An overview of hydrogen production via reforming from natural gas

Purpose. To provide an extensive analysis of hydrogen production and the major benefits as well as challenges in the hydrogen production from natural gas. Methodology. The systematic review approach was used in this study. The first stage in a holistic evaluation is to find related significant works and specific concepts, and then apply them to search phrases and syntax. A thorough search is implemented in the Web of Science, Google Scholar, Science Direct, and Scopus databases in the English language. Moreover, the publication time of the papers is also limited in the period from 2010 to September 2023. Findings. The literature review revealed that natural gas reforming is the most prevalent technique for producing hydrogen. The obtained results also showed that the approach based on automatic thermal reforming is less common than the one that uses natural gas to create hydrogen by steam reforming. Additionally, natural gas steam reforming has the most harmful environmental influences with regard to abiotic degradation, potential global warming, and other influence types. Originality. This analysis offers an in-depth overview of how hydrogen is produced from natural gas as well as the benefits and limitations of the reforming method for producing hydrogen. Practical value. From the literature review, it was found that the current preferred method for creating hydrogen is steam natural gas reforming. In addition, this review provides a comprehensive and useful resource for study, scientific advancement, and advancement in the disciplines of creating hydrogen.
