Scaled-up production of a promising Mg-based hydride for hydrogen storage

Hydrogen sorption kinetics of magnesium hydride enhanced by the addition of Zr 8 Ni 21 alloy

“…9, resulting to be H = −73.9 ± 0.7 and −77.7 ± 0.8 kJ/mol and S = 134.2 ± 1.2 and 141.8 ± 1.5 kJ/mol for absorption and desorption, respectively, in agreement with previous data (see, e.g., Ref. [16]), proving once more that the use of an additive to MgH 2 does not change the thermodynamic properties of hydrogen a/d process.…”

The catalytic effect of titanium oxide based additives on the dehydrogenation and hydrogenation of milled MgH2

“…These plots are shown in Figs. [8][9]. Linearity coefficients are listed in the figure captions to confirm the best fitting model for each set of data.…”

“…Studies have shown that the kinetics can be improved through milling [3], mechanical alloying [4,5], and addition of various additives [6], including metals [7][8][9], metal oxides [4,[10][11][12][13], transition metal fluorides [13][14][15][16], graphite [17] and carbon nanotubes [17,18] and combinations of the above such as carbon nanotubes (CNT) and metal fluorides [19], CNT and transition metals [6]. Previous studies reported in the literature indicate that metal oxides can * Corresponding author.…”

Design, Construction, and Operation of a High‐Energy Mill for Handling Magnesium Powder

“…Metal hydrides such as MgH 2 or some complexes as NaAlH 4 and LiAlH 4 are attractive for this use, store 7.6, 7.3, and 10.1% by weight and hydrogen, respectively, have a low overall weight [11,12]. Hydrides of pure metals and alloys are an efficient and safe with good hydrogen storage capacity per unit mass storage medium, but generally have slow desorption kinetics and rupture temperatures near 300 ∘ C 2 Mathematical Problems in Engineering equilibrium with little stability before repeated cycles of absorption and desorption [13,14].…”
