "expansion of hydrogen refueling stations is progressing significantly slower" than expected.

Nevertheless, following the completion of initial customer-facing trials, the practical testing of the Mercedes-Benz GenH2 fuel cell trucks is now entering its second phase. Five companies are participating: the DIY chain Hornbach Baumarkt AG, the freight forwarding company Reber Logistik GmbH, the pharmaceutical manufacturer Teva Deutschland ("Ratiopharm"), the logistics company Rhenus SE&Co KG, and DHL Supply Chain (Deutsche Post). Each company will operate one truck for a year on different routes within Germany, using various logistics applications. The test results and operating scenarios will directly inform the further development of the vehicle and preparations for sales and service processes.
Liquid hydrogen for greater range
The "GenH2," with a total weight of approximately 40 tons, offers a payload of about 25 tons. The fuel cell system delivers 300 kilowatts of power, supplemented by a small auxiliary battery for peak load support and energy recovery during braking (recuperation). The liquid hydrogen used has a higher energy density than gaseous hydrogen, enabling greater range per tankful and reduced transport costs. The vehicles are refueled at designated subcooled liquid hydrogen (sLH2) filling stations in Wörth am Rhein and the Duisburg area.
As part of the initial practical trials, five trucks have already covered a combined distance of over 225.000 kilometers. Average hydrogen consumption ranged from 5,6 to 8,0 kilograms per 100 kilometers, with an average gross vehicle weight between 16 and 34 tons. In September, Daimler announced its intention to build 100 tractor units at its Wörth plant and begin field trials with additional customers starting at the end of 2026 ( as previously reported ).
