Building on previous work, this study elaborates on the use of<br> methanol, ammonia and hydrogen. The total lifetime costs are quantitatively evaluated alongside a holistic evaluation of the<br> societal cost of CO2-emissions in order to determine the point at which the fuel price point of synthetically produced fuels<br> becomes economically viable. Besides this, the impact on ship design is examined using the Ships Power and Energy Concept<br> (SPEC) research tool. Concluding, synthetic fuels produced using renewable energy offer the greatest greenhouse gas<br> reductions, but given their current technological maturity are not yet financially attractive. However, biofuels like biomethanol<br> are a feasible stepping stone to gain experience in the use of alternative fuels on ships. Additionally, as expected,<br> the parametric approach in this study suggests the ship dimensions and displacement will increase, mostly due to the relatively<br> low energy density of the fuels. However, further concept design is required to investigate whether the actual ship design<br> grows, or whether additional volume for fuel is available in the design of these vessels, which are primarily driven in size by<br> the deck space required for their operations. 000007703 542__ $$fCC-BY-4.0 000007703 6531_ $$aalternative fuels 000007703 6531_ $$amethanol 000007703 6531_ $$aammonia 000007703 6531_ $$ahydrogen 000007703 6531_ $$ashort sea shipping 000007703 6531_ $$aSPEC 000007703 7001_ $$aAstley, W.E$$uMaritime Systems Division, Defence Materiel Organisation, Ministry of Defence, Utrecht, Netherlands 000007703 7001_ $$aGrasman, A$$uShip Systems Integration Team, MARIN, Wageningen, Netherlands 000007703 7001_ $$aStroeve, D.B$$uMaritime Systems Division, Defence Materiel Organisation, Ministry of Defence, Utrecht, Netherlands 000007703 773__ $$tConference Proceedings of INEC 000007703 773__ $$jINEC 2020 000007703 789__ $$whttps://zenodo.org/record/4498428$$2URL$$eIsIdenticalTo 000007703 8564_ $$9d49060f5-8efb-4bf4-9667-8a1ebe02b15e$$s987082$$uhttps://library.imarest.org/record/7703/files/INEC_2020_Paper_98.pdf
