Win-win for district heating connection

A


novel shore-side connection to the district heating system at the Port


of Gothenburg enables ships at the quayside to shut down their boilers, reducing oil consumption and running costs. It’s the first time ships in regular


service have been connected to district heating systems. Launching the system, Stena Line chief executive Carl-Johan Hagman


said: “Stena Line is working consciously toward creating the eco-friendly shipping of the future and we are a world leader in this area. The district heating initiative has made our business operations even more sustainable in the long term.” Stena Danica, which operates


between Gothenburg and Frederikshavn in Denmark, has been fitted with a district heating connector. This means that the oil-


fired boilers can be shut down at the quayside. The remainder of the power supply on board is provided through a shore-side power connection. This allows the auxiliary engines to be shut down completely when the ship is at the quayside, reducing local emissions. “Stena Line’s terminals are


centrally located in Gothenburg,” said Hagman. “The district heating connection is a means


of combining logistics, industry and housing in central locations. It is modern community planning at its best and it is what makes Gothenburg unique.” By transferring to district


heating, carbon dioxide emissions are reduced by almost 500 tonnes per year, equivalent to the emissions from 246 cars or the energy used by 260 detached houses.


“Shipping is facing major


environmental challenges and this is an excellent and creative way of reducing local emissions. Stena Line will also begin using methanol as a fuel next year, which is a project that we at the Port of Gothenburg fully support,” said Jill Söderwall, energy business chief at the Port of Gothenburg. A container at the quayside


contains a heat exchanger that exchanges district heating water with the vessel’s heating system. In Stena Danica’s engine room the hot water is exchanged with the vessel’s existing heating system with the aid of four on-board heat exchangers.
