Since the 1970s, hydrogen has been considered as a possible energy carrier for storage of renewable energy. The main focus on addressing ultimate challenge: developing an environmentally friendly successor gasoline. This very ambitious goal not yet fully reached, discussed in this review, but range new lightweight hydrogen-containing materials discovered with fascinating properties. State-of-the-art and future perspectives solids will be discussed, metal borohydrides, which reveal...

In a future system, production, storage of key technology. Hydrogen will be even more used industrial production processes reduction agent or synthetic hydrocarbons, especially chemical industry refineries. Under certain conditions material based systems compression offer advantages...
In context of investigations doped sodium alanate as a hydrogen storage material, an investigation combining TEM-EDX study and XAFS measurements has been carried out on alanate, using titanium tetrabutylate (Ti(OBun)4), colloidal nanoparticles (Ti*) or TiCl3 doping agents. It was found that the dehydrogenated wet-chemically Ti(OBun)4 NaAlH4 consists crystalline Al amorphous NaH phase. The striking result EDX analyses is in each case Ti-dopant to be present only On other hand, with Ti*...
The goal of the EU Horizon 2020 RISE project 778307 "Hydrogen fuelled utility vehicles and their support systems utilising metal hydrides" (HYDRIDE4MOBILITY), is in addressing critical issues towards a commercial implementation hydrogen powered forklifts using hydride (MH) based storage PEM fuel cells, together with for refuelling at industrial customers facilities. For these applications, high specific weight metallic hydrides has an added value, as it allows counterbalancing vehicle no...

Hydrides of the AB2 Laves type alloys (A=Zr, Ti; B = transition metal – Fe, Co, Ni, Mn, Cr, V) have been extensively studied as materials for storage gaseous hydrogen. They contain up to 4 H atoms/formula unit AB2, thus achieving reversible capacities in range between 1.5 and 2.0 wt% offering high rates hydrogen charge discharge, making them suitable designing efficient stores operating at ambient conditions. In present study, we performed an experimental study modeling thermodynamics...
In coarse-grained MgH2, the diffusive motion of hydrogen remains too slow (<105 hops s−1) to narrow H NMR line up 400 °C. Slow-motion dipolar relaxation time T1D measurements reveal motion, with hopping rate ωH from 0.1 430 s−1over range 260 °C, first direct measurement in MgH2.
