Modelling and simulation of a hydrogen-powered passenger catamaran ferry

The work focuses on the modelling of a zero-emission, high-speed catamaran ferry employing a full-electric propulsion system. It addresses the global emphasis on full-electric vessels to align with IMO regulations regarding ship emissions and energy efficiency improvement. Using the AVL Cruise-M software, the research verifies the implementation of an onboard fuel cell power generating system integrated with the propulsion plant, aiming to assess dynamic performance under load variation. The catamaran is 30 meters long and 10 meters wide with a cruise speed of 20 knots. The model includes a 1600 kWe PEM system, fuelled by hydrogen stored in type IV cylinder vessels at 700 bars, and a 2-kWh capacity battery pack. Simulation results show that the battery effectively supports the PEM during the manoeuvring phase, enhancing overall performance and energy economy. The study emphasises that new hydrogen storage systems can make easier the onboard installation and increase the ship’s autonomy.
