The main idea in this pre-study is to look at the option to replace the combustion diesels engines for electricity production with fuel cells, when the ship Stena Jutlandica is in Gothenburg harbour. This to prepare for a potential second phase were such a system may be built. The electricity is needed for lamps, air-condition and other necessary functions in the boat, but also for running the fans during on and off loading. In this study the main goal is to achieve a description of a possible fuel cell system; how it functions, how it can be adjusted to the boat application and what such a system might cost. The project is carried out by Swedish partners and as the fuel cell technology is still quite new most of the system projecting work is done for the first time in Sweden.
