Special Issue Information
Dear Colleagues,
“Green hydrogen” is increasingly recognized as a promising solution for decarbonizing a wide range of industrial sectors, including transportation, energy storage, metal production, and chemical production. The development of advanced water electrolysis technologies is essential to producing cost-effective green hydrogen at scale. As such, the design and fabrication of efficient, durable, and safe water electrolyzers has become a highly active area of research, attracting significant attention from experts across chemistry, physics, materials science, and engineering.
This Special Issue aims to highlight recent advancements in catalysts and electrodes for water electrolysis technologies. We welcome a broad range of contributions spanning theory, synthesis, characterization, application, and modelling.
Topics of interest include the following:
- Novel catalytic materials for the oxygen and hydrogen evolution reactions, especially low-Ir/Pt or Ir/Pt-free systems;
- Advanced catalyst supports for enhanced durability and performance;
- AI-assisted or model-based catalyst screening methods (e.g., density functional theory, molecular dynamics);
- In-depth characterization and analysis of catalyst degradation mechanisms;
- Advanced manufacturing processes for ionomer-containing or ionomer-free electrodes;
- Cost-effective, high-performance, and durable water electrolyzer design and fabrication strategies;
- Accelerated stress testing protocols.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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. Energies 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 2600 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.
