Since 2013, we have operated with less emission intensive hybrid technology. In 2020, we installed a rotor sail on M/V Copenhagen and in 2022 on M/V Berlin respectively, which operate on our route between Rostock in Germany and Gedser in Denmark. With the rotor sail from Finnish Norsepower, we can further reduce CO2 emission from the hybrid ferries.
The rotor sail is based on the almost 100-year old concept of the Flettner rotor technology. It is a 30 metre tall, rotating cylinder, which by using the Magnus-effect contributes to pushing the ship forward. When the wind meets the spinning cylinder, the airflow accelerates on one side of the cylinder and decelerates on the opposite side of the cylinder. The change in the speed of airflow results in a pressure difference, which creates a lift force that pushes the ship forward perpendicularly to the wind flow direction.
A rotor sail has the optimum effect when it is windy and the wind comes from the side. The route between Gedser to the north and Rostock to the south is almost perpendicular to the prevailing wind from the west or the east. This gives us favourable conditions for using rotor sails on the crossing.
With assistance of the rotor sail we reduce the CO2 emission by four percent on average.
With assistance of the rotor sail we reduce the CO2 emission by four to five percent.

A fleet of hybrid ferries
The hybrid system on ferries is similar to that of hybrid cars, where petrol or diesel is combined with electricity.

Noise-reducing thrusters
One of the steps towards our zero emission strategy is the exchange of all thrusters – the ships’ propulsion systems – on Scandlines’ four hybrid ferries on the route between Puttgarden in Germany and Rødby in Denmark.

Sustainability in action
We reduce food waste by serving individual portions made to order, putting smaller amounts of food on the buffet at the time and by having less dishes from which to choose.

Zero direct emissions-freight ferry
Scandlines has ordered a new zero direct emissions-freight ferry for the Puttgarden-Rødby route. The ferry will be inserted in 2025 and will launch the next generation of ferries on the route.

Reduction of energy consumption
Our current focus is on reducing our ferries' energy consumption per crossing. We are investing in energy efficiency and operational adjustments that lead to energy savings.

Electrification of the ferries
Scandlines is now taking the next big step on the green journey, converting two of the four passenger ferries operating the Puttgarden-Rødby route into plug-in ferries.
