Abstract

Hydrogen as an energy carrier has been proposed as an efficient alternative to the current energy infrastructure due to its cleanliness, unlimited supply and higher energy content per unit mass. The solid-state hydrogen storage offers a potential and safe solution compared to compressed gas as it requires no essential pressure. The search for a material having suitable properties with high gravimetric and volumetric capacities is a crucial material challenge for moving towards an energy economy based on hydrogen. Properties of H₂ storing materials are required to be lightweight, low cost, excellent kinetics of adsorption and desorption, and recyclability. Nitrogen-containing systems have emerged as promising materials for hydrogen storage. The discovery of the interaction between nitrides and hydrogen more than a decade before, opened up a new class of metal-N-H systems. Since the preliminary studies on lithium amide, several double-cation complex amide systems have been developed. The research field of these ...
