In 2013, Scandlines was the first ferry operator in the world to introduce large-scale use of an on-board hybrid propulsion system, which stores excess energy in batteries, enabling a reduction in CO2 emissions of up to 15%. Scandlines now owns and operates the world’s largest hybrid fleet. All six of Scandlines’ passenger ferries have hybrid propulsion technology. This allows Scandlines to reduce CO2 emissions by c15,000 tons per year.
All of Scandlines’ ferries are fitted with modern closed-loop scrubber systems. A closed-loop scrubber cleans the engine exhaust streams of pollutants such as sulphur and particulate matter and reduces emissions by at least 90%.
In 2020, Scandlines began a programme to install new fuel efficient thrusters on all four passenger ferries serving the Puttgarden-Rødby route. The new thrusters will produce less underwater noise, improving conditions for marine life, and further reduce CO2 emissions. To date, two ferries have had their thrusters replaced; the remaining two will be upgraded in 2021.
In 2020, a 30-metre high rotor sail was installed on one of Scandlines’ ferries serving the Rostock-Gedser route to provide supplementary propulsion and reduce GHG emissions by a further 4-5%.
Scandlines’ investments in a greener fleet have brought several benefits, including
