Ferry operator Stena Line has embarked on a project to test out plug-in hybrid technology on the combined passenger and freight ferry Stena Jutlandica through the installation of a 1MWh capacity battery from Callenberg Technology Group.
The project will be carried out in three steps with results potentially applicable to other vessels within Stena Line’s fleet of 38 vessels.
In step one, the focus will be on switching to battery power for bow thrusters and maneuvering when berthing in port.
Step two will see an extended battery operation through connection to the propellers, enabling the Stena Jutlandica to operate on electricity for approximately 10 nautical miles (equal to the distance between Göteborg and Vinga Lighthouse).
In step three, battery capacity will be further expanded enabling a vessel to operate for approximately 50 nautical miles on electricity (which corresponds to the distance between Gothenburg and Frederikshavn).
The ‘step’ approach will provide Stena Line with important testing opportunities to gather data and knowledge about the future potential use of electrical power.
Technical solutions are being developed in partnership with Stena Teknik, who is working collaboratively with academia, government and a range of key strategic suppliers.
The project has already received a lot of positive feedback, and the first phase is being supported and co-funded by the Swedish Maritime Administration and the EU.
“Sustainability is very high on our agenda and we are constantly evaluating new ways to reduce our impact on the environment,” says Stena Line CEO Niclas Martensson.
“From 2015, for example, methanol has been part of the fuel mix on the Stena Germanica, which operates between Gothenburg and Kiel, and we also run around 300 different energy saving projects to help us achieve our goal.
“As both the size and cost of batteries decreases, battery operation is becoming a very exciting alternative to traditional fuels for shipping, with the added prospect of emissions to the air being completely eliminated.”

Top three positive movers in 2021 were Hong Lam Fuels Pte Ltd (+14); Sirius Marine Pte Ltd (+12); and TFG Marine (+11); according to the latest data from the Maritime and Port Authority of Singapore.
Webinar will offer delegates insights on the prevention of operational issues when using VLSFOs, along with an update on biofuels and bunker fuel quality trends for 2021 and its forecast for the current year.
Heating VLSFOs to prevent cold flow issues causes issues related to distillate ageing, and there is a gentle balance to be maintained when handling the product.
Research into n-paraffin distribution of VLSFOs has shown that they not only differ from MGO, but significantly differ from each other as well, states bulletin.
Bunker Holding and Dan-Bunkering have decided not to appeal the city court ruling in the case where the companies were on trial for breaching EU sanctions against Syria, states USTC.
Poll shows market participants think Singapore’s future as a bunkering hub in the near term will be impacted most by growth in alternative bunker fuels and intensifying competition from other ports in Asia.
