New hydrogen chapter, Mercedes-Benz GenH2 Truck enters customer trials

Daimler Truck is moving its long-haul roadmap from diesel to hydrogen: the Mercedes-Benz GenH2 Truck, a fuel-cell electric heavy-duty tractor, is now entering customer testing with logistics groups in Europe. The beta-phase truck targets long ranges and high payloads for future series production.

The move from pilot prototype to real freight work is beginning for Daimler Truck's hydrogen program: the Mercedes-Benz GenH2 Truck, a fuel-cell electric heavy-duty tractor for long-haul operations, is now entering customer trials with European logistics groups as the company prepares for series production in the second half of the decade. Daimler Truck positions the GenH2 as a future complement to its battery-electric portfolio, aiming at long ranges of up to around 1,000 kilometers per refueling stop in its definitive version and diesel-like performance for transport companies.

Hydrogen long-haul concept: what the GenH2 Truck is designed to do

The Mercedes-Benz GenH2 Truck is Daimler Truck's concept for a long-distance tractor unit powered by hydrogen fuel cells, built on a heavy-duty chassis comparable to diesel Actros models but with a dedicated electric powertrain and hydrogen storage system instead of a combustion engine. Daimler Truck has stated in previous technical presentations that the target configuration uses liquid hydrogen (LH2) stored in insulated tanks feeding a fuel-cell system that charges a buffer battery and drives electric motors on the rear axles, combining high energy density with the ability to maintain cruising speeds over extended distances under full load. The truck is conceived for gross combination weights typical of European long-haul freight, with engineering targets around the familiar 40-ton range, so that fleets can swap diesel tractors for hydrogen-electric units without changing trailer configurations or payload assumptions.

In the current development phase, test vehicles use an integrated fuel-cell stack and high-voltage battery to deliver power to the e-axle, while engineers refine cooling, control software and energy management under real-world conditions. Daimler Truck has emphasized that the GenH2 Truck is intended for routes where battery-electric trucks would face practical limitations because of energy storage volume and charging times, such as trans-European corridors with daily mileages significantly above 300 miles, making schedule-keeping difficult if drivers had to wait for repeated high-power charging sessions. By contrast, the hydrogen concept aims at refueling times closer to diesel, with the long-term goal of achieving refueling stops on the order of minutes at suitably equipped stations once standards and infrastructure are in place. In the early customer trials now starting, the prototype trucks are expected to run on specific corridors where project partners have access to pilot hydrogen filling stations, allowing Daimler Truck and logistics operators to gather operational data on consumption, uptime and driver feedback.

The GenH2 Truck fits into Daimler Truck's dual-track decarbonization strategy, which foresees battery-electric vehicles for regional and certain long-haul applications, and hydrogen fuel-cell trucks for particularly demanding operations with very high daily mileage and payload requirements. In parallel with the GenH2 development, Daimler Truck is also advancing hydrogen combustion and infrastructure partnerships, but the fuel-cell platform is planned as the core technology for its longest-range zero-emission trucks in Europe in the 2030 time frame. For logistics customers looking at fleet renewal cycles of seven to ten years, the start of customer trials is a key signal that hydrogen trucks are moving from pure concept studies towards practical deployment, even though full commercial availability will depend on regulatory support and a sufficient network of refueling stations.

Daimler Truck has previously presented the GenH2 Truck publicly at industry events and trade fairs, outlining its goal to reach production in the second half of this decade once technical validation and cost optimization are sufficiently advanced. The company has also launched separate projects, such as the NextGenH2 fuel-cell truck collaboration with logistics provider Dachser, to put early production-intent vehicles into service and test them in real freight operations. While detailed US launch plans for the hydrogen long-haul platform have not been published, the European trials are expected to inform future rollouts in other regions, including North America, where Daimler Truck operates under the Freightliner and Western Star brands.

Strategically, the GenH2 Truck is one of Daimler Truck's flagship zero-emission projects in Europe and a central pillar of its plan to offer only CO2-neutral new vehicles in its core markets by 2039. Alongside the battery-electric eActros and eEconic, the hydrogen truck broadens the company's portfolio and responds to pressure from major shippers and fleet operators to decarbonize supply chains over the coming decade. Daimler Truck is publicly listed in Frankfurt under ISIN DE000DTR0CK8; shares last traded on Xetra around EUR 40 in mid-June 2026, reflecting investor attention on its progress in zero-emission technologies as well as its conventional truck and bus operations.
