Stockholm shipping company Waxholmsbolaget has launched its first hybrid ice-going passenger ferry equipped with a hybrid electric Danfoss Editron marine system to cut fuel usage and emissions.

The 27.5m vessel, designed and built by Baltic Workboats to serve the Stockholm archipelago, operates with two diesel engines and a battery pack. With good weather conditions, the ferry can operate with one diesel engine and the battery pack system, further minimising emissions.

The Danfoss Editron marine system consists of two hybrid drivetrains with permanent magnet electrical motors and generators and is half the size of a conventional, diesel-electric propulsion system.

The hybrid propulsion system is integrated into a single common unit controlled by Baltic Workboats’ monitoring and alarm system. The vessel is also equipped with an exhaust cleaning elective catalyst reduction system to further reduce emissions.
