Abstract

In order to cope with continuously increasing environmental demands, the maritime sector is investigating alternative solutions for the power generation on board. These solutions include both alternative fuel, such as Liquefied Natural Gas (LNG) and hydrogen, and green technologies, such as fuel cells (FC) and batteries. Although in-port emissions are responsible of a small percentage of the overall emissions, ports constitute sources of concentrated ship harmful emissions, potentially very dangerous for the human health. Moreover,the environmental regulations suggest switching present marine fuels as soon as possible. In this frame, this work investigates innovative solutions for the electric power generation in port for passenger ships in terms of cost and environmental benefits. These can be shore power solutions (such as cold ironing) and on-board solutions (such as dual fuel, fuel cell and others). The results show that some solutions could be more competitive than others according to specific operating conditions. The aim of the study is to identify the most eco-friendly and promising solutions. The cost analysis methodology takes into account the efficiency, fuel costs, operating and maintenance costs and the initial investment costs. The environmental comparison considers the emissions of nitrogen and sulphur oxides, carbon monoxide and dioxide, particulate matter and hydrocarbon.
