Exploring the Hydrogen Transition Within the Maritime Value Chains

The maritime industry is experiencing a transition towards the adoption of sustainable alternatives to traditional fossil fuels. The focus is on hydrogen due to its emergence as a feasible solution to the problem of pollution across the industry. The context comprises four value chains: those pertaining to the design, production, and management of fuel, ships and infrastructure (i.e., port and bunkering facilities); as well as the value chain associated with maritime operations (i.e., sea voyage between two ports). To successfully introduce hydrogen in maritime operations, the industry must be aligned in terms of the design and management of fuel, ships and infrastructure to accommodate the necessary changes. The study investigates the relationships within and between value chains, which can either support or hinder the transition. To this aim, a systematic literature review is performed. The analysis of 42 articles provides insights at the intersection of these value chains. The study identifies the decisional variables that will have implications on the industry at large, including the storage form of the fuel and related requirements, the design of the ship and its fuel consumption, and the availability of suitable supporting infrastructure. Finally, the aim is to examine current research trends, highlight any shortcomings, and identify future research directions.
