Danfoss Editron has provided the electric power equipment for 'Tellus', which will become Sweden’s largest hybrid-electric car ferry when it shortly enters passenger operations.

The ferry was designed by FKAB and commissioned by the Swedish Transport Administration (STA). It is 100m long × 18m wide and has capacity for 80 cars and 297 passengers. The vessel, built by Baltic Workboats in Estonia, will operate on the 1.8km Gullmarsleden route linking Uddevalla to Lysekil, said to be one of Sweden’s busiest maritime routes, with over 100,000 vehicles transported per month, including many heavy trucks.

Tellus will mainly operate on fully-electric mode, bringing STA closer to achieving its target of becoming fossil-free by 2045. This is Danfoss Editron's third collaboration with Baltic Workboats. The Danfoss Editron lightweight electric powerplant is connected to 12 Corvus battery racks with total capacity 949kWh. The batteries are currently charged overnight via an on-shore charging station and can be charged by diesel engines while the ferry is in operation. This temporary solution will be replaced by automatic charging stations at the harbour once the infrastructure is ready.

In addition to controlling the ferry’s propulsion, the Editron load control system automatically supervises the powerplant and ensures that fuel consumption is optimised at all times. When in hybrid-electric mode, the ferry will operate on a single genset, with the rest of the propulsion supported by battery power. The control system’s separation operation mode ensures that the ferry’s captain can easily choose the most appropriate operation mode and swiftly switch between modes if necessary.

Jani Hartikka, Project Manager, Danfoss Editron, said: “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. The versatility of our Editron system means that we can provide fully-electric and hybrid solutions for any kind of ferry. The future of the marine sector is definitely emission-free.”

Peter Peterberg, Environmental Coordinator,STA said: “We are delighted to add the Tellus ferry to our fleet, which demonstrates that emission-free solutions are as efficient as their diesel counterparts. Our plan is to continue to upgrade our vessels with hybrid-electric systems in order to operate the most sustainable fleet possible in a near future.”
