Wind-assisted, electric, and pure wind propulsion - the path towards zero-emission RoRo ships
Paper in proceeding, 2021

Electrical and wind propulsion, together with the usage of shore-based energy stored in batteries and renewable energies harnessed onboard, can lead the way towards zero-emission ships. This study presents and compares wind propulsion solutions and battery storage possibilities for a RoRo ship operating in the Baltic Sea. The ship energy systems simulation model ShipCLEAN is used to predict the performance of ships with alternative propulsion and energy storage systems in real-life operating conditions. The study showcases how ships can be transferred from a conventional, diesel-powered ship to a zero-emission ship. For the zero-emission ship, all energy needed for auxiliaries and propulsion is taken from renewable sources onboard or from batteries. Challenges and opportunities, as well as necessary adaptions of the route and logistics, are discussed. Results of the study present which wind propulsion technology is the most suitable for the example RoRo ship, and how the installation of suitably sized battery packs for zero-emission operation affects the cargo capacity of the ship.
