Green Hydrogen Systems: Advances in Production, Storage and Efficiency Optimization

Dear Colleagues,

The Special Issue, titled “Green Hydrogen Systems: Advances in Production, Storage and Efficiency Optimization,” aims to highlight recent scientific and technological developments in hydrogen as a key energy carrier for a sustainable and low-carbon future. Hydrogen plays a critical role in decarbonizing energy systems, supporting renewable integration, and enabling clean fuel pathways across the industrial, transportation, and power sectors.

This Special Issue welcomes original research and review articles addressing innovative approaches to hydrogen generation, including electrolysis; thermochemical, biological, and reforming processes; and emerging catalyst and reactor designs. It also focuses on advanced hydrogen storage technologies such as compressed, liquefied, and solid-state systems and the development of novel materials to improve storage capacity, safety, and efficiency. In addition, this issue emphasizes process optimization, system integration, and techno-economic analysis to enhance the performance, scalability, and sustainability of hydrogen technologies in real-world applications.

Topics of interest for this Special Issue include, but are not limited to, the following:

• Green and low-carbon hydrogen production technologies;
• Electrolysis (PEM, alkaline, and SOEC) and photoelectrochemical systems;
• Hydrogen production from biomass, waste, and thermochemical cycles;
• Steam methane reforming with carbon capture (blue hydrogen);
• Catalyst design and reactor engineering for hydrogen processes;
• Hydrogen storage technologies (compressed, liquid, and solid-state LOHCs);
• Advanced storage materials (metal hydrides, MOFs, and nanomaterials);
• Hydrogen transport, distribution, and infrastructure;
• Process modeling, simulation, and optimization;
• Integration with renewable energy systems (wind, solar, and hybrid systems);
• Energy system optimization and hydrogen value chain analysis;
• Safety, lifecycle assessment, and techno-economic analysis;
• Industrial applications of hydrogen (fuel cells, ammonia production, and synthetic fuels).

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. Processes is an international peer-reviewed open access semimonthly 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 2400 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.
