Thermochemical Heat Storage via Water Sorption
M. Zbair, P. Dutournié
This research is focused on thermal energy storage, with particular emphasis on thermochemical heat storage systems based on water sorption. The aim is to develop innovative materials and processes to enhance the efficiency of thermal energy storage and release, thereby addressing key challenges in the energy transition.
The scientific work is structured around three main research areas :
1. Synthesis and Preparation of Active Materials : Development of high-capacity sorption materials, including biochars and solid composites incorporating hydrated salts (e.g., MgSO₄) or clay-based hybrid materials.
2. Advanced Characterization : Investigation of the textural, structural, and thermodynamic properties of the materials to assess their storage capacity and adsorption/desorption kinetics.
3. Modeling and Numerical Simulation : Development of thermodynamic and kinetic models to predict material performance and optimize their integration into thermochemical storage systems.
By combining experimental work, material characterization, and modeling, the research has led to the development of innovative materials with tailored properties, while also deepening the understanding of the fundamental mechanisms underlying thermochemical heat storage.
This work paves the way for the design of sustainable thermal solutions that incorporate environmentally friendly materials and deliver high energy efficiency, particularly for applications in buildings and industrial processes.
