World's First All-Electric Car Ferry

Vessel and Shore Charging Stations

Norled AS, MF Ampere Ferry powered by Corvus Energy ESSs on both vessel and shore charging stations. Skipsrevyen’s “2014 Ship of the Year”

Norwegian ferry company Norled AS, shipyard Fjellstrand and Siemens AS have jointly developed the world’s first fully electric battery powered passenger and car ferry. MF Ampere operates between Lavik and Oppedal, Norway. This revolutionary vessel is powered by a lightweight Corvus Energy Storage System (ESS), weighing only 20 metric tons, which provides all power to the vessel while at sea. The project is also the first of its kind to incorporate high power shore charging using Corvus Energy’s liquid-cooled ESS technology.

The first of many such vessels planned for Norway, the MF Ampere demonstrates that the robust Corvus ESS technology may be used to replace all traditional engines on ferries operating on short crossings. The project also validates the use of ESS shore charging stations where port electrical infrastructure is weak.

Shore Charging Stations - An Innovative and Custom Solution

Sognefjord, Western Norway

MF Ampere operates in Western Norway on the Sognefjord. The 80-meter vessel can carry 120 cars and 360 passengers. From 2015 onward, it will serve the route between Lavik and Oppedal, Norway, across the Sognefjord.

Shore Charging Stations - An Innovative and Custom Solution

Due to the innovative design offered by Siemens AS and Corvus Energy, the port electric grid infrastructure remains virtually unchanged. Rather than installing additional electrical capacity to the ports, an onshore Corvus Energy 410kWh ESS comprised of 63 AT6500 Liquid-Cooled modules was installed on both sides of the route, each providing near instantaneous transfer of power to the vessel ESS.

Emission Free by Design

Norled AS, MF Ampere



The emission free MF Ampere is a new build, and has been designed in catamaran style with two efficient aluminum hulls to reduce resistance in water compared to a traditional hull design. The new vessel weighs half as much as other ferries operating the route.

    Passengers, crew and residents of the picturesque villages of Lavik and Oppedal at either end of the crossing will appreciate the ferry’s missions-free and near-silent operation. Since the ferry is run entirely on battery power, it does not emit greenhouse gases or particulates. The vessel’s batteries are recharged using hydroelectric power from the existing electric utility grid infrastructure in each village, further minimizing the impact of the ferry service.

    Corvus Energy Storage System ESS Benefits:
    • Eliminate onboard fuel consumption
    • Zero emissions
    • Low noise
    • Reduced maintenance
    • Rapid return on investment
    • Improved redundancy
    • Reduced port infrastructure costs for the project.
