Dear Colleagues,

In the transition towards renewable energy (RE), hydrogen produced via electrolysis is a promising solution for large-scale energy storage due to a very high energy density per kg and null self-discharge once stored. In this context, hydrogen can be directly used in the industry or facilitate the coupling among sectors (e.g., FCH mobility or link between electricity and gas grids). This process is known as power-to-hydrogen. However, wide commercialization of advanced energy devices, such as water electrolysis technologies (e.g., PEM, AEM, alkaline) is closely linked to the cost, activity, and durability of the electrocatalysts.

This Special Issue will cover the most recent progress and advances in the field of non-critical raw materials (CRMs) and CRMs as electrocatalysts in the water electrolysis field.

The goal is to contribute to the road-map addressing the achievement of a wide-scale decentralized hydrogen production infrastructure with the long-term goal to reach net-zero CO₂ emissions. Significant advances in cell materials can contribute significantly to reducing the electrolyzer CAPEX and OPEX costs. Studies on end of life processes and cost and life cycle assessment of electrocatalysts (e.g., LCC and LCA) will be welcome in this Special Issue.

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. Catalysts 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 2700 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.
