Stena Line has signed a contract with Callenberg Technology Group for batteries to be retrofitted on one of its ferries.
The batteries will have capacity of 1 MWh and be installed on Stena Jutlandica, which operates between Gothenburg and Frederikshavn. The batteries will be used for port operations by Q3 this year.
Stena said it plans to navigate the vessel 50 nautical miles by battery power in future.
“Sustainability is very high on our agenda and we are constantly evaluating new ways to reduce our impact on the environment… As both the size and cost of batteries decrease, battery operation becomes a very exciting alternative to traditional fuels for shipping, as emissions to air can be completely eliminated,” said Stena Line chief executive Niclas Mårtensson.
The battery project will start now and will be completed in stages, said Stena. It said in step one, it is about switching on battery power for bow thrusters and manoeuvring when berthing in port. In step two, an extended battery operation will be connected to the propellers, meaning Stena Jutlandica can be operated on electricity within around 10 nautical miles, equal to the distance between Göteborg and Vinga Lighthouse.
In step three, battery capacity will be further expanded and the vessel will operate about 50 nautical miles on electricity corresponding to the distance between Gothenburg and Frederikshavn.
The objective of accomplishing this in several steps is to test and gather knowledge about electrical operation along the way. If the project is successful, battery operation may also be applicable to other vessels in the Stena Line fleet of 38 vessels.
The technical solutions are being developed together with Stena Teknik, which co-operates with the academic world, authorities and various suppliers. The project has been received “very positively”, and the first phase is supported and financed equally by the Swedish Maritime Administration and the EU.
