    One of the main barriers to the adoption of fuel cell vehicles (FCEVs) is the limited availability of hydrogen refuelling stations (HRSs). The presence of these stations is crucial in facilitating the provision of fuel for FCEVs, which rely on hydrogen as a source of power generation. Renewable energy sources offer significant advantages for hydrogen production at these stations, as they are environmentally friendly and can reduce costs. In this study, it is provided a techno-economic analysis of an on -site hydrogen refuelling station powered by a hybrid renewable energy generation system using HOMER software in Nigde, Turkiye, and Zaragoza, Spain. Three different power system scenarios were evaluated to refuel 24 vehicles per day for each region throughout the year. The results of the analysis showed that the most optimal system architecture for Nigde was with a solar panel power generation system, with a levelized cost of hydrogen (LCOH) of 6.15 $/kg and the net present cost (NPC) of $6,832,393. The most optimal system architecture for Zaragoza was a wind turbine -photovoltaic panel power generation system, with an LCOH of 5.83 $/kg and NPC of $6,499,723. The annual amount of CO2 emissions avoided by using renewable resources in hydrogen production was calculated as 2,673,453 kg for Nigde and 2,366,573 kg for Zaragoza. The study also found that the cost of hydrogen production increases with decreasing the HRS production capacity. The use of renewable energy generation systems for hydrogen production will enable countries to achieve net -zero emission targets and reduce the need to import fossil fuels to meet energy demands in the transportation sector. The present study makes several contributions towards the achievement of the United Nations Sustainable Development Goals (3, 7, 11, and 13) and has the potential to facilitate the rapid adoption of FCEVs.

    Towards a Sustainability Framework for Hydrogen Refuelling Stations: a Risk-Based Multidisciplinary Approach
    (Italian Association of Chemical Engineering - AIDIC, 2023) Paltrinieri, Nicola; Yamamoto, Toshiyuki; Rusin, Andrzej; Sala, Roser; Liu, Yiliu; Sato, Hitomi; Gokcek, Murat
    Sustainable hydrogen technology is becoming increasingly important as the world moves towards cleaner and more sustainable sources of energy. Hydrogen is a clean and versatile energy carrier that has the potential to play a critical role in the transition to a low-carbon economy. However, to realize this potential, significant technological advancements are needed in the production, storage, and distribution of hydrogen. To achieve these advancements, a multidisciplinary approach is required that involves technical, organizational, social, and economic factors. Sustainable hydrogen technology development is a complex and multifaceted process that requires the integration of various perspectives and expertise. A framework is needed to bring together these perspectives and develop a common approach to assessing risks and opportunities associated with hydrogen technology. This contribution proposes a framework addressing system modelling and analysis issues in clean hydrogen production and storage, with a focus on uncertainties that can impact social, economic, and environmental sustainability of hydrogen production and refueling facilities. By using risk-based performance and degradation models, the framework helps prevent and mitigate accidents and builds organizational safety culture and procedures while better communicating with the public. The framework also identifies optimal operational modes for increasing the feasibility of hydrogen refueling stations, ultimately leading to the development of more efficient, reliable, and lower-cost hydrogen-based technologies. The development of a common risk-based framework promotes sustainable hydrogen technology and identifies new opportunities for growth and collaboration. The framework is developed collaboratively through an international research network. By integrating multiple perspectives and disciplines, the framework can provide a roadmap for the development of sustainable hydrogen technology and create opportunities for future growth and development in the field.
