“…In solid hydrogen storage compounds, sonication has been used in different contexts. Hydrides that need very high temperatures to be synthesized such as zirconium hydride (ZrH 2 ) are easily formed by sonication of mixtures containing zirconium chloride (ZrCl 4 ), sodium bicarbonate (NaHCO 3 ) and distilled water . Sonication also was used to synthesise borohydrides derivatives .…”

In the last decades, a broad family of hydrides have attracted attention as prospective hydrogen storage materials of very high gravimetric and volumetric capacity, fast H 2 -sorption kinetics, environmental friendliness and economical affordability. However, constraints due to their high activation energies of the different H 2 -sorption steps and the Gibbs energy of their reaction with H 2 has led to the need of high thermal energy to drive H 2 uptake and release. High heat leads to significant degradation effects (recrystallization, phase segregation, nanoparticles agglomeration…) of the hydrides. In this context, this short review aims to summarize alternative non-thermal methods and non-straightforward thermally driven methods to overcome the previous constraints. The phenomenology lying behind these methods, i. e. tribological activation, sonication, and electromagnetic radiation, and the effect of these processes on hydrogen sorption properties of hydrides are described. These non-usual approaches could boost the capability of the next generation of solid-hydride materials for hydrogen conversion in energy sector, in mobile devices and as hydrogen reservoirs.[a] J.
