Leinfelden-Echterdingen. Daimler Truck remains loyal to the fuel cell truck: With the Mercedes-Benz NextGenH2, the technology will enter a new phase from the end of 2026. Initially, however, in small series: a total of 100 tractor units are to be built and tested in everyday use by various customers.
Like its predecessor, the NextGenH2 truck continues to rely on liquid hydrogen: with one full tank, a range of well over 1,000 kilometers should be possible at full capacity. The two tanks have been enlarged and are intended to hold up to 85 kilograms of hydrogen together; the manufacturer specifies the refueling time as 10 to 15 minutes.
A fuel cell from the Canadian company Cellcentric converts the gas into electrical energy. A 101 kWh LFP battery developed by Daimler Truck serves as energy storage and buffer; the drive power is specified as up to 370 kW/503 hp.
Also new to the second generation are numerous series components from the battery-electric Mercedes eActros 600, including the aerodynamic cabin and the integrated e-axle as well as current assistance and safety systems. Thanks to a new boil-off management system and additional sensors that are designed to react in the event of hydrogen escaping, it is possible to spend the night in the cabin with the standard beds.
Mercedes-Benz Trucks sees hydrogen-based drives alongside battery-electric solutions as an important component in the electrification of road freight transport. The company does not expect regular series production until after 2030.
Experts see opportunities for H2 trucks especially where very long ranges, quick refueling and flexible long-distance transport profiles are required. However, there has so far been a lack of supply of green hydrogen at competitive costs. At the same time, the alternative technology of battery trucks is improving noticeably: ranges are increasing, charging times are decreasing.
