Climate change calls for a global concerted action plan. The marine sector which contributes 3% of global emissions is a key sector identified to realize targets set by 196 countries as part of their nationally determined contributions shared to the United Nations Framework Convention on Climate Change as signatories to the Paris Agreement. This paper dives into the role Hydrogen can play as an actor in maritime decarbonization. The value chain of hydrogen from production to utilization is discussed and its corresponding lifecycle emissions for liquefied hydrogen from fossil-based and renewable energy feedstock for a harbor craft use case scenario is illustrated. Our results show the impact of powertrain models on the overall emissions as well as a 66% reduction via the use of renewable energy to produce hydrogen.
