The world's largest all-electric ferry, named E- ferry Ellen, has made its first commercial trip connecting the ports of Søby and Fynshav, on the islands of Aerø and Als, in southern Denmark. This revolutionary ship, capable of carrying approximately 30 vehicles and 200 passengers, is powered by a battery system with an unprecedented capacity of 4.3MWh provided by Leclanché SA. For more information see the IDTechEx report on Electric and Hybrid Boats and Ships 2019-2029.
Participating in this event celebrating the first scheduled ferry service between the two Danish islands were the respective mayors of the two municipalities, Ole Wej Petersen of Aerø and Erik Lauritzen of Søndeborg. E-ferry Ellen is expected to be fully operational within a few weeks. E-ferry is part of the Danish Natura project, which aims to provide environmentally friendly transport for local residents. This project was initiated in 2015 and was funded by the European Union through the Horizon 2020 and Innovation Program.
The battery system supplied by Leclanché uses high-energy G-NMC lithium-ion cells with unique safety features, including a bi-cellular laminated design and ceramic separators. Leclanché specifically designs and engineers a Class Type Approved and Certified Marine Rack Systems (MRS) including Fire prevention and extinguishing systems. The project has received the DNV-GL Type Approval Certificate and the DNV-GL Product Certificate. The Swiss company develops and manufactures its own graphite/NMC (nickel-manganese cobalt lithium oxide) and LTO (titanate lithium oxide) cells. The parallel and redundant battery and powertrain systems make the E-ferry a safe and reliable vessel.
The E-ferry has been designed with unique integrated battery and transmission systems that offer unparalleled operating efficiency. In its fast-growing eTransport Solutions business, Leclanché is the supplier of choice of several leading maritime transport companies, accelerating the shift towards greater hybridization and electrification of the merchant fleet in compliance with new regulations on port approaches and anchorage.
