The terminal tractor disembarked at the VALTE terminal of the Grimaldi Group where it will be tested in real operations. The 4×4 RORO Tractor is the first hydrogen powered unit in the world and was developed by ATENA, a research and technology hub composed of Universities, Research Institutes, and Private Company mainly based in the Campania Region of Italy.
The refuelling and operation tests will start next week under the supervision of the technical team of ATENA, VALTE, Grimaldi Group, Centro Nacional del Hidrógeno, Carburos Metálicos and Fundación Valenciaport as coordinator of this initiative.
This Terminal Tractor has a fuel cell/battery hybrid powertrain which allows the vehicle to perform all the intensive tasks that are required during roll-on/roll-off operations. Its hydrogen storage system, made of four Type 3 cylinders (350 bar), has an overall capacity of around 12 kg, which guarantees a continuous operation of at least 6 hours before refuelling, corresponding to the average duration of a working shift. The electric motor is a light and efficient device, particularly suitable for power demanding applications.
It is fed by a high-performance LiFePO4 battery, with 25 kWh energy capacity, and a 70 kW Ballard fuel cell module. In particular, the electric motor can receive power for traction from the fuel cell and battery simultaneously or charge the battery during braking or decelerations. At the same time, the fuel cell can provide power both to the electric motor and the battery, if needed. The hybrid powertrain shows high operational efficiency, since it takes advantage of a significant share of kinetic energy recovery, up to 25%.
Hydrogen is a clean energy carrier with the benefits of easy storage and when used produces no emissions other than heat and water. The hydrogen fuel cell converts H2 to electricity resulting in a zero-emission equipment that, if combined with the use of green hydrogen, is also carbon neutral. The technology shows some advantages compared to other available zero emission technologies like pure electric versions. This hydrogen version also shows a good operating range, short fuelling time and low maintenance costs.
