Overview
ABSTRACT
Alanates, inorganic compounds formed by an anionic complex Al-H and a metal cation, contain large quantities of hydrogen. At this time, the sodium tetra-alanate,, NaAlH4, is the most promising compound for the reversible storage of hydrogen under normal pressure and temperature conditions. It absorbs 5.6 wt. % of hydrogen with a high volumetric density (70 kgH/m3), a high compactness (kgH/m3 70) and fast hydrogenation kinetics in the presence of titanium-based dopants.
