Electrification of Commercial Vessels: Pilot Projects and Open Issues

This paper presents a brief overview of some of the most recent pilot projects on vessel electrification, with particular reference to ferries and off-shore vessels. Firstly, the paper resumes the main technological improvements, which enable marine electrification and mainly regard power electronics and electric propulsion systems. Subsequently, the focus is on the description of some pilot projects, grouping them into two main categories, namely ferries and off-shore vessels, which are characterized by different usage and, thus, electrification needs. In conclusion, main features, challenges, and outcomes of each project are highlighted, as well as the overall pending issues, final remarks and future developments.
