Anisotropic clay materials for hydrogen storage – OCCAMH2

Anisotropic clay-based materials for hydrogen storage (OCCAMH2)

Hydrogen is the carbon-free fuel par excellence because its combustion emits only water. At present, the limiting point to a massive deployment of technologies using hydrogen for energy purposes is its storage. Our aim is to propose green materials, namely textured materials based on natural objects (lamellar and tubular clays), for hydrogen storage. The OCCAMH2 project is a fundamental research project in the field of energy and materials sciences.

Research hypothesis and project objectives

The breakthrough concept to be explored is the role of the anisotropy of the porous network for hydrogen storage. The research hypothesis is that hydrogen storage will be an emergent property of the material (anisotropy of the porous network) and will not only come from the intrinsic properties of its elementary bricks. The first objective of the project is to realize materials based on clay nanotubes for a wide range of anisotropy. The second objective is to precisely characterize and model the anisotropy of the porous network. The third objective of the project is to identify and analyze the impact of the anisotropy of the porous network on hydrogen storage.

The project implements a complete set of experimental methods (X-ray and neutron scattering, adsorption isotherm measurements) coupled with modeling.

Our aim is to propose green materials, namely textured materials based on natural objects (lamellar and tubular clays), for hydrogen storage. The OCCAMH2 project is a fundamental research project in the field of energy and materials sciences. It implements a comprehensive set of experimental methods coupled with modelling. Four teams with complementary skills, in physics, chemistry and geosciences, are gathered together. The breaking concept to explore is the role of the anisotropy of the pore network for hydrogen storage. The research hypothesis underlying the project is that the storage of hydrogen will be part of an emerging property of the material (pore network anisotropy) and will not come only from the intrinsic properties of its elementary bricks.
