“…The proposed configurations were presented by the authors in previous papers [10,[21][22][23], in which the HRSs were sized for smaller hydrogen capacities (100 and 200 kg/day). In [10,21] in particular, ammonia-based HRSs with hydrogen capacities of 100 kg/day and 200 kg/day were proposed, respectively.…”

“…In [10], the selected power production section was a SOFC unit, and in [21], a PEMFC system was implemented for satisfying the electricity requirements. A biogas-based HRS, characterized by an autothermal reforming (ATR) unit, as the hydrogen production system, and sized for a capacity of 100 kg/day, was studied in [22]. Furthermore, a grid-connected PV plant integrated with an electrolysis unit was examined in [23], where different plant configurations of hydrogen production capacity and electricity were analyzed.…”

In this study, the authors present a techno-economic assessment of on-site hydrogen refuelling stations (450 kg/day of H2) based on different hydrogen sources and production technologies. Green ammonia, biogas, and water have been considered as hydrogen sources while cracking, autothermal reforming, and electrolysis have been selected as the hydrogen production technologies. The electric energy requirements of the hydrogen refuelling stations (HRSs) are internally satisfied using the fuel cell technology as power units for ammonia and biogas-based configurations and the PV grid-connected power plant for the water-based one. The hydrogen purification, where necessary, is performed by means of a Palladium-based membrane unit. Finally, the same hydrogen compression, storage, and distribution section are considered for all configurations. The sizing and the energy analysis of the proposed configurations have been carried out by simulation models adequately developed. Moreover, the economic feasibility has been performed by applying the life cycle cost analysis. The ammonia-based configurations are the best solutions in terms of hydrogen production energy efficiency (>71%, LHV) as well as from the economic point of view, showing a levelized cost of hydrogen (LCOH) in the range of 6.28 EUR/kg to 6.89 EUR/kg, a profitability index greater than 3.5, and a Discounted Pay Back Time less than five years.

“…The critical issues related to the emissions from ships activities have been analyzed in depth in the scientific literature over the years [2][3][4][5][6], promoting the adoption of solutions that enable their reduction. Zero-or low carbon fuels such as diesel, ammonia, hydrogen, biofuels [7,8] and the integration with innovative/alternative energy technologies, could represent good choices for the shipping decarbonization [9,10]. The aim of this paper is to analyze and compare from an environmental point of view different solutions which aims to assures the reduction in terms of CO2eq and NOx with respect to the conventional Heavy Fuel Oil (HFO).…”

According to the International Energy Agency (IEA) reports, the maritime sector was responsible for around 2% of global energy-related Carbon Dioxide (CO2eq) emissions in 2020 (i.e., 714 Mton). Currently, Heavy Fuel Oil (HFO) is used for supplying main and auxiliary Internal Combustion Engines (ICEs) on board ships, therefore it is responsible for local and global pollution. As matter of fact, HFO is contaminated with several different compounds including aromatics, sulfur, and nitrogen, making emission upon combustion more polluting compared to other fuel oils. In order to reduce pollution in maritime sector, the International Convention for the Prevention of Pollution from Ships (MARPOL) has prohibited ships using of HFO in ports. In this purpose, new solutions involving cleaner fuels as well as new propulsion technologies are needed. This paper is aimed to evaluate the environmental advantages that can be reached by replacing the HFO with low emission fuels and alternative power technologies. In particular, three cases have been investigated: i) ICEs fed by diesel, ii) Fuel Cell Systems fed by “Yellow” hydrogen, iii) Fuel Cell Systems fed by “Green” hydrogen. The analysis has been carried out by applying the Well-to-Waves (WTW) method for estimating and comparing the avoided CO2eq and NOx emissions. Moreover, the economic feasibility has been carried out by estimating the investment and operating costs.
