Description: Research on hydrogen storage has been conducted for decades and many methods and materials have been developed for application to transportation (fuel cells). Currently, several classes of materials are being pursed as possible candidates for hydrogen storage including simple and complex metal hydrides (both bulk and nanoscale), and carbon nanomaterials. Issues such as the chemical state, structure and role of metal catalysts and the detailed structural changes during hydrogen binding and removal are not well understood. In order to obtain materials that can be reversibly cycled at low temperature it is absolutely essential to understand these properties and to determine the mechanisms involved in hydrogen binding. The spectroscopic and structural tools available at the synchrotron radiation sources are uniquely suited to address the fundamental issues required to optimize these materials.
