The Stena Line-owned passenger ship Stena Danica is the world’s first ship in regular service connected to a district heating grid.
Stena Danica has a capacity of 2275 passengers and operates the route Gothenburg – Fredrikshavn 650 times each year. Through a ground breaking demonstration project, it is connected to the local district heating grid when it arrives to port in Gothenburg instead of being heated by the previously used oil fired boilers.
It is estimated that the switch from light oil to district heating will reduce the CO2 emissions by as much as 500 tonnes per year (-60%). It will also contribute to a significantly better air quality in Gothenburg as it reduces the ships’ levels of SOx and NOx with more than 90 % annually. Last but not least it will also reduce the levels of noise in the neighbourhood.
This pioneering demonstration scheme is part of the CELSIUS project, which is funded by the EU’s Seventh Framework Programme for research. The demonstration project has been carried out in close cooperation between Göteborg Energi, Stena Line and the City of Gothenburg.
