Zero emission targets, as long-term global goals for climate protection, and the IMO GHG emission reduction strategy, fully involve ship design in a complex process of research and technological innovation. This paper proposes a feasibility study of a hydrogen fuel cell powered high-speed passenger craft. The passenger craft is intended to operate in the Amalfi coast, carrying 220 passengers at a route speed of 20 kn. The dimensions of the passenger craft are 30 m Length, 10 m wide. The feasibility study of the implementation of a PEM fuel cell propulsion system, has been structured ensuring the mutual consistency between all the subsystems: propulsion plant, energy storing and payload. Moreover, critical aspects related to safety has been analyzed according to the updated regulations.
