This article investigates the potential of renewable and low-carbon fuel production for maritime shipping sector, using Sweden as a case in focus. Techno-economic modelling socio-technical transition studies are combined to explore conditions, opportunities barriers decarbonising industry. A set scenarios have been developed considering demand assumptions instruments such carbon price, energy tax, blending mandate. The study finds that there industry by marine fuels advanced biofuels (e.g., biomethanol), electrofuels e-methanol) hydrogen. has tremendous resource bio-based hydrogen-based liquid production. In evaluated system boundary, biomethanol presents cheapest technology option while e-ammonia is most expensive one. Green electricity plays an important role decarbonisation sector. results supply chain optimisation identify location sites well trade flows bring where bunker facilities potentially located. Biomethanol cost-effective at price beyond 100 €/tCO2 200 respectively. Linking back pathways, some companies process transitioning towards fuels, thereby enabling niche innovations break through lock-in eventually alter regime, other more resistant. Overall, increasing pressure from (inter)national climate policy-making decarbonise
