Here, we review the interaction between light metal borohydrides and amides for storing hydrogen, with a special emphasis on the synthetic strategies and structural, physical, and chemical properties, which reveal a correlation between the composition, structure, and dehydrogenation properties and also provide general principles to the design of new combined systems with tailored functionality.

This leads to unexpected improvements in metal amide nanoconfined hydrogen storage materials. Typical uses for SOLID-H include hydrogen supplies for gas chromatographs and fuel storage for hydrogen engines or fuel cells. Metal hydrides are the most compact way to store hydrogen (more dense than liquid hydrogen). The internal volume of the CL-400A is less than 0.7 liters. 400 liters of hydrogen capacity is more than 500 times the size of 2020-06-15 · Implementing an energy cycle that uses hydrogen requires a variety of storage and distribution technologies.

The reaction of MgH2 with LiNH2 in 1:1 ratio produces 8.1 wt% of hydrogen with the dehydrogenated product being LiMgN. This binary nitride LiMgN can be hydrogenated under 2000 psi hydrogen pressure and 160°C with TiCl3 as catalyst. A reversible 8 wt% H 2 storage capacity has been demonstrated under the conditions used in this study.

Alkali and alkaline-earth metal aluminum amides M [Al (NH 2) 4] x desorb ammonia during thermal decomposition and have recently been studied as possible hydrogen storage system by making composites with metal hydrides.

Metal amides hydrogen storage

The molecular hydrogen is initially adsorbed to the metal surface in metal hydride storage systems, then elemental (H) introduced into a metal lattice by heat output and released with the heat input.

JPL has been working to: (1) validate initial storage properties (target: >6 wt% reversible hydrogen capacity) of light element metal hydrides including LiH destabilized with Si or Ge, borohydrides, AlH 3 phases, LiBH 4 /MgH 2 mixtures, amides containing Li and Mg, and other hydrides as metal amides. Metal amides react with metal hydrides to desorb hydrogen and these reactions have been paid attention as new hydrogen storage systems since Chen et al.’s report [1].
