ECOSTORE recognizes the fact that hydrogen and battery technologies share a symbiotic relationship and are therefore mutually beneficial rather than competing technologies. Thus the ECOSTORE approach - to our knowledge for the first time in a European project - points toward joint and coordinated development of the two technologies. In order to train experts in metal hydride based materials for energy storage - chemical, as hydrogen, and electrochemical, in batteries – ECOSTORE integrates their training and research by bringing together world class groups in both fields into one joint project.
Borohydride- and nitride based materials exhibit very high hydrogen storage capacities up to 18 wt%1,2, and they – as recently found – also show excellent properties as novel solid room temperature ion conductors 3 or negative electrode materials with improved capacity4, thus allowing for very high energy storage densities. For commercial use a prerequisite is the cost efficient large scale production from abundant and relatively cheap raw materials combined with scale-up-ability, and to demonstrate the techno-economical readiness on the prototype scale. The objectives of ECOSTORE are therefore to obtain a fundamental understanding of metal hydride based energy storage materials, and to develop them towards industrial implementation, achieving high technical performance as well as cost effectiveness. Strong synergies in the fields of structural characterisation, theoretical modelling and processing of materials will form the basis for the joint development of novel metal hydrides for both, chemical and electrochemical energy storage.
The above mentioned targets will be tackled in a comprehensive range of research projects, pursued by 12 early stage researchers (ESR) and 3 experienced researchers (ER) in 10 work packages (WP).
