The electricity-powered option is available on the Naantali–Kapellskär route, serviced by Finnlines’ hybrid roll-on/roll-off passenger (RoPax) vessels, Finnsirius and Finncanopus. These ships feature 5 MWh batteries charged with onshore power while docked, enabling fossil-fuel-free operation at sea for select freight units. Antonio Raimo, Line Manager at Finnlines, stated: “Our utmost goal is to reduce emissions and we are already seeing concrete results. With the introduction of our new vessels, Finnsirius and Finncanopus, we have entered the hybrid era and can now offer our customers even more efficient and sustainable sea transport services. Although the cargo capacity of the vessels operating on the Naantali–Kapellskär route has increased significantly, yet absolute carbon dioxide emissions per nautical mile have decreased by 22%.”
The biofuel option, using renewable sources, is offered on key Baltic Sea routes critical for regional supply chains: Naantali–Kapellskär, Malmö–Travemünde, Malmö–Świnoujście, and Hanko–Gdynia. By opting for biofuels, Finnlines replaces fossil fuels, reducing well-to-wake greenhouse gas emissions by up to 90% compared to traditional fuels. Merja Kallio-Mannila, Commercial Director at Finnlines, noted: “Both solutions ensure low emissions – for example using biofuel can reduce carbon dioxide emissions by up to 700 kg per a trailer on the Hanko–Gdynia route.”
Passengers can also choose the biofuel option on routes including Naantali–Långnäs–Kapellskär, Helsinki–Travemünde, Malmö–Travemünde, and Malmö–Świnoujście, where renewable biofuels replace fossil fuels, lowering per-passenger emissions. Finnlines has invested significantly in fleet renewal and energy efficiency, including an order for three methanol-powered RoPax vessels set to operate between Helsinki and Travemünde in 2028–2029. Thomas Doepel, President and CEO at Finnlines, emphasized: “In April we announced of a new investment programme, which consists of three methanol-powered ro-pax vessels to enter the route between Finland and Germany. These new and previous investments will enable us to offer our customers fossil-free freight transportation. This has raised great interest and we are confident that the demand will grow in the future.”
The Green Lane service supports sustainable transport across the Baltic Sea, enhancing environmental responsibility while maintaining efficient freight and passenger services.
