Development of New Efficient Alloys for Hydrogen Storage
Program: VEGA
Project leader: Mgr. Oroszová Lenka, PhD.
Annotation: The project focuses on the development and research of medium and high entropy alloys for hydrogen storage. Currently, the most efficient and safest way to store H2 is its chemical bonding in the metal alloys lattices to form metal hydrides. The problem with current alloys is the too high temperature (exceeding 400 °C) at which H2 is released from their volume. The latest trend in material development in this area (defined also by the work of the project applicants) is towards microalloying of high entropy alloys with elements that can significantly reduce the desorption temperature of H2 from their volume. The amount of stored hydrogen can also be increased by plastic deformation of the matrix. Both of these approaches are the subject of this scientific project. Our main goal is to develop materials with high absorption capacity (> 2 wt.%), low desorption temperature < 140 °C and high cyclic absorption/desorption stability (> 1000 cycles with a capacity decrease of less than10%).
Duration: 1.1.2025 – 31.12.2028
