Indirect hydrogen storage

This chapter is focused on the potential of indirect hydrogen storage by use of ammonia stored in metal ammines. Section 19.2 describes ammonia as a potential hydrogen storage medium, ammonia production and infrastructure, safety concerns and the energy costs involved in indirect storage. Section... 

The important properties of the metal ammines when used as materials for indirect hydrogen storage can be understood and explained at the atomic scale. In this section, an atomic scale model of the sample system Mg(NH3)6Cl2 based on density functional theory (DFT) calculations shows how atomic structures, energies and dynamics can be connected to macro-scale properties such as shape, uptake and decomposition rates, porosity and reaction enthalpies. The model is based on experimentally observed structures (Olovsson, 1965 Partin and O Keeffe, 1991 Leineweber et al, 1999, 2000 Hummelshpj et al, 2006) and it is expected to be applicable to other metal ammines. A detailed understanding of the systems at the atomic scale is a prerequisite for the design of new and better materials. 

The use of metal ammines as indirect hydrogen storage materials is obviously entirely dependent on the process of efficiently converting ammonia to...
