THERMOUSSEL

Several use cases can be envisaged. For example, waste heat can be captured in one location and returned to another nearby location, providing a means of saving energy and decarbonisation. Or energy can be collected, for example photovoltaic energy, to be returned later in the form of thermal energy, with the possibility of shifting the timing of energy collection and consumption.
The most suitable use cases will be evaluated during the project.

Today, there is considerable interest in developing energy storage systems that combine low cost, high efficiency and a reduced carbon footprint.
Thermochemical storage can be an advantageous solution because it takes advantage of salts that crystallise with water. The hydration of salt releases heat, while its dehydration requires energy.
While salt hydrates lose efficiency over several cycles, TherMousSel technology enables reversibility thanks to a porous medium in which the salt is absorbed and air circulation within this network. Reversibility has been demonstrated over several cycles without any loss of efficiency.

Thermochemical storage provides heat while consuming little energy to power the system (a simple circulation of dry air, for example) and allows for a phase shift in energy consumption (thermal).
It is a low-tech technology with little need for materials, as it uses off-the-shelf products: commercially available foams and salts, which are common chemicals.
