Recent targets have increased pressure for the maritime sector to accelerate uptake of clean fuels. A potential future fuel shipping is hydrogen, however there a common perception that volume requirements this are too large deep sea shipping. This study has developed range techniques accurately simulate hydrogen case vessel. Hydrogen can use cells, which achieve higher efficiencies than combustion methods, but may require battery hybrid system meet changes in demand. series novel models different cell types and other technologies been developed. The used run dynamic simulations energy setups. Simulations tested against power profiles from real-world data establish minimum viable setup capable meeting all demand vessel, degree accuracy previously achieved. Results showed was with liquid storage, 105.6 MW PEM stack 6.9 MWh batteries, resulting total size 8934 m3. Volume requirement results could then be compared concepts such as systems using ammonia methanol, 8970 m3 6033 respectively.
