This presentation will examine the advances and hurdles in the electrification of high-speed passenger ferries. We will explore recent case studies showcasing incremental progress in speed and capacity, analyze evolving lithium-ion battery technologies – including the implications of the NMC811 chemistry – and discuss the trade-offs between energy density and charge rates. A key focus will highlight lessons learned from past incidents, emphasizing safety considerations in battery system design. Also covered will be the potential of direct current (DC) rapid charging to support these high-speed operations. By shifting key charging infrastructure shoreside, DC charging can enable significant onboard weight reductions and faster turnaround times. We will compare marine DC propulsion topologies to those of automotive and look at battery swap as a way around charging rate limitations. Drawing from EBDG’s work helping ferry operators to make the transition to zero-emission ferries, this session will provide valuable insights into the future of high-speed electric passenger vessels. Attendees will gain a deeper understanding of the evolving technologies, regulatory considerations and engineering solutions that will shape the next generation of maritime electrification.
