Development of Novel Hydrogen Storage and Release Metal-Based Alloys and Composites

Dear Colleagues,

As a result of the drive to mitigate climate change and ensure energy security, technologies related to hydrogen generation, transportation, storage, and use are being keenly pursued in many different parts of the world. However, hydrogen storage has not seen remarkable advancement in the last decade compared to other technologies. Hydrogen storage materials based on metal and alloys have been the subject of research for many years. There is extensive literature on Mg-based alloys, different types of transition metal and rare-earth intermetallic compounds, and high-entropy alloys, which have shown exciting hydrogen storage properties. By now, however, it should be clear that it is unlikely that a unique material will be found to satisfy all the different requirements imposed by the multiple applications envisioned for hydrogen in the coming years. Consequently, continuing efforts to develop novel metal-based hydrogen-storage materials and bring them closer to practical applications are of interest to the scientific and engineering communities.

This Special Issue aims to highlight current research works which provide new insights into the synthesis, characterization, and properties of metallic alloys and metal-matrix composites under study and development for hydrogen storage applications. Contributions exploring the relationships between microstructure and storage capacity, hydrogenation and dehydrogenation kinetics, and cyclic and environmental stability are particularly welcome. In addition, computational methods for predicting phases in multicomponent systems, reaction kinetics, and alloy design are also of great importance for the progress in this research topic. Finally, studies focused on the scale-up of research experiences into pilot-plant developments will be highly useful for the overall assessment of state-of-the-art hydrogen storage. Therefore, we are pleased to invite submissions on recent research on hydrogen storage in metal-based alloys and composites, as well as critical reviews on the subject, which may help to guide future efforts on this significant technological challenge.

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.
