European and national maritime regulations, aimed at promoting navigation powered by alternative fuels, highlight the need to explore the adoption of various alternative fuel options for maritime transport. This assessment should consider both technical and practical aspects, particularly for freight and passenger services, within the national context in which the sector operates. This document provides a detailed analysis of what is available on the market and the expected results between 2030 and 2050 for the conversion of routes using alternative fuel vessels, both in terms of investment and operational costs. Assessments of vessel fuelling needs were conducted, identifying the potential of different fuels on several key Italian routes, reconstructing their technical characteristics and considering the uncertainty associated with potential changes in fuelling costs (over the life of the vessels) and technological progress.
