As interest in environmentally friendly and sustainable solutions in heavy vehicle transport increases, a significant development is taking place under the leadership of German automotive giant Mercedes-Benz. The brand aims to revolutionize the sector with its new NextGenH2 truck equipped with hydrogen technology. With this model, it not only provides zero emissions but also makes a difference in the logistics field with its high performance and long range features.
Mercedes-Benz, having made a rapid start to the project, plans to launch series production in 2023 with a limited run of only 100 units. The delivery of the first trucks will clearly demonstrate the potential of hydrogen fuel cell technology in the heavy-duty transport sector. These trucks could usher in a new era in long-haul transportation by offering range and refueling times comparable to diesel-powered vehicles.
The technological infrastructure of the Mercedes NextGenH2 hydrogen truck has been designed in a highly innovative way. This system features a large battery that acts as a buffer between the fuel cells, which are the energy source, and the electric motors. Inside the truck, 101 kWh capacity lithium iron phosphate (LFP) battery It is located there; this battery is used to increase performance in situations requiring high power and to recover braking energy. In fact, the NextGenH2 operates like a fully electric vehicle with a range extension function. Electrical energy is provided by electricity generation from two fuel cells under the cab, and in total 300 kW power produces.
This design eliminates the need for external charging for the truck; the energy obtained from the hydrogen tanks is sufficient for the vehicle's movement. Furthermore, this technology offers significant advantages in terms of range and refueling time for users, making a difference, especially in long-haul transportation.
Advantages of using liquid hydrogen One of the remarkable features of Mercedes' new truck technology is that instead of compressed gas... liquid hydrogen (LH2) The secret lies in its use. Liquid hydrogen is stored at temperatures as low as -253°C and provides a much higher energy density compared to its gaseous state. This allows for longer ranges with smaller tanks, providing a significant advantage in logistics. The truck has a total of two stainless steel tanks mounted on the chassis. 85 kg of liquid hydrogen It has storage capacity, and that's when it's fully filled. A distance of over 1000 kilometers. This allows for the necessary travel. In tests, the vehicle was used with a load of approximately 16 to 34 tons, averaging 100 km per kilometer. It consumes between 5.6 and 8 kg of hydrogen. This was observed, indicating that hydrogen-powered trucks could be competitive in long-distance transportation.
The rapid filling capability of the tanks is another important advantage of the technology. Developed in collaboration between Daimler Truck and Linde. sLH2 (subcooled for liquid hydrogen) filling standardsonly the truck's 85 kg tanks 10 to 15 minutes It can be fully charged between [times]. This time is close to the speed at which diesel vehicles refuel and surpasses the long charging times of electric trucks. Series production is based on the Actros platform, maintaining its reliability and durability. In addition, the latest infotainment and safety technologies are standard equipment to ensure safe and comfortable journeys for drivers. Mercedes-Benz Trucks plans to deliver the first vehicles at the end of 2026, with full series production expected to begin in the early 2030s. These developments send a strong signal about the future of hydrogen technology in the automotive sector.
