E-ferry Ellen

During the 7th Annual Conference of the International Energy Agency, the electric ferry Ellen covered 50 nautical miles – 92 kilometers – on a single battery charge. This distance represents a new world record.

The islands of Ærø and Als in southern Denmark are linked by Ellen, an all-electric ferry with the world’s longest range. The ferry was able to set a new world record on June 9th as part of the IEA climate conference.

After returning from the conference, where industry, government and civil society leaders shared quick and effective energy efficiency measures, Ellen covered 50 nautical miles – 92 kilometers – on a single battery charge.

A clear record for electric ferries

Henrik Hagbarth Mikkelsen, Senior Lecturer at Marstal Naval Academy in Denmark, who helped define the technical solutions for the ferry during the design phase:

“The 92-kilometer journey on a single battery charge is the longest planned distance that an electric ferry capable of carrying both passengers and vehicles has ever traveled anywhere in the world. We’re talking about a clear record here. On their normal, daily.” trips, the ferry travels 22 nautical miles or 40 kilometers from port to port before it needs to be recharged.”

Ellen has been in operation since 2019. The electric ferry emits zero carbon and operates 24 percent cheaper than a new diesel ferry. Drive trains and propulsion motors for the ferry were supplied by Danfoss.

Kimmo Rauma, Vice President, Danfoss Editron: “Ellen is a great example of the future of electric transport. She is cleaner, greener and more efficient than her fossil-fuelled competitors. Electrification of maritime transport is a clear path to reducing greenhouse gas emissions. And Danfoss has the solutions to bring new electric ferries build and retrofit existing ferries to make them electrified, with the potential to reduce carbon emissions around the world.”

Danfoss Editron plans to submit the world record to Guinness World of Records.
