Special Issue Information

Dear Colleagues,

Solid-state hydrogen storage materials (SSHM) have fascinated researchers all over the world for the last 70 years. Despite the fact that very ambitious DOE (Department of Energy, USA) expectations for mobile hydrogen containers are being constantly lowered, for most of the experts in the field, it is obvious that without some new breakthrough it is very unlikely that currently used solid-state materials will solve the hydrogen storage problem for transportation.

This does not mean, however, that the progress made in this field within those years brought manhood to nothing. In fact, this huge driving force caused great progress within the chemistry of hydrogen-containing materials and materials engineering. Binary hydrides considered as good candidates for storing hydrogen in solid state are now only a very small fraction of the investigated compounds. The group of prospective materials has been developed a lot and now includes, for example, intermetallic-based hydrides, complex hydrides, alanates, borohydrides, amides, and others. The progress involved not only discoveries of new materials but also methods for forcing many of them to be reversible in relatively mild temperature and pressure conditions.

Together with the great number of studied compounds, new experimental techniques were developed and improved to allow successful synthesis of materials, composites, and their effective modification with catalytic additives. The progress also involved characterisation techniques, which became more precise, faster, and more flexible.  

Materials considered years ago as a source of hydrogen for mobile applications recently became objects of study for less demanding stationary energy sources and heat storage materials for solar thermal applications, i.e., for solar thermal energy storage.

Because of the above-mentioned reasons, the current Special Issue is supposed to cover all aspects connected with the synthesis, characterisation, and application of the hydrides-based materials including, especially, but not only, new hydrides-based materials, new technologies for the synthesis of hydrogen storage materials, new characterisation tools and modifications of current techniques, new catalysts for the decomposition and synthesis of hydrides-based materials, practical examples of the application of solid-state hydrogen storage materials, and problems related to measurement techniques and data accuracy in this field.

It is our pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are expected to be submitted.

Enhanced Stability of Li-RHC Embedded in an Adaptive TPX™ Polymer Scaffold
Materials 2020, 13(4), 991; https://doi.org/10.3390/ma13040991 - 22 Feb 2020

In this work, the possibility of creating a polymer-based adaptive scaffold for improving the hydrogen storage properties of the system 2LiH+MgB2+7.5(3TiCl3·AlCl3) was studied. Because of its chemical stability toward the hydrogen storage material, poly(4-methyl-1-pentene) or in-short TPXTM was chosen as the candidate for the scaffolding structure. The composite system was obtained after ball milling of 2LiH+MgB2+7.5(3TiCl3·AlCl3) and a solution of TPXTM in cyclohexane. The investigations carried out over the span of ten hydrogenation/de-hydrogenation cycles indicate that the material containing TPXTM possesses a higher degree of hydrogen storage stability.
