Comparative life cycle assessment of battery- and diesel engine-powered river cruise ship

Exhaust gases from marine engines are one of the major causes of marine environmental pollution. Although the researches into ship emissions are more focused on ocean-going vessels, emissions from short-sea and inland navigation also contribute to the global amount of pollutant emissions produced by combustion of fuel oil. While this share is small, short sea and inland ships usually operate in highly populated areas and consequently affect both human health and environment. In order to evaluate the environmental impact of river cruise ship that occasionally operates in Croatian inland waterways, its life cycle assessment (LCA) has been performed. Two different power system designs were investigated, i.e. lithium-ion battery- powered ship and diesel engine-powered ship. The analyses were performed by means of general LCA software GREET 2018, The analysis showed that diesel engine-powered ship emits 46.63 kg CO2- eq/nm, versus battery-powered ship with 20.39 kg CO2-eq/nm.
