Methodologies & Experimentation for Materials and Structures in Complex Environments
For our M2SC team, focus is on the study and development of materials and structures subjected to complex loads in aggressive environments. An example of this is the stress that an oil pipeline, reinforced by filament winding, undergoes when crossing an arid region. This is also, and above all, the case of hydrogen interactions in all materials used for storage in this energy carrier.
The team’s goal is to develop an approach that is material, mechanical and even physicochemical, to provide specific expertise in response to new requirements for materials and structures in complex environments.
Goals and Research Areas
The M2SC team’s main subject area is the use of hydrogen for the storage of energy produced from diverse renewable sources. Technologically, the team is particularly interested in improving the characteristics of metal hydrides without rare earth metals and functioning at relatively low pressures and temperatures.
› Optimization of storage capacities of hydrides, simplification of the activation step and increase in the absorption-desorption kinetics which are interdependent.
› Comprehension of the nucleation phenomenon during hydrogen absorption, which is particularly important in hydrides based on Ferro-Titanium alloys.
› Furthering knowledge of behavior of polymeric materials in a hydrogen atmosphere under extreme conditions of temperature (-70°C to 120°C) and pressure (100 to 1200 bars).
With its experience in composite materials and structures, the M2SC team is highly skilled in the design and sizing of high-pressure hydrogen storage tanks. It has also acquired the fundamental knowledge necessary to understand and measure hydrogen permeation through polymeric or metallic materials. The team continues to study hydrogen-matter interaction with metallic hydrides used for reversible hydrogen storage.
In cooperation with the regional company MaHyTec, the M2SC team works towards improving metallic hydride characteristics through identification of the surface or micro-structural phenomena involved in hydration-dehydration reactions. On the national level, the team takes part in FUI style partnership contracts with tech companies for the use of hydrogen and the storage of renewable energies.
Implementing our work
For the further development of the hydrogen sector, the M2SC team participates in both regional and international organizations. Regionally, the team is supported by local and regional authorities and enjoys privileged partnerships with the company MaHyTec. It also participates actively in the ISTHY project (institute for hydrogen storage) with Research and Training components to help organize the emerging hydrogen storage industry.
