Missions

This postdoctoral project proposes to develop high-entropy multi-elemental alloys as new solids for solid-state hydrogen storage. These alloys have recently shown very interesting performances in this field thanks to their very high chemical versatility. Nevertheless, the compositional space is very large, making it difficult to find clear composition-structure-properties correlations. In this context, we are looking for a 30-month postdoctoral researcher to carry out a study on hydrogen sorption properties in high-entropy alloys and their composition-structure-properties correlations in collaboration with project partners.

Activities

- synthesis of high-entropy alloys
- physicochemical characterization: structure, microstructure, composition
- evaluation of hydrogen storage performance
- participation in experiments at large-scale instruments

Skills

- knowledge in materials science, with particular emphasis on high-entropy alloys and solid-state hydrogen storage
- in-depth knowledge of X-ray diffraction and large-scale instruments (synchrotron)
- rigorous organization of work, teamwork, communication, report writing

Work Context

This post-doctoral project is based on a partnership between several European laboratories, East-Paris Insttitue of Chemistry and Materials (ICMPE in Thiais), Institute of Energy Technology (Norway), University of Warsaw (Poland), University of Torino (Italy) and an SME (Norway). The successful candidate will be involved in several parts of the project: materials synthesis, physicochemical characterization and hydrogen storage performance evaluation. The successful candidate will be based at ICMPE.

The position is located in a sector under the protection of scientific and technical potential (PPST), and therefore requires, in accordance with the regulations, that your arrival is authorized by the competent authority of the MESR.

Light Weight High Entropy Alloys for Safe and Sustainable Energy Storage
The utilization of light-weight materials for hydrogen storage are imperative in the green transition and to ensure safety, energy-efficiency, cost-effectiveness, and suitability in storing energy from intermittent renewable sources like wind and solar. HESSENSE aims to produce light-weight High Entropy Alloys (HEAs) that will operate as hydrogen-storage materials at near-ambient conditions with reversible gravimetric capacity above 2.5 wt.%. The feasibility of the concept will ultimately be demonstrated by the construction of a H2-storage prototype tank, with materials produced by HESSENSE. The aimed performance of the HEAs from HESSENSE will make then attractive for stationary energy storage and the heavy-duty transport sector. HESSENSE thus address EU's commitment to reach carbon neutrality by 2050 by facilitating the introduction of hydrogen in several key areas and hard-to-abate sectors such as maritime sector, heavy-duty transport, and their related infrastructure.
