“…Compared to other types of fuel cells, SOFCs have a high electrical efficiency of about 50%, a high fuel-to-electricity efficiency, and the capacity to use a wide range of fuels. The use of SOFCs in large ships [63], where size and heat management are less of an issue than in cars, is possible, although PEM fuel cells are still being investigated for such applications [64,65]. SOFCs are a practical choice for zero-emission sea transportation because of their great electrical efficiency and fuel adaptability.…”

Solid oxide fuel cell (SOFC) systems are spreading worldwide and, for limited applications, also in the transport sector where high power rates are required. In this context, this paper investigates the performance of a six-cell SOFC stack by means of experimental tests at different power levels. The experimental campaign is based on two different stages: the heating phase, useful for leading the system temperature to approximately 750 °C, and the test stage, in which the experimental activities are properly carried out with varying input parameters, such as the DC current load. In addition, a detailed post-processing activity is conducted to investigate the main performance that could be used in the scale-up processes to design and size a SOFC-based system for transportation. The experimental results concern the electrical power, which reaches 165 W, roughly 27 W for each cell and with 52% electrical efficiency, as well as the theoretical thermal power and efficiency, useful for cogeneration processes, with maximum values of 80 W and 25%, respectively, achieved at maximum load. This discussion then shifts to an in-depth analysis of the possible applications of SOFCs in sustainable mobility, particularly in the maritime and aviation industries. The complexities of the issues presented underscore the field’s multidisciplinary nature, ranging from materials science to system integration, and environmental science to regulatory standards. The findings presented could be useful to scientists, engineers, policymakers, and industry stakeholders working on the development and commercialization of SOFC systems in the sustainable transportation sectors.

“…Nevertheless, the efficient storage and transportation of hydrogen pose critical obstacles to fully unlocking its potential. Conventional storage methods, including liquid and gaseous states, suffer from limitations in terms of stability and volumetric constraints. − Thus, there is an urgent need to explore alternative approaches. In this context, metal hydrides have emerged as highly promising candidates for solid-state hydrogen storage. , These materials exhibit enhanced stability and offer an improved energy storage capacity.…”

Efficient hydrogen storage is crucial for realizing the potential of hydrogen as an alternative energy source. Metal hydrides, particularly MgH 2 , have shown promise due to their stability and high storage capacity. However, their high operating temperatures pose challenges. Doping MgH 2 with elements such as Be and Ca is strategically explored to improve performance. This study investigates how dopant type, concentration, and configuration influence the particle size effect on hydrogenation/dehydrogenation reaction thermodynamics. It is revealed that both Be and Ca dopants, irrespective of their configurations (whether positioned on the surface or within the subsurface), enhance the reduction in the reaction temperature of MgH 2 caused by the particle size reduction. This impact is more pronounced for Be dopants compared to Ca dopants. In a similar logic, subsurface doping scenario is better for pronouncing this impact enhances than surface doping scenario. Further investigation highlights that the destabilization of MgH 2 , which is induced by Be/Ca dopants, is primarily attributed to the electronic localization of the local Mg−Be/Ca environment, leading to a reduction in the dehydrogenation reaction temperature by weakening the Mg−H bonds. These findings provide valuable insights into reducing reaction temperatures in metal hydrides, crucial for practical hydrogen storage applications.

“…In 2018, MEPC 72 adopted the Initial IMO Strategy on Reduction of GHG Emissions from Ships (hereinafter the Initial Strategy) [ 23 ]. Levels of ambition directing the Initial Strategy mainly includes: (1) reducing the carbon intensity of international shipping by at least 40 % by 2030, pursuing efforts towards 70 % by 2050, compared to 2008; (2) reducing the total annual GHG emissions from international shipping by at least 50 % by 2050 compared to 2008 [ 10 , [24] , [25] , [26] , [27] , [28] , [29] ]. In MEPC 76, the Operational Carbon Intensity Indicator (CII) was proposed as an operational measure to achieve the carbon emission reduction target of the shipping industry [ 15 ].…”
