Energy transition will reshape the power sector, and hydrogen is a key energy carrier that could contribute to energy security. The inclusion of sustainability criteria is crucial for the adequate design/deployment of resilient hydrogen networks. While cost and environmental metrics are commonly included in hydrogen models, social aspects are rarely considered. This paper aims to identify the social criteria related to the hydrogen economy by using a systematic hybrid literature review. The main contribution is the identification of twelve social aspects which are described, ranked, and discussed. "Accessibility", "Information", "H 2 markets", and "Acceptability" are now emerging as the main themes of hydrogen-related social research. Identified gaps are e.g., lack of the definition of the value of H 2 for society, insufficient research for "socio-political" aspects (e.g., geopolitics, wellbeing), scarce application of social lifecycle assessment, and the low amount of works with a focus on social practices and cultural issues. [Display omitted] • Twelve social aspects related to the hydrogen economy have been identified. • A systematic hybrid literature review (bibliometric and structured) was used. • Useful for sustainability modellers, researchers, policymakers, stakeholders, etc. • Accessibility, Information, H 2 markets, and Acceptability are popular topics. • Gaps, challenges, and perspectives are identified by a multidisciplinary team.

Several roadmaps and international projects are interested in the development of the hydrogen economy for the transportation system. Yet, the development of a hydrogen economy suffers from a lack of infrastructure to store and supply H2 fuel to the refuelling stations, while at the same time, hydrogen can be just seen as one alternative among others to compete with the current fossil fuels. To determine if hydrogen is a competitive option, many scenarios must be assessed considering not only the cost as the target to determine the feasibility but, also environmental and safety objectives. This work is focused on the design of a hydrogen supply chain for deployment scenarios in the Midi-Pyrénées region in France based on multi-objective optimization. Specific constraints related to the energy sources have been integrated and a multi-period long-term problem is examined (2020-2050). Two solution strategies will be implemented to solve this multi-period problem: a global optimization through e-constraint method and a sequential optimization through lexicographic and e-constraint methods. The consideration of different geographical scales and the impact of the initiation step in the development of a sustainable supply chain have been highlighted. [ABSTRACT FROM AUTHOR]
