“…Particularly looking at inland waterways and short sea shipping segments [32], and thanks to demonstrations driven by different EU-funded research projects [33][34][35], fuel cell (FC) systems are gaining more and more interest as a promising solution for maritime applications, as they are characterized by a high efficiency and low level of emissions, noise, and vibrations [35]. For all of these reasons and in accordance with the FC main peculiarities presented in [36,37], the authors already reviewed the recent research development/commercial products of FC systems [35] and investigated the use of FCs onboard different types of vessels, from cruise ships [38] to research vessels [39][40][41].…”

In order to promote low-carbon fuels such as hydrogen to decarbonize the maritime sector, it is crucial to promote clean fuels and zero-emission propulsion systems in demonstrative projects and to showcase innovative technologies such as fuel cells in vessels operating in local public transport that could increase general audience acceptability thanks to their showcase potential. In this study, a short sea journey ferry used in the port of Genova as a public transport vehicle is analyzed to evaluate a ”zero emission propulsion” retrofitting process. In the paper, different types of solutions (batteries, proton exchange membrane fuel cell (PEMFC), solid oxide fuel cell (SOFC)) and fuels (hydrogen, ammonia, natural gas, and methanol) are investigated to identify the most feasible technology to be implemented onboard according to different aspects: ferry daily journey and scheduling, available volumes and spaces, propulsion power needs, energy storage/fuel tank capacity needed, economics, etc. The paper presents a multi-aspect analysis that resulted in the identification of the hydrogen-powered PEMFC as the best clean power system to guarantee, for this specific case study, a suitable retrofitting of the vessel that could guarantee a zero-emission journey.

The International Maritime Organization (IMO) established a challenging global strategy in 2023 to reduce greenhouse gas (GHG) emissions from international shipping by 70% by 2040. Achieving these targets necessitates radical actions, including the use of carbon free fuels and hybrid-alternative propulsion systems. The NEREHYDES (Novel hEat REcovery solutions on board of fuel cell equipped vessels for metal HYDridES storage optimal management) national research project aims to optimize the design and management of a hybrid system with hydrogen fuelled Proton Exchange Membrane Fuel Cells (PEMFC) and diesel Internal Combustion Engines (ICE) on board short-travel ferries for zero-emission operation in coastal and harbour areas. Hydrogen would be stored on board via metal hydrides storage (MH), allowing for the H2 storage at low pressure and close to room temperature.. The new PEMFC - MH system is designed to operate mostly in harbour, while the traditional ICE operates during navigation in open sea. In this way, Waste heat produced by the engine could be stored on board of TES to be then used to properly manage the metal hydrides discharging once in harbour to properly operate the PEMFC: once the PEMFC will be fully operative, the waste heat produced by the FC could be exploited in order to minimize TES size. The study consists of a pre-feasibility analysis for sizing the TES on board based on above mentioned operational strategy of the integrated system (ICE-TES-MH-PEMFC) towards the minimization of the volumes. At this purpose two different type of TES (sensible heat with hot water and latent heat with identified PCM suitable to manage the MH discharge) will be compared, analysing the volume and cost needs for both of them. The study is carried out considering the requirements of a real vessel operating in Stretto di Messina - Sicily (Italy) and its daily travelling routes, aiming to compare the sizing architectures of the integrated system via a heat transfer modelling tool developed by the Thermochemical Power Group (TPG) at the University of Genoa.
