Solid State Hydrogen Storage in Alanates and Alanate-Based Compounds: A Review [PDF]

open access: yesMetals, 2018
The safest way to store hydrogen is in solid form, physically entrapped in molecular form in highly porous materials, or chemically bound in atomic form in hydrides.

Sorption and desorption properties of a CaH2/MgB2/CaF2 reactive hydride composite as potential hydrogen storage material [PDF]

open access: yesJournal of Solid State Chemistry, 2011
The hydrogenation behavior of 3CaH{sub 2}+4MgB{sub 2}+CaF{sub 2} composite was studied by manometric measurements, powder X-ray diffraction, differential scanning calorimetry and attenuated total reflection infrared spectroscopy. The maximum observed quantity of hydrogen loaded in the composite was 7.0 wt%.

Microstructural study of hydrogen desorption in 2NaBH4 + MgH2 reactive hydride composite

open access: yesInternational Journal of Hydrogen Energy, 2012
Abstract The desorption mechanism of as-milled 2NaBH 4  + MgH 2 was investigated by volumetric analysis, X-ray diffraction and electron microscopy. Hydrogen desorption was carried out in 0.1 bar hydrogen pressure from room temperature up to 450 °C at a heating rate of 3 °C min −1 . Complete dehydrogenation was achieved in two steps releasing 7.84 wt.

Oxidation State and Local Structure of Ti-Based Additives in the Reactive Hydride Composite 2LiBH4 + MgH2

open access: yesThe Journal of Physical Chemistry C, 2010
Nowadays, the technological utilization of reactive hydride composites (RHC) as hydrogen storage materials is limited by their reaction kinetics. However, addition of transition-metal-based additives, for instance titanium isopropoxide (Ti-iso), to the 2LiBH4+MgH2 system, results in a significant improvement of sorption kinetics.

Simultaneous desorption behavior of M borohydrides and Mg2FeH6 reactive hydride composites (M = Mg, then Li, Na, K, Ca) [PDF]

open access: yesApplied Physics Letters, 2015
Combinations of complex metal borohydrides ball milled with the transition metal complex hydride, Mg2FeH6, are analysed and compared. Initially, the Reactive Hydride Composite (RHC) of Mg2+ cation mixtures of Mg2FeH6 and γ-Mg(BH4)2 is combined in a range of molar ratios and heated to a maximum of 450 °C.

Composite materials for hazard mitigation of reactive metal hydrides [PDF]

open access: yesInternational Journal of Hydrogen Energy, 2013
Abstract In an attempt to mitigate the hazards associated with storing large quantities of reactive metal hydrides, polymer composite materials were synthesized and tested under simulated usage and accident conditions. The composites were made by polymerizing vinyl monomers using free-radical polymerization chemistry, in the presence of the metal ...
