Last week, Daimler Truck revealed the triumphant completion of a test run for its prototype vehicle, the Mercedes-Benz GenH2 Truck. The hydrogen-electric semi-trailer successfully navigated a 1,047-kilometer (650-mile) distance on just one hydrogen refueling.
The truck accomplished the journey across Germany, commencing from Woerth am Rhein and culminating in Berlin, while emitting no carbon dioxide. The test was executed with the truck carrying a full load, with a gross weight of 80,000 pounds, thereby mirroring the range commonly achieved by traditional diesel-fueled trucks.
Overview of Volvo XC40
Initially showcased in 2020 as part of the Mercedes-Benz GenH2 Truck concept, the vehicle employs a dual electric motor powertrain. Each of these motors is capable of supplying a steady 308 horsepower and 1,163 pound-feet of torque, with peak capacities reaching 442 horsepower and 1,527 pound-feet.
Generally, these motors source their energy from a hydrogen fuel-cell stack. However, during high-demand scenarios, supplementary energy is provided by a battery with limited capacity, which is primarily employed for temporary needs such as overtaking or ascending steep gradients.
Cellcentric’s Dual Fuel-Cell System for Heavy-Duty Utilization
The GenH2 Truck incorporates liquid hydrogen storage tanks, a choice made due to their compact size compared to tanks needed for gaseous hydrogen. Each of the two tanks weighs 88 pounds. Daimler Trucks states that the stored hydrogen remains adequately chilled for an extended period without the need for active cooling, thanks to insulation.
Cellcentric, a collaborative venture between Daimler Trucks and Volvo Group’s commercial vehicle division, is behind the development of the fuel cell elements in the powertrain. The company has previously alluded to mass-producing fuel cells by the year 2025.
The prototype used for the test is modeled on the Mercedes-Benz Actros. However, its powertrain may eventually find applications in other vehicles under the Daimler Truck portfolio, including brands like Freightliner, Western Star, and Fuso, as well as Volvo Group-operated brands.
Daimler Trucks has not limited its focus to hydrogen-electric vehicles alone. The company is also in the process of designing battery-electric trucks intended for shorter distances, and has already introduced models such as the Fuso eCanter and the Mercedes-Benz eActros to the market.
