Danfoss Editron informed that Sweden’s largest hybrid-electric ferry, Tellus, is soon to begin operations. The ferry will mainly operate on a fully-electric mode, bringing the government agency closer to achieving its target of becoming fossil-free by 2045. The ferry will service Sweden’s busiest maritime routes, along with more than 100,000 vehicles transported per month, the majority being heavy trucks.
Built and delivered by Baltic Workboats shipyard, the 100-meter-long ferry will be capable of transporting up to 297 passengers and 80 cars per journey on the 1.8km Gullmarsleden route linking Uddevalla to Lysekil.
Baltic Workboats collaborated with Danfoss Editron, who delivered the electric powerplant and propulsion system for the newbuild.

Moreover, the electric powerplant connects with the 12 battery-racks provided by Corvus batteries, which have a total capacity of 949 kWh. The batteries are currently charged at night via an on-shore charging station and can also be charged by diesel engines while the ferry is in operation. Yet, this is a temporary solution that is planned to be replaced by automatic charging stations at the harbor once the infrastructure is ready.
The Editron control system focuses on the powerplant and ensures that the fuel consumption of the vessel is all the time optimised, even in occasions when the ferry is not operating on fully-electric mode only.
In addition, the control system’s separation operation mode ensures that the ferry’s captain will be able to choose the ideal operation mode and swiftly switch between them if necessary.
Jani Hartikka, Project Manager at Danfoss Editron concluded
Similar ferries are already in operation in Finland and Norway, so we are thrilled to see Sweden joining the movement. The electrification of the marine industry is a trend which will continue to grow as more countries introduce legislation related to reducing emissions in the sector.
