Stena Line’s Stena Jutlandica has successfully completed its first month of operation as a battery hybrid vessel. The conversion project on the Stena Jutlandica is being carried out in measured steps. The first step underway is testing the switching to electrical power its effect on the vessel's maneuverability and power to the bow thrusters when the ship is in port. The environmental savings from using battery power for reduced generator usage and maneuvering in port amounts to about 500 tons of fuel, 1,500 tons of CO2. This in turn corresponds to the annual emissions from approximately 600 cars.
The next round of tests will be connecting battery power to two of the four primary machines, which means that the Stena Jutlandica will be able to run on electrical power for about 10 nautical miles inside the Gothenburg archipelago out to Vinga Lighthouse. In step three, all four primary machines will be connected to the batteries and the ship will be able to cover the 50 nautical miles between Sweden and Denmark solely on electrical power. The technical solutions in the first step have been developed by Stena Teknik in collaboration with the Callenberg Technology Group, with half of the funding for the project coming from the Swedish Transport Administration and the EU.
