Increased social awareness on the greenhouse gases led to climate agreements setting their strict reduction targets. In order to achieve decarbonization of the shipping industry, some technical measures can be applied, such as replacement of classical ship power system with diesel engine as a prime mover with some alternative solution. This paper investigates the applicability of alternative power system configurations that can be implemented on board passenger and cargo ships from Croatian inland waterway fleet. The environmental impact of three different potential power system configurations (diesel engine-powered ship, battery-powered ship and photovoltaic cells-battery-powered ship) was investigated through the Life Cycle Assessment (LCA) by means of GREET 2019 software. The comparison identified the photovoltaic cells-battery-powered ship configuration as the most environmentally friendly power system configuration.
