First zero emission vessel in operation

This ferry is a revolution, but the passenger hardly notice it. The passage is made without a sound as the ferry crosses 2 nautical miles from one side of the Sognefjord, the largest fjord in Norway, to the other.

The ferry is 81 meter long and 21 meter wide and can carry 120 cars and 360 passengers. The engine room and the bridge is totally different from other ships. The engine is just an electric engine and the main instrument is the charging indicator.

The batteries weigh 10 tonnes in total and has a capacity of 1000 kWh (kilo Watt hours). The passage takes 20 minutes and the batteries are charged during the 10 minutes the ferry stays docked on each side.

The mooring is made by suction to minimize the energy consumption in port. Normally a ferry would use its engine to push against the dock, but with the suction mooring this is no longer necessary.

The ferry is charged by cable. An onshore battery is installed on each side for fast delivery of power to the ferry battery.

The ferry is operated by Norled, a sister company of Nor Lines, the Norwegian shipping line.

The employment of battery-powered ships is still in early stages. However, this technology will become increasingly attractive as the price of batteries continue to fall.
