Daimler Truck has advanced sustainable transportation by successfully testing its next-generation fuel cell trucks in the Swiss Alps. The Mercedes-Benz GenH2 Trucks, powered by liquid hydrogen, underwent rigorous evaluations at the Simplon Pass, facing extreme winter conditions and rugged terrain. These tests showcased the trucks’ reliability and potential, offering valuable insights for refining this innovative technology. Conducted over 14 days, the trials highlight Daimler Truck’s commitment to developing zero-emission solutions for heavy-duty transport.
Key Highlights:
- Extreme Conditions: The Simplon Pass, with elevations over 2,000 meters and steep gradients, challenged the trucks in cold and snowy weather.
- Advanced Technology: The focus was on integrating the fuel cell system, high-voltage battery, e-axle, and thermal management for optimal performance.
- Impressive Performance: The trucks covered 6,500 kilometers, climbed 83,000 meters, and tackled gradients up to 12%, all while remaining CO2e-free.
- Government Backing: Daimler Truck received €226 million from the German government to support development and deployment of 100 fuel cell trucks.
- Future Outlook: Customer deployment is planned by the end of 2026, positioning Daimler as a leader in eco-friendly long-haul trucking.
The Simplon Pass tests pushed the Mercedes-Benz GenH2 Trucks to their limits. With a climb from 600 meters to over 2,000 meters, the route featured steep inclines and harsh winter conditions. Two trucks, each with a gross vehicle weight of 40 tons, navigated 1,600 kilometers of demanding up- and downhill sections. A mobile hydrogen refueling station from Air Products supported the operation, ensuring seamless testing.
Daimler’s team emphasized the Predictive Powertrain Controls system, which optimizes energy use between the battery and fuel cell, enhancing efficiency on ascents and recuperation on descents. The €226 million funding from the German Federal Ministry for Digital Affairs and Transport, along with Baden-Württemberg and Rhineland-Palatinate, will fuel small-scale production and customer trials. Assembly will occur at the Wörth plant, with trucks hitting the road by late 2026, advancing the hydrogen value chain under the EU’s IPCEI Hydrogen program.
