Biohydrogen Production from Effluents Using Anaerobic Bacteria: A Bibliometric Review

Resumo

This study investigates biohydrogen production from effluents using anaerobic bacteria through a bibliometric review supported by VOSviewer software. The potential of biohydrogen as a sustainable energy alternative is highlighted, as evidenced by growing academic interest. The analysis, focused on documents published between 2019 and 2024, reveals 141 publications that show trends, technical and economic challenges, and opportunities for process optimization and technological integration. Continued research is recommended to overcome barriers and promote biohydrogen's viability, also considering its large-scale production's environmental and social impacts.
