Battery-Powered Car Ferry

The world’s first large, all-electric car ferry is a 100% battery driven aluminium catamaran. The 80-meter-long vessel is able to carry 120 cars and 360 passengers across the Sognefjord, in Norway. The ferry is designed with energy effižciency as the highest priority, affecting operation, hull shape, materials, and on-board systems.

The electricity in this area is generated exclusively by hydroelectric plants, making the energy the ferry uses cheaper than diesel. It also means the ship doesn’t emit even one gram of carbon dioxide, directly or indirectly.

The ferry makes its 20 minute journey 34 times a day, with a 10 minute break at port for charging the on-board, 1-MWh lithium-polymer battery pack. Furthermore, the electricity used to charge the vessel in-port comes from renewable hydropower.

Why you should care

The electric car ferry now being produced by Fjellstrand and Siemens does not discharge any greenhouse gases while operating. Compared to a standard diesel ferry serving the same route, the electric ferry has saved about 60% on fuel annually and prevents 570 metric tons of CO2 from entering the atmosphere, according to ferry operator Norled. Besides environmental benefits, the ferry will feature lower operational and maintenance costs, and a more peaceful journey.
