The environmental impact of fuel cells for auxiliary power generation onboard a passenger ship trafficking Oslo-Kiel was studied through the use of LCA. Five Solid Oxide Fuel Cells with Gas Turbines modules of 500 kW each, 2500 kW total was investigated. The LCA comprises manufacture, operation with four fuel supply options and decommissioning (qualitatively only). The most environmentally advantageous scenario is operating using LNG produced in Norway. This is due to fewer and shorter fuel transport links. Operation using LNG supplied from sources outside the EU is the least environmental friendly option. As operation of fuel cell systems emits very little NO(x) and SO(x), the fuel supply chain carries the greater potential for photochemical oxidation and acidification. However, operation of the SOFC-GT still emits the larger amount of greenhouse gases.This study is limited by the scope, findings and quality of the other studies within the FCSHIP project, impacting the system boundaries as well as the data quality. The conceptual design for a fuel cell auxiliary system is used as the design basis together with the findings for fuel supply and operational stages.
