Comparison of Shipboard Energy Storage Systems for Maritime Propulsion

Electrification is a key technology to reduce maritime emissions. The International Maritime Organization (IMO) wants to reduce annual greenhouse gas (GHG) emissions from maritime transport by 50% by 2050 compared to 2008. Electrification is one of the solutions to reach this target. However, maritime electric propulsion is not yet mature. PoliTO is involved in the research of innovative maritime battery systems with the task of developing power electronics converters to interface the battery systems to the shipboard distribution network.

This work is carried out in the framework of the European Project H2020 SEABAT, with the goal of developing a modular full electric maritime hybrid battery concept to substantially reduce the costs of large waterborne battery systems for over 1MWh: https://seabat-h2020.eu/
