Hydrogen Storage and Materials

This paper aims to perform a systematic review, with a bibliometric approach, of the techno-economic evaluation studies of hydrogen production. To achieve this objective, a comprehensive outline of hydrogen production processes from fossil and renewable sources is presented. The results reveal that electrolysis, classified as water splitting, is the most investigated process in the literature since it contributes to a reduction in greenhouse gas emissions and presents other advantages, such as maturity and applicability, energy efficiency, flexibility, and energy storage potential. In addition, the processes of gasification, classified as thermochemical, and steam reforming, classified as catalytic reforming, are worth mentioning. Regarding the biological category, there is a balance between research on photo fermentation and dark fermentation. The literature on the techno-economic evaluation of hydrogen production highlights significant gaps, including a scarcity of comprehensive studies, a lack of emphasis on commercial viability, an absence of sensitivity analysis, and the need for comparative analyses between production technologies.
