The main objective of the present MSc thesis is the exhaustive study of literature in the field of utilization of hydrogen as alternative zero carbon fuel and as one of the available means for shipping progressive decarbonization. The work initially provides an overview of the environmental legislation applicable to the shipping sector both at a global level based on the guidelines of the International Maritime Organization (IMO) and at a European level based on the current environmental legislation for the decarbonization of shipping established by the European Union. The methods of hydrogen production, the physical and chemical properties of hydrogen in comparison with other marine fuels and the advantages and disadvantages of hydrogen as an alternative marine fuel are then presented. A broad review of the international literature is then carried out to examine the impact that the use of hydrogen has on the operational performance and emissions of pollutants from marine engines. In the last part of this study, the lifecycle cost of hydrogen is examined through the review of well-to-tank and tank-to-propeller study results.
