To improve their performance, much effort has been devoted to the fundamental properties of metal amides, such as electronic structure, and the energetics of their hydrogen reactions. Though understanding the amino anion transition in the hydrogen reaction is essential for further development, the role of the amino anion in metal amides/imides for hydrogen storage is still ambiguous. Nanostructured metal amides and nitrides are incorporated into nanoporous templates, such as carbon, using liquid ammonia as a solvent/reagent.

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 . Hydrogen desorbed from these compounds contaminated by a small amount of NH3 originated from decomposition of the amides themselves, which would be a Sodium borohydride has been considered as a solid state hydrogen storage candidate. Although practical temperatures and pressures for hydrogen storage have not been achieved, in 2012 a core–shell nanostructure of sodium borohydride was used successfully to store, release and reabsorb hydrogen under moderate conditions.

The hydrogen bonds to the metal particles to form metal hydride, a stable and safe compound. With simple adjustments of the temperature, the hydrogen can be released to a fuel cell and converts back into electrical power. 2020-08-13 · The Fuel Cell Technologies Office's (FCTO's) metal hydride storage materials research focuses on improving the volumetric and gravimetric capacities, hydrogen adsorption/desorption kinetics, cycle life, and reaction thermodynamics of potential material candidates. The Hydrogen Storage Engineering How powder metal hydrides solve safety and size challenges for hydrogen storage. Global warming concerns linger and extreme weather events over the last decade have demonstrated the intensified need for a deeper commitment to proactive energy policies.
Among the known hydrogen storage materials, amide and imide-based mixtures represent the most promising class of compounds for on-board applications; however, some barriers still have to be overcome before considering this class of material mature for real applications. Apr 5, 2019 Hydrogenation of a lithium-potassium (double-cation) amide The metal hydride -ammonia (MH-NH3) hydrogen storage system was derived
