IT Home reported on August 23 that Daimler Trucks, a subsidiary of Mercedes-Benz, has entered the next stage of hydrogen fuel cell truck research and development. After testing on test tracks and public roads, the official announced today that the Mercedes-Benz GenH2 hydrogen fuel cell truck was delivered to the first batch of customer fleets for testing and was inspected in a real logistics and transportation environment.

At the launch ceremony, Daimler Trucks, Air Products, Amazon, Holcim, INEOS and Wiedmann & Winz jointly launched the first batch of customer road tests of five Mercedes-Benz GenH2 hydrogen fuel cell prototype trucks.

During the nearly one-year test period, the five GenH2 trucks will be deployed on specific routes in Germany to serve different long-distance transportation application scenarios such as building materials, shipping containers, and bottled gas. During the test period, the trucks will still be directly responsible for and managed by Daimler Trucks and refueled at dedicated liquid hydrogen refueling stations in specific areas.

The Mercedes-Benz GenH2 truck used for customer testing this time has a gross combination weight (GCW) of 40 tons and a payload of about 25 tons. IT Home noted that the vehicle is equipped with two special liquid hydrogen tanks and a fuel cell system, which is also the core part of the GenH2 truck. Among them, the fuel cell system is developed and built by cellcentric, a joint venture between Daimler Trucks and Volvo Group.

The GenH2 truck's fuel cell system delivers 300 kW (2 x 150 kW) of power, with internal batteries providing an additional 400 kW for a limited time.

The battery storage capacity is relatively low, at 70kWh, and the official explanation is that the battery is not used to meet energy needs, but to provide additional power support to the fuel cell under certain conditions, such as peak loads during acceleration or full-load climbing. Moreover, the relatively light battery can also support higher payloads.

In the pre-production version, the dual-motor design has a total continuous output of 2 x 230 kW and a peak output of 2 x 330 kW. Correspondingly, the truck has a torque of 2 x 1.577 Nm or 2 x 2.071 Nm.

The GenH2 truck is equipped with two stainless steel hydrogen storage tanks, each with a capacity of up to 44 kg. The stainless steel tank system consists of two interconnected tubes, a double-wall design and vacuum insulation.
