Daimler Truck's heavy-duty hydrogen fuel cell electric truck, the Mercedes-Benz GenH2, underwent rigorous testing on the Simplon Pass in the Swiss Alps. The two trucks completed a 14-day trial, covering 1,600 kilometers on challenging mountain roads with inclines and declines. The successful tests highlighted the truck's reliability and potential, especially in wintry conditions and at high altitudes. Mercedes-Benz Trucks aims to start small-scale production of the GenH2 by the end of 2026, with 100 trucks planned for testing before full production. Liquid hydrogen technology, with a refueling station opened in 2024, offers advantages in storage density and refueling speed compared to gaseous hydrogen. This technology choice aligns with Daimler Truck's vision for a common refueling standard for hydrogen-powered trucks. The GenH2 trucks are powered by fuel cell systems from Cellcentric, a joint venture with Volvo Group, emphasizing collaboration in advancing sustainable transportation solutions.
