Enhanced electric operation and battery durability (ZEWT Partnership)

Expected Outcome:Project outputs and results are expected to contribute to all the following expected outcomes: Demonstrate autonomy, of at least 150 nm (or 277.8 KM for inland navigation) using electrical storage as the only energy source, while allowing rapid in-route zero-emission replenishment. Increase the power output, providing beyond 5 MW as peak propulsion power with corresponding grid capacity. Improve systems to increase the number charging cycles combined with high-power charging to suit the operation needs of different ship types and services. Identify the operating profiles and business cases for which electric powered shipping will bring significant improvements taking into account the priorities and provisions of the Fitfor55 package, especially FuelEU Maritime, Naiades III, AFIR and RED. Develop solutions fitting different ship types and their operational profiles and provide roadmaps for replication. Address the degradation and failure in specific maritime operating conditions. Improved lifetime and safe use of batteries in waterborne transport by addressing the operation profiles, degradation and failure modes associated with unique waterborne transport operating conditions. Scope:This topic aims to improve the suitability of fully-battery-electric operation of ferries, short sea shipping, offshore and inland vessels, considering the services they provide, their operation profiles and the possibilities to interact with charging infrastructure. Aspects like increasing the autonomy range of operation and fast charging are a crucial element for short sea shipping and inland routes with short docking periods. Fast charging may also put added strain on batteries in terms of output and durability. Optimization of the onboard electrical architecture and battery chemistry as well as optimized battery monitoring and management systems and more extensive training of crew can to some extent address this challenge. Life cycle aspects should be considered b
