Hydrogen could play an increasingly important role in powering agricultural and construction machinery, but one of the biggest challenges of the technology remains its storage. Hörmann Vehicle Engineering from Saxony offers a new solution with an innovative hydrogen storage system integrated into the wheel. The essence of the concept is to store hydrogen not in separate tanks but in the wheels of the vehicle. The ring-shaped tank is placed in the previously unused space between the wheel hub and the rim, so there is no need for significant modifications to the machinery's design. The tank is protected by a cover against contaminants and mechanical damage. The system uses carbon fiber-reinforced (CFRP) tanks that store hydrogen at a pressure of 700 bar. According to the developers, the rear wheels of a tractor can hold up to 40 kilograms of hydrogen on each side, which corresponds to the energy content of approximately 200 liters of diesel. This means that the operational time of ...
