Mercedes-Benz's GenH2 Hydrogen Fuel Cell Truck Enters Testing Phase
TapTechNews August 23rd news, Daimler Trucks under Mercedes-Benz has entered the next stage of hydrogen fuel cell truck research and development. After tests 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 the real logistics and transportation environment.
At the launch ceremony, Daimler Trucks, together with AirProducts, 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, these five GenH2 trucks will be put on specific routes in Germany to serve different long-distance transportation application scenarios such as building materials, shipping containers, bottled gases, etc. During the test, the trucks are still directly responsible 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 total combined weight (GCW) of 40 tons and an effective payload of about 25 tons. TapTechNews noticed 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 the joint venture cellcentric of Daimler Trucks and Volvo Group.
The fuel cell system of the GenH2 truck can provide 300 kW (2x150 kW) of power, and the built-in battery can provide an additional 400 kW of power within a limited time.
The storage capacity of the battery is relatively low, 70 kWh, and the official explanation is that the battery is not used to meet the energy demand, but to provide additional power support for the fuel cell under specific conditions, such as peak loads or full-load climbing situations during acceleration. Moreover, the relatively light battery can also support a higher effective payload.
In the trial production version, the design of the dual motor, the total continuous output power can reach 2x230 kW, and the peak output power is 2x330 kW. Correspondingly, the truck torque is 2x1.577 Nm or 2x2.071 Nm.
GenH2 trucks are equipped with two stainless steel hydrogen storage tanks, and the single tank capacity can reach 44 kilograms. The stainless steel tank system consists of two interconnected tubes with a double-layer design and vacuum in sulation.
