First test runs for hydrogen powered Rhenus barges

The first of the hydrogen-powered Rhenus barges is currently in the decisive phase of the shipyard test runs. Each of these three ships is undergoing intensive testing to ensure the highest standards of sustainability and technical innovation. The aim is to optimally prepare the ships for the final test run and the subsequent approval for operation.

Rhenus is taking another important step towards low-emission shipping with the development of its innovative, hydrogen-powered inland waterway vessels. The current test runs mark an important step in the construction process, during which the ships are put through their paces. Particular attention is being paid to fine-tuning the sophisticated electronic systems and checking all technical components.

One focus of the tests is on the powerful combination of fuel cell system and modern battery system. The 840 kWh battery acts as a peak load buffer and at the same time ensures that the ship remains operational even in emergencies. Two fuel cells convert hydrogen into electrical energy, and additional cells can be added if required to further increase efficiency.

In addition to the hydrogen technology, marinized truck diesel engines with an output of 350 kW each are used to ensure operability on long-distance journeys if required. In addition, the all-electric bow thruster is being tested, which ensures precise maneuvers and is powered by a powerful electric motor. Thanks to the tailor-made reversing and reduction gears of the two synchronous electric motors with an output of 960 kW, noise levels are kept to a minimum.

The test runs also include a comprehensive check of the fuel cell system and the battery under various load conditions to ensure that all systems function reliably. At the same time, cooling of the fuel cell system is ensured by two circuits for high and low temperatures.

Rhenus is setting new standards in inland shipping with these innovative technologies and is paving the way for the ships to be approved for transport, which is expected to take place in the coming months.

The UNECE (United Nations Economic Commission for Europe) has already granted special approval for the use of hydrogen as a form of propulsion. This has not yet been approved for the transportation of dangerous goods. This makes the Rhenus ship the first inland waterway vessel of its kind to be allowed to travel on the Rhine powered by hydrogen.
