Hydrogen vs. Batteries: Comparative Safety Assessments for a High-Speed Passenger Ferry

Batteries and hydrogen constitute two of the most promising solutions for decarbonising international shipping. This paper presents comparison between a battery proton-exchange membrane fuel cell version high-speed catamaran ferry with main focus on safety. The systems required each are properly sized fitted according to applicable rules, their impact overall design is discussed. Hazards both designs were identified; frequency consequence indexes them input qualitatively, following Novel Technology Qualification SOLAS Alternative Designs Arrangements, while certain risk control options proposed in order reduce risks concerned accidental events. highest ranked analysed by quantitative assessments PyroSim software. gas dispersion analysis performed indicated that it crucial leakage room be stopped within 1 s after being detected prevent formation explosive masses under full pipe rupture 33 mm diameter, even 120 air changes per hour.
