Special Issue Information
Dear Colleagues,
Hydrogen is recognized as a clean energy source and a key chemical raw material. Currently, more than 90% of hydrogen is produced from fossil fuels via reforming, which inevitably generates large amounts of CO2 emissions. Therefore, green hydrogen production powered by renewable energy sources (e.g., solar, wind, hydro) is highly desired for realizing a sustainable, carbon-neutral energy future. In addition, the storage and utilization of the green hydrogen produced are also of utmost importance to achieve a circular hydrogen economy and net-zero carbon emissions.
There are multiple ways to realize green hydrogen production. Water electrolysis powered by renewable energy is considered the best, including alkaline water electrolysis, anion exchange membrane water electrolysis, proton exchange membrane water electrolysis, solid oxide electrolysis, and proton conducting ceramic electrolysis. Recent years have witnessed enormous efforts, in particular, from emerging young investigators, in developing insightful understanding, new materials, and/or advanced technologies for increasing the performance, durability, and cost-effectiveness of these water-splitting processes. Endeavors such as desalination of water, power generation and storage through renewable energy, etc., have also been undertaken to contribute to cost reductions in green hydrogen production. There is also considerable interest in exploring materials and technologies for hydrogen storage (e.g., metal hydrides, liquid organic hydrogen carriers) and utilization (e.g., fuel cells, ammonia production, petroleum refining).
This Special Issue aims to collect papers dealing with green hydrogen, spanning its production, storage, and utilization, with a special focus on young investigators’ point of view. All efforts, experimental or theoretical, are encouraged. In addition, a particular focus on new achievements in the field will be appreciated.

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. Molecules 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 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.
