Daimler Truck's development team achieved a significant milestone by successfully completing extreme winter testing of the next-generation Mercedes-Benz GenH2 fuel cell trucks in the challenging Alpine terrain. The two advanced prototypes tackled snow, ice, and steep gradients, covering 6,500 km with an elevation gain of 83,000 m over 14 days. Dr Rainer Müller-Finkeldei highlighted the importance of pushing the technology's limits, emphasizing the integration of various components like the fuel cell system and high-voltage battery. Key focus areas included testing the Predictive Powertrain Control system for efficient fuel cell and battery utilization on uphill and downhill sections. The trial, supported by a mobile hydrogen refuelling station, is part of a larger program funded by €226 million, aiming to develop and deploy 100 GenH2 trucks by late 2026. This initiative not only focuses on vehicle development but also covers feasibility studies along the hydrogen value chain and infrastructure investments. The successful winter tests demonstrate the durability and performance of fuel cell trucks in extreme conditions, highlighting hydrogen's role in sustainable freight mobility and decarbonization efforts.
