Five Mercedes Benz GenH2 Trucks will take to the public roads in Germany this year to transport goods from companies such as Amazon, Air Products, Ineos, Holcim and Wiedmann & Winz.
Mercedes-Benz Trucks prefers liquid hydrogen. The two stainless-steel liquid-hydrogen tanks intended for the series version of the GenH2 Truck will have a particularly high storage capacity of 80 kilograms (40 kg each) for covering long distances, the Daimler truck stated on its site. The stainless-steel tank system consists of two tubes, one within the other, that are connected to each other and vacuum-insulated.
In the series version of the GenH2 Truck, the fuel-cell system is to supply 2 x150 kilowatts and the battery is to provide an additional 400 kW temporarily. At 70 kWh, the storage capacity of the battery is relatively low, as it is not intended to meet energy needs, but mainly to be switched on to provide situational power support for the fuel cell, for example during peak loads while accelerating or while driving uphill fully loaded. At the same time, the relatively light battery allows a higher payload. It is to be recharged in series-production vehicles with braking energy and excess fuel-cell energy. A core element of the sophisticated operating strategy of the fuel-cell and battery system is a cooling and heating system that keeps all components at the ideal operating temperature, thus ensuring maximum durability. In a pre-series version, the two electric motors are designed for a total of 2 x 230 kW continuous power and 2 x 330 kW maximum power. Torque is 2 x 1577 Nm and 2 x 2071 Nm respectively.
