Novelty in Hydrogen Storage Materials for Energy Application

Dear Colleagues,

Hydrogen is an alternative source of energy due to its various advantages, such as higher energy density (142 MJ/Kg), non–polluting characteristics and renewable nature. Nowadays, hydrogen can be stored in three possible ways, including liquid hydrogen storage, compressed hydrogen gas and adsorbed hydrogen in a solid porous material. As compared to gaseous and liquid hydrogen storage technologies, solid materials that are porous and hydrides can securely store hydrogen at a higher density. However, various challenging issues are associated with the storage of hydrogen in a safe, efficient and economical way, particularly for mobile application. These solid materials have greater storage capacity both in terms of volume and weight percent but kinetics of hydrogen storage and release require to be very fast, and refills of the hydrogen storage materials are also an issue. Recently, different kinds of materials have been studied, where the following properties are required for hydrogen storage:

1. High gravimetric and volumetric density of hydrogen;
2. The reversible hydrogen adsorption–desorption under conditions of moderate temperature and pressure, which have suitable thermodynamic features;
3. Kinetic studies;
4. Easy to handle;
5. Abundant resources and affordable.

This Special Issue, entitled "Novelty in Hydrogen Energy Storage Materials", will concentrate on the most recent developments regarding porous and hydrides materials for hydrogen storage. This Special Issue will accept original research and reviews articles in subject areas, including the fabrication of novel porous materials and hydrides for hydrogen storage. We welcome submissions that include, but are not limited to, the following topics: porous materials (carbon, MOFs, CNTs, graphene, zeolite, etc.); hydrides (NaAlH₄, MgH₂, LiBH₄, TiFeH₂ and Mg(BH₄)₂) for hydrogen storage; hydrogen adsorption–desorption characteristics; kinetic studies; hydrogen production; and materials-based prototype.

We look forward to receiving 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. 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.
