The maritime transport industry contributes to almost 3% of the global CO2 emissions. In particular, the Inland Waterway transport is a critical sector since it also impacts on the local pollution of many European cities, among which Paris, that over the past few years has pledged to phase out petrol-powered mobility by 2030, investing in electric and hydrogen vehicles. In this context, the objective of this master thesis, was to develop a feasibility study of a Hydrogen Refuelling Station to refuel mainly hydrogen powered Inland Waterways ships in the Seine river, in the framework of the Interreg North-West Europe H2SHIPS project.
