Advances in Hydrogen Production: Toward a Sustainable Energy Future

Dear Colleagues,

Hydrogen is increasingly recognized as a cornerstone of future sustainable energy systems. Among the diverse hydrogen production methods, biohydrogen generated through fermentative processes offers a renewable and environmentally friendly alternative, particularly when utilizing organic wastes and biomass feedstocks. This Special Issue of Fermentation focuses on the latest developments in biological hydrogen production, with a particular emphasis on fermentation-based pathways, microbial biotechnology, and bioprocess engineering.

We invite submissions of original research papers, reviews, and short communications that explore innovative technologies and fundamental insights into the following:

• Dark fermentation and photofermentation for hydrogen production;
• Microbial consortia and metabolic pathways involved in fermentative hydrogen generation;
• Genetic and metabolic engineering that can enhance hydrogen yields;
• Bioreactor development, process intensification, and optimization;
• Use of industrial waste, lignocellulosic biomass, and algal feedstocks;
• Integration of hydrogen fermentation with wastewater treatment or biorefinery concepts;
• Omics tools (genomics, transcriptomics, proteomics, metabolomics) for microbial analysis;
• Life cycle assessment (LCA), techno-economic analysis (TEA), and system modeling of fermentative hydrogen systems.

This Special Issue aims to showcase recent breakthroughs in biohydrogen fermentation and promote interdisciplinary dialogue across microbiology, biochemical engineering, and sustainability science. By highlighting fermentative strategies, we seek to contribute to the development of scalable eco-friendly hydrogen technologies aligned with global decarbonization goals.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Fermentation is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
