feature coupling system proves beneficial for eco-friendly electric vessel
Since August 2017, Germany’s first electrically driven excursion vessel has been travelling across Baldeney Lake in Essen. This low noise performance and eco-friendly vessel features a methanol tank, fuel cell and motor, with the coupling system for the drive having been developed and delivered by Reich-Kupplungen. The coupling unit consists of
the Multi Mont Sella 100 claw coupling, the Arcusaflex 5.1 flange coupling and two electromagnetic clutches. The engineers, however,
faced the challenge of delivering a switchable propulsion drive system which allows the automated use of the three drive types: purely electric drive, pure diesel drive, or combined diesel-electric drive. To reduce the occurring vibrations of the engine, the motor and the drive components, flexible and highly- flexible couplings are combined with the electromagnetic clutches and integrated into a compact housing to form a compact unit.
CLEAN FUEL, CLEAN SHIPPING The future of clean shipping lies in clean fuels, and this is the first vessel in Germany with a motor powered by an eco-friendly methanol fuel cell.
The energy required for operation is generated from renewable energy sources. Ethanol is created by a run-of-river power station located directly at the dam of Baldeney Lake; and carbon dioxide for the electro-biocatalytic methanol production is filtered from the ambient air by means of a container. Using hydroelectric power, the enzymes are stimulated to convert water and carbon dioxide into methanol. Additional methanol, also
produced in an eco-friendly manner, is bought from Iceland. 330 litres of methanol, which supply enough energy for 16 hours, are
then used to generate electricity in the 35-
kilowatt fuel cell of the vessel to power the vessel’s electrical system and the battery-powered motor. The two batteries, with a capacity of 50 kilowatt
hours each, last for four hours and then need to be recharged by the fuel cell – or by using a charging cable onshore. In case of an emergency, an additional diesel engine is used.
How tHE mEtHANoL HybrId drIvE workS: 1. The hydroelectric power station at Baldeney Lake filters carbon dioxide from the air.
2. Using electricity and water, the carbon dioxide is converted to methanol, a bioalcohol. Methanol can be stored, transported and filled in just like petrol.
3. On board the vessel, the fuel cell uses the methanol to generate electricity and to supply it to the battery-powered motor.
4. During voyage, the vessel’s motor only emits as much carbon dioxide as was originally filtered from the ambient air for the methanol production.
5. In an emergency, the diesel engine can be activated via the intelligently designed coupling system to charge the battery via the generator as well as to power the propeller directly.
