Recent developments in the fabrication, characterization and implementation of MgH2-based solid-hydrogen materials in the Kuwait Institute for Scientific Research

Abstract

Hydrogen energy holds tremendous promise as a new clean energy option. It is a convenient, safe, versatile fuel source that can be easily converted to the desired form of energy without releasing harmful emissions. Hydrogen storage, which spans both hydrogen production and hydrogen applications, plays a critical role in initiating a hydrogen economy. Apart from the traditional methods used for hydrogen storage, Mg metal has been considered to be the most suitable candidate for application as a safe hydrogen storage material. However, Mg still has several technical problems that must be solved before such an attractive light metal can be considered for use in real applications. This review article aims to present and discuss the most recent research activities (2010-2018) that have been undertaken at the Kuwait Institute for Scientific Research (KISR) to develop and implement new categories of MgH2-based nanocomposites. Comparisons between different catalytic agents used to enhance MgH2 properties are presented and discussed in terms of structure, morphology, thermal stability, and kinetics.
