Reduction of fuel consumption and lowering harmful gas emissions belong to the category of most important research topics in marine transportation. The former issue is important for all ships, while the latter one is even more emphasized for the vessels operating within highly inhabited areas like short-sea or inland waterway vessels. This paper considers technical, environmental and economic aspects of implementation of alternative power system configurations in the Croatian coastal shipping sector with respect to short- and long-term emission reduction targets, where existing diesel engine-powered Ro-Ro passenger vessel is taken as a test case. In this sense, operating profile of the considered ship and its power needs are analysed and viability of use of alternative powering options is considered. In the analysis, the features of the Croatian energy sector are taken into account. Appropriate sensitivity studies of economic indicators with respect to input parameters are performed. The obtained results show that beside reduction in greenhouse and harmful emissions, the electrification of the considered ship leads to the financial savings over its lifetime. Although Croatian case study is considered, the methodology is applicable generally, but the conclusions will be case-specific, depending on the ship technical and exploitation performance and characteristics of energy sector of the considered country.
