Hydrogen storage in complex metal hydrides

Complex metal hydrides such as sodium aluminohydride (NaAlH4) and sodium borohydride (NaBH4) are solid-state hydrogen-storage materials with high hydrogen capacities. They can be used in combination with fuel cells as a hydrogen source thus enabling longer operation times compared with classical metal hydrides. The most important point for a wide application of these materials is the reversibil...

Complex Hydrides for Hydrogen Storage

Complex hydrides, containing a minimum of 7.5 wt% hydrogen, are being investigated as hydrogen storage compounds for automotive use. As a new project, the work to date has largely involved refurbishment of equipment and acquisition of study materials. Initial experiments have confirmed that the instrumentation is functioning and that the data being obtained agree with that in the literature. In...

First Principles Based Simulation of Hydrogen Interactions in Complex Hydrides, excerpt from DOE Hydrogen Program 2006 Progress Report

Project Scope Our goal is to develop a multiscale approach to model desorption and adsorption of hydrogen in complex metal hydrides. In this initial stage of the project, we started by using density-functional-theory quantum chemical calculations to study the structure of complex metal hydrides and the interactions of hydrogen with the metal atoms in these hydrides. We analyzed the crystal stru...

Hydrogen Storage in light complex Hydrides – structural studies

The most important unsolved problem for the introduction of the Hydrogen Economy is efficient and safe storage of hydrogen. Alanates, compounds based on the AlH4 unit, are among the most promising metal hydrides for reversible hydrogen storage. The storage capacity is large, e.g. NaAlH4 can release 5.6 wt% hydrogen below 200 C. Work during the last years has revealed that Ti additives improve t...

Modified Borohydrides for Reversible Hydrogen Storage (2)

This paper reports the results in the effort to destabilize lithium borohydride for reversible hydrogen storage. A number of metals, metal hydrides, metal chlorides and complex hydrides were selected and evaluated as the destabilization agents for reducing dehydriding temperature and generating dehydriding-rehydriding reversibility. It is found that some additives are effective. The Raman spect...
