World’s largest electric ferry completes maiden voyage

The world’s largest all-electric ferry made its first commercial trip last week in southern Denmark. It is powered by a battery system with an unprecedented 4.3MWh capacity from Swiss energy storage company Leclanché.

E-ferry Ellen, the largest all-electric ferry in the world, connected the ports of Søby and Fynshav, on the islands of Aerø and Als, in southern Denmark on its maiden voyage last week. The e-ferry is capable of carrying around 30 vehicles and 200 passengers.

Swiss energy storage company Leclanché provided the groundbreaking battery system for the project.

“We are very proud to provide specifically designed unique lithium-ion battery system to this ferry, the precursor to a new era in the commercial marine sector,” said Leclanché CEO Anil Srivastava. “With its 4.3MWh capacity, the e-ferry represents a new milestone in commercial marine propulsion.”

The battery system uses high-energy G-NMC lithium-ion cells with several safety features, including a bi-cellular laminated design and ceramic separators. It also features fire prevention and extinguishing systems.

According to Srivastava, the e-ferry will prevent the release of 2,000 tonnes of carbon dioxide, 42 tonnes of nitrogen oxide, 2.5 tonnes of particulates and 1.4 tonnes of sulphur dioxide into the atmosphere.

“This project demonstrates that today we can replace fossil fuel thermal drives with clean energy, and thus contribute to the fight against global warming and pollution for the well-being of our communities,” he said.
