Abstract
Ships play a crucial role in global transportation, yet they significantly contribute to greenhouse gas emissions. The International Maritime Organization targets net-zero emissions by 2050, necessitating cleaner energy solutions. Solid oxide fuel cells (SOFCs) offer higher efficiency than diesel engines, reducing carbon emissions and toxic pollutants. This dissertation explores the integration of SOFC systems into ships, assessing fuel options, efficiency, and operational challenges. Experimental studies examine SOFC performance under ship motions, highlighting the need for design adaptations. Thermodynamic analysis compares various fuels, identifying methane and ammonia as optimal choices based on efficiency and heat demand. A megawatt-scale SOFC system is conceptually designed to enhance power density. Hybrid power plant simulations demonstrate significant emission reductions, especially for auxiliary loads. The study concludes that SOFCs are viable for multiple ship types, particularly those with stable load profiles. Further advancements in alternative fuels and system design are essential for widespread adoption.
