9. Fast Charging for Marine Transportation

Shipping via sea or ocean is considered more economical than road shipping with reduced GHG (greenhouse gas) emissions. Maritime electrification requires effective charging infrastructures. The penetration of renewable energy systems in maritime will support the transportation electrification in maritime applications. In order to expand maritime electrification, integrated charging infrastructures should be implemented effectively. There are benefits to integrating charging infrastructures for maritime with waterfront energy systems where implementation costs are reduced while reducing GHG emissions. This chapter discusses the analysis and functional modeling of the hybrid energy system for maritime transportation electrification as integrated with waterfront applications. Hybrid energy system design is discussed where renewable and energy storage technologies are integrated to meet load profiles for maritime charging and waterfront energy supply demands. Model parameters are identified and utilized to define suitable configurations of the integrated charging station with maritime ships based on different ship categories and demand profiles for different routes. Optimization techniques and practices are discussed using the charging station, ship, and grid interface parameters. A global and local optimization framework is explained using performance measures for each integrated system component. Research and innovation approaches are discussed to support the research chain from academia to industry.
