Beyond hydrogen storage – Metal hydrides as multifunctional materials for energy storage and conversion

Metal hydrides are of special interest for a diverse range of applications e.g. electrochemical, hydrogen, and thermal energy storage materials. The goal is to provide energy storage solutions for the intermittent renewable but sustainable energy production pathway for future generations.


The urgent need for energy storage materials for a sustainable and carbon-free society is the main stimulant for the new dawn in the development of metal hydrides in batteries, hydrogen storage materials and thermal energy storage. One application is batteries based on metal hydrides with alternative cations including Na+ and Mg2+, which are considered as cheaper, and more abundant, while potentially higher energy density compared to Li-ion batteries are achievable. Another application is to address the intermittent supply from renewable energy sources with a hydrogen-fuel cell system to provide an uninterrupted sustainable supply of energy for stationary systems and benign zero-emission vehicles, with clean water as the only reaction by-product. Renewable energy combined with efficient ways of energy storage will be a key enabler to future technologies. Metal hydrides clearly offer an attractive and versatile platform of materials, which encompass a broad array of structures and combine interesting and tuneable properties useful for a breadth of energy applications spanning from solid-state hydrogen storage, to solid-state ion conductors for batteries or fuel cells and thermal energy storage. The proposed symposium aspires to bring together ambitious young and established scientists from around the world to not only present the latest advances of the intense worldwide research but also exchange ideas as well as identify major challenges and hot-topics for future developments towards efficient solutions for energy applications.

Hydride materials display a broad range of chemical, structural and physical features. This diversity in turn yields an unrivalled breadth and scope of possible applications, particularly with the advent of nano-technological development. As such, the talks given by enthusiastic-young and world-leading researchers in this symposium are bound to captivate a wide audience.
