Special Issue Information
Dear Colleagues,
Today, energy storage technology has become an important issue as energy sources such as fossil fuels and natural gas are not infinitely available, and even if they were, their combustion or end products are not environmentally friendly.
Hydrogen represents an attractive alternative as a clean, highly abundant, and non-toxic renewable fuel. Hydrogen offers high energy density by mass and proves to be an efficient energy carrier. However, its low volumetric density necessitates high pressures or low temperatures for compact storage, which presents a limit to its broader application.
Solid hydrogen storage, especially metal hydride, exhibits excellent hydrogen storage capacity, with a volumetric hydrogen storage density exceeding that of liquid hydrogen, and safety superior to a low-pressure vessel. A nanoporous Mg-based material with nanoscale pores proved to be a good material for efficient and controllable in situ hydrogen generation. However, challenges remain in terms of scaling up for large-scale practical applications. Zirconium-based materials can be used as hydrogen storage materials in fuel cells, providing a compact and efficient way to store hydrogen on one side, and absorbing impurities like oxygen and nitrogen, which can be crucial for maintaining fuel cell performance, on the other side. However, the lower hydrogen storage capacity (wt%) limits its application. Other metal hydrogen storage materials, such as LaNi5, TiFe, as well as multicomponent alloys, have shown promising hydrogen storage capabilities with fast kinetics at room temperature and need further investigation.
The Special Issue aims to compile insights into the challenges associated with the development of advanced storage methods and materials that have the potential to increase commercial applicability. We would very much appreciate the inclusion of recent findings, case studies, or data concerning the technical and economic challenges of hydrogen energy storage material adoption and overcoming the above-mentioned disadvantages.
We look forward to your contributions.

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. Metals 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 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.
