The electrification of ferries requires efficient shore infrastructures that include energy supply grids, communication networks, charging systems, energy storage systems, interfacing and monitoring devices. In this context, a lot of research and development efforts have been made in the last decade that are reviewed in this paper. Energy storage technologies, battery charging requirements and their safety parameters are first analyzed. A comprehensive review on shore side infrastructure design and power system architecture are then provided. Different shore to ship interfaces are finally presented along with, some alternative solutions to battery charging stations.
