“…Due to the sensitivity of the hydrogenase enzyme to oxygen, many researchers have studied protein engineering as a tool for improving the oxygen tolerance of [FeFe]hydrogenases [151]. Furthermore, genetic modifications mediated using the CRISPR-Cas technique, mainly to improve substrate utilization and H 2 yields in several species of the genus Clostridia, also emerge as a potential alternative [158].…”

Palm oil, the main vegetable oil produced globally, serves diverse purposes, ranging from cooking to the production of processed foods, cosmetics, and biodiesel. Despite contributing significantly to the economies of major producing nations, the escalating production of palm oil raises serious environmental concerns, including deforestation, biodiversity loss, and various forms of pollution. Palm oil mill effluent (POME), a byproduct of palm oil extraction, poses a severe environmental threat when left untreated. As an eco-friendly alternative, anaerobic digestion in controlled bioreactors has emerged, offering simultaneous POME treatment and biofuel generation, particularly hydrogen, with high energy efficiency. This review explores the challenges and opportunities associated with biohydrogen production from POME. Key considerations involve optimizing parameters through pretreatments, nanoparticle incorporation, defining optimal bioreactor conditions, determining hydraulic retention times, and integrating multi-stage processes like dark fermentation followed by photofermentation. This review also emphasizes the significance of sustainable practices and economic analyses in shaping the future of hydrogen production from POME, positioning it as a pivotal player in the palm oil industry’s circular economy and the global energy transition.

“…The line of investigation that the academic community has developed in hydrogen production by fermentation from biomass points in promising directions. The improvement of fermenting microorganisms [81][82][83] to increase the production potential is a future field of research. To improve hydrogen production, future research may converge on the identification of adapted microorganisms, allowing a more comprehensive substrate exploration [84][85][86], in particular, the search for more sustainable solutions for an immense variety of wastes from industrial production processes.…”

Fermentation is an oxygen-free biological process that produces hydrogen, a clean, renewable energy source with the potential to power a low-carbon economy. Bibliometric analysis is crucial in academic research to evaluate scientific production, identify trends and contributors, and map the development of a field, providing valuable information to guide researchers and promote scientific innovation. This review provides an advanced bibliometric analysis and a future perspective on fermentation for hydrogen production. By searching WoS, we evaluated and refined 62,087 articles to 4493 articles. This allowed us to identify the most important journals, countries, institutions, and authors in the field. In addition, the ten most cited articles and the dominant research areas were identified. A keyword analysis revealed five research clusters that illustrate where research is progressing. The outlook indicates that a deeper understanding of microbiology and support from energy policy will drive the development of hydrogen from fermentation.
