Special Issue Information
Dear Colleagues,
Although the utilization of renewable energy sources has been developing rapidly in recent years, their fraction of the overall energy economy is still small. Hydrogen, as the lightest element of all, appears to be a suitable energy storage media because of its exceptional chemical energy per unit mass (142 MJkg-1) and environmental friendliness. The stored energy of hydrogen can easily be transformed to electricity in a fuel cell with a by-product of water, resulting in a 100% clean emission. Hydrogen economy appears to be one of the main hopes for solving both renewable energy needs and environmental problems. However, the efficient storage of hydrogen is still a technological challenge in the way of its wide-range applications.
Among the different solid-state hydrogen storage systems, complex and conventional metal hydrides have drawn significant attention because of their remarkable gravimetric and volumetric capacities. The kinetics and thermodynamic destabilization of these materials can be improved either by nanocrystallization and/or by different additives. Nanocrystallization based on severe plastic deformation can be processed via high energy ball milling (HEBM), equal channel angular pressing (ECAP), and cold rolling (CR). Adding catalysts, like transition metals, their oxides, and carbon-based materials, have a substantial impact on the effectiveness of hydrogen storage.
This Special Issue would like to encourage the submission of original contributions regarding recent developments on materials synthesis for efficient hydrogen storage by processing techniques based on severe plastic deformation.

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.
