Stena Line plans to start operating two fossil-free battery powered ro-pax vessels between Gothenburg and Frederikshavn in Denmark no later than 2030, according to CEO Niclas Mårtensson, speaking to industry collaboration project Tranzero Initiative.

The Transzero project aims to speed up the transition to fossil-free fuels in the transport sector, and Stena Line is joining with Volvo Group, Scania and the Port of Gothenburg to bring about a significant reduction in carbon emissions linked to Gothenburg port, cutting emissions by 70% by 2030.

Mårtensson said: “We now move from vision to vessel with the battery powered vessel Stena Elektra. Within a year we will present the outline specifications and at the latest by 2025 we plan to order the first vessel. This will be a huge step towards fossil free shipping.”

Stena Elektra will be the first fossil free ro-pax vessel of its size, measuring about 200m and with capacity for 1000 passengers with 3000 lane metres vehicle space. The vessel will be built in high tensile steel to lower the weight and increase efficiency and it is estimated the vessel will run on battery power for about 50 naut mile, the distance between Gothenburg and Frederikshavn. The battery capacity will need to be approximately 60-70 MWh and the vessel will be charged in port. Stena Line is looking into combining the electrification with other alternative fossil free fuels such as fuel cells, hydrogen and bio methanol for longer range.

”The electrification of shipping has only just began. We see a great potential for both battery hybrids and battery powered vessels on several of our short-sea shipping routes in the future. But, it takes more than the electrical ships, we also need to develop the infrastructure and charging possibilities in the ports and terminals in the same pace and that is a reason why collaborations projects like this are so important, said Mårtensson.

Since 2018 Stena Line has operated the battery hybrid vessel Stena Jutlandica on the Gothenburg-Frederikshavn route, using battery power for manoeuvring and powering the bow thrusters when the ship is in port. The batteries are charged with green shore power in port of Gothenburg as well as during operation and in total the CO2 emissions are lowered by 1,500t/yr.
