The aim of this research is to perform a thermodynamic analysis of an SOFe - gas turbine (GT) hybrid power plant, including economical aspect, so as to examine its appropriateness (through the study of several cases) for marine application on an LNG carrier. Provided the data concerning properties and costs of materials, the developed model is to fit for a wide range of parametric analysis of thermodynamic cycles. This prospect takes into the consideration that SOFe is a promising technology with lots of advantages in comparison to conventional marine combustion engines; it is much more efficient, friendlier to the environment, more fuel flexible and operates under high operating temperatures which enable a successful thermal integration with bottoming cycles (gas turbine cycles) in order to achieve a higher efficiency. In general terms, an LNG carrier has a high energy demand. Through this analysis, it is shown in certain extent the SOFe - GT system can be developed either for the main propulsion of the vessel or the APU (Auxiliary Power Unit). The latter is a more practical possible solution as it is of less exigent energy. The program used for this analysis is divided into two sections; the pre-reforming section and the electrochemical (SOFC) section together with the gas turbine including the cost model as well. Another issue which is examined in this thesis is the fluctuation of charter rates of a specific LNG carrier depending on the size of the investment. The height of the investment is defined by the power output of the SOFe installation. The final results give a theoretical and general idea of the way that this hybrid power plant could be exploited by an LNG carrier implying whether it can be preferred to the conventional combustion engines or not.
