Electric ferry - Ellen sailed 50 nautical miles – 92 kilometres – on a single battery charge, during the International Energy Agency’s 7th Annual Conference on Energy Efficiency. The distance marks a new world record.

The islands of Ærø and Als in Southern Denmark are connected by Ellen, the longest ranging fully electric ferry in the world.

Electric ferry – Ellen sets world record

Ellen set a new world record on June 9, 2022, just outside the windows in Sønderborg, Denmark, where leaders from industry, government, and civil society joined the International Energy Agency (IEA) for the 7th Annual Global Conference on Energy Efficiency.

On her return from the conference, where participants explored how international ambition on energy efficiency can be translated into faster and stronger real-world progress, Ellen reached a total of 50 nautical miles – 92 kilometres – on a single battery charge.

A clear e-ferry record

Henrik Hagbarth Mikkelsen, Senior Lecturer at Marstal Naval Academy, Denmark, who helped specify the technical solutions for the ferry during its design-phase, was on-board for the trip, stated “The 92 kilometre trip on a single battery charge is the longest planned distance for an electric ferry, able to carry both passengers and vehicles to date, anywhere on the globe.

Henrik Hagbarth Mikkelsen adds, “We are talking about a clear record. On its normal, daily trips, the ferry sails 22 nautical miles, or 40 kilometres, from harbour to harbour, before recharging.

Danfoss supplies Editron drivetrains and propulsion motors

The electric ferry - Ellen does not emit carbon and operates at 24 percent lower cost

The electric ferry - Ellen does not emit carbon and operates at 24 percent lower cost, in comparison to a new diesel ferry. She started sailing in 2019. Danfoss has supplied electric Editron drivetrains and propulsion motors for the ferry.

Kimmo Rauma, the Vice President - Danfoss Editron at Danfoss, said “Ellen is an excellent example of the future for electric transport. It’s cleaner, greener, and more efficient than her fossil fuel competitors.

Electrifying maritime transport

Kimmo Rauma adds, “Electrifying maritime transport is a clear-cut way to reduce greenhouse gas emissions. And, Danfoss has the solutions to build new electric ferries and to retrofit existing ones, to electrify them with the potential to reduce carbon emissions all over the world.

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