Modern marine diesel engines operating on conventional marine fuels are unable to further reduce the adverse impact of ship emissions on the environment. Integration of a solid oxide fuel cell (SOFC) and internal combustion engine (ICE) equipped with an underwater exhaust (UWE) can provide the opportunity for mitigating ship emissions and improving energy efficiency. However, numerous integrated system variables such as fuel utilization, engine fuel composition, load-sharing etc. can significantly impact SOFC and ICE operation and, therefore, affect the feasibility and performance of the SOFC-ICE power plant. Moreover, presence of high and fluctuating back pressure due to an UWE can negatively impact engine operation and its performance limits. By investigating these challenges and more, the research presented in this dissertation aims to pave the way for the next generation of extremely efficient prime movers onboard ships, operating on alternative marine fuels, with ultra-low emissions.
