Functional anion concept: effect of fluorine anion on hydrogen storage of sodium alanate.
Doping NaAlH(4) with Ti-catalyst has produced a promising hydrogen storage system that can be reversibly operated at moderate temperature conditions. Of the various dopant precursors, TiCl(3) was well recognized due to its pronounced catalytic effect on the reversible dehydrogenation processes of sodium aluminium hydrides. Quite recently we experimentally found that TiF(3) was even better than ...
متن کاملThe Development of a Fullerene Based Hydrogen Storage System
This is the final report of a three-year, Laboratory Directed Research and Development (LDRD) project at Los Alamos National Laboratory (LANL). The project objective was to evaluate hydrogen uptake by fullerene substrates and to probe the potential of the hydrogedfullerene system for hydrogen fuel storage. As part of this project, we have completed and tested a fully automated, computer control...

SRT Group, Inc. (SRT), a leader in innovative energy processes involving halogens, has developed and patented an innovative electrical energy storage and hydrogen production system. The SRT system stores off-peak electricity and produces hydrogen via a novel natural gas/steam thermo-electrochemical process. The following economic analysis indicates that the system can provide on-peak electrical...
متن کاملThe effect of alkaline earth metals (Magnesium and Calcium) on Hydrogen storage efficiency of alanate nanopowders
Different Aluminum: alkaline earth metal atomic weight ratios effects on structure transformations in alanates nanopowders were studied. Changes in crystal structures from alane to alanates by increasing alkaline earth metals dopants in the mixture with slight changes in crystal structures from rhombohedral centered – trigonal (alane) to trigonal (magnesium alanate), and monoclinic (calcium ala...
متن کاملTowards understanding a mechanism for reversible hydrogen storage: theoretical study of transition metal catalysed dehydrogenation of sodium alanate.
On the basis of density functional theory and coupled-cluster CCSD(T) calculations we propose a mechanism of the dehydrogenation of transition metal doped sodium alanate. Insertion of two early 3d-transition metals, scandium and titanium, both of which are promising catalysts for reversible hydrogen storage in light metal hydrides, is compared. The mechanism is deduced from studies on the decom...
