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...
متن کاملComplex 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...
متن کاملComplex Metal Hydrides for Hydrogen, Thermal and Electrochemical Energy Storage
Hydrogen has a very diverse chemistry and reacts with most other elements to form compounds, which have fascinating structures, compositions and properties. Complex metal hydrides are a rapidly expanding class of materials, approaching multi-functionality, in particular within the energy storage field. This review illustrates that complex metal hydrides may store hydrogen in the solid state, ac...
متن کاملDevelopment of Hydrogen Storage Tank Systems Based on Complex Metal Hydrides
This review describes recent research in the development of tank systems based on complex metal hydrides for thermolysis and hydrolysis. Commercial applications using complex metal hydrides are limited, especially for thermolysis-based systems where so far only demonstration projects have been performed. Hydrolysis-based systems find their way in space, naval, military and defense applications ...
متن کاملHydrogen-Mediated Metal Transport in Complex Metal Hydrides
Since this discovery, a number of studies have looked at improving the catalytic effects and understanding the role of additives in H2 cycling. However, the mechanism by which NaAlH4 is activated in the presence of a small amount of a transition metal is still not well understood. One of the principle questions is “How do the Al atoms migrate the long distances required during the hydrogenation...
