H2MobilHydride

The joint initiative unites scientists from the University of West Bohemia in Pilsen (UWB), the Slovak Academy of Sciences (SAS) in Kosice, the company SVÚM and the Chair of Forming and Joining (UFF). Under the experienced leadership of Prof. Karel Saksl (SAS) and Prof. Ludmila Kucerova, extensive expertise in the field of metal hydride storage is contributed. The project is part of the EU-funded M-Era.Net project "H2MobilHydride" and aims to improve the capacity as well as the kinetic properties of hydrogen uptake and release by novel compositions of high entropy alloys. Special attention is given to the investigation of the influence of the processing of these alloys on the storage capacity. 

Metal hydrides have recently emerged as promising materials for local hydrogen storage. The innovation goals of this project are to provide a novel metal hydride composite offering hydrogenation capacity close to Mg alloys, faster kinetics, higher dehydrogenation capacity, and limited material degradation per cycle. The material will be based on the concept of high entropy alloy with the addition of catalysts and will be produced not only in the conventional powder form, but also as thin sheets and bulk materials. A hydrogen storage capacity of (H/M)>1.8, a mass fraction of stored hydrogen >2.5, a volume fraction of stored hydrogen >0.15kg/l and an absorption rate to complete saturation < 2min are aimed. The project will improve the fundamental understanding of the mechanisms governing the hydrogenation and high-temperature behavior of HEA-based composites and also provide a functional model of a new composite material for hydrogen storage, followed by a technology for its fabrication.

This project is co-financed from the state budget by the Technology Agency of the Czech Republic under the M-ERA.NET Joint Call 2022 Programme within the ERA-NET Cofund.
