The study focuses on the experimentation of a significant scale prototype using zeolite 13X/H 2 O as the reactive pair, and on the development of a 1D mathematical model used to predict both the charging (desorption) and the discharging (adsorption) processes occurring inside the storage unit. The experimental campaigns and the numerical results lead to some promising conclusions on the thermal performances of such a storage unit. With 40 kg of zeolite, a temperature lift of 38 °C on average at the outlet of each zeolite’s vessel during 8 h was achieved during the discharging with an airflow inlet at 20 °C, 10 g/kg of dry air of specific humidity and a flow rate of 180 m 3 /h. Some discrepancies between the experimental and simulation results were observed during both the charging and discharging tests, and were explained.

Je tiens donc à remercier Fréderic KUZNIK et Marc CLAUSSE pour leur lecture attentive de ce manuscrit et leurs remarques constructives. Merci à Yao AZOUMAH et Jean-Luc HUBERT d'avoir accepté d'endosser le rôle d'examinateur. Je souhaite remercier Lingai LUO DONG et Benoit STUTZ, Directeurs successifs du Laboratoire Locie pour leur accueil chaleureux et pour avoir facilité mon intégration au sein des équipes de recherche. Ce manuscrit marque l'aboutissement de plusieurs années d'un travail ponctué de nombreux moments de joie et, il faut bien l'avouer, de quelques moments de désespoir et de tristesse, bien vite surmontés, tant cette expérience fut enrichissante. Durant ces années, le plaisir que j'ai eu à réaliser ce travail fut intimement lié à celui que j'ai eu à côtoyer nombre de personnes que je me dois à présent de remercier. Je souhaiterais remercier en premier lieu Mesdames Lingai LUO DONG et Nolwenn LE PIERRES, pour la confiance qu'elles m'ont accordée lorsqu'elles m'ont confié ce travail de recherche. Jřexprime ma profonde gratitude pour leur générosité, leur patience, leur disponibilité bienveillante et leurs encouragements durant ces trois années de thèse.

En effet, ces systèmes sont très prometteurs dans la mesure où ils permettent un stockage de chaleur sur de longues périodes (le stockage est réalisé sous forme de potentiel chimique) et offrent des densités énergétiques importantes (jusqu'à 230 kWh/m3 de matériau en moyenne) en comparaison aux systèmes classiques comme le stockage par chaleur sensible (qui, pour le cas de l'eau, dispose d'une densité énergétique moyenne d'environ 81 kWh/m3 de matériau pour une variation de 70°C) et le stockage par chaleur latente (qui atteint des densités énergétiques de 90 kWh/m3 de matériau).La présente thèse vise à étudier les performances d'un système de stockage de chaleur par sorption à base de zéolithe 13X intégré à un bâtiment type basse consommation.

The model involves coupled heat and mass transfer inside the reactive porous bed and is used to study the effect of parameters such as the specific humidity and the temperature of humid air on the heat released by the reactor bed during the adsorption phase and the water content of zeolites at the end of the desorption phase. The results of the dynamic simulations quantify on the one hand the increase of the heat released by the reactor bed with the increase of the water content of the supplied air during the adsorption phase and on the other hand, the decrease of the water content of the zeolites at the end of the desorption phase with the increase of the temperature of the supplied air and the decrease of its specific humidity.

This trend has a major impact on state budgets and domestic trade balances, while also limiting the access of rural inhabitants to modern energy services. Contribution of biofuels in stabilizing the energy sector, influences ongoing negotiations on the global dynamics of climate change, the reduction in greenhouse gas (GHG) emissions and sustainable development. The question of biofuels as an alternative energy thus depends on international, national and local considerations. Biofuels represent opportunities, e.g., energy independence and security, new national income and employment sources, as well as potential food security problems. African policy makers therefore need to make the right choices to guide the development of biofuel production and use. This article aims to support the development of a biofuel policy by reviewing the latest technical, economic, environmental and social knowledge so as to be able to evaluate the potential and limits of biofuels in Burkina Faso.

This paper reviews the thermal energy storage technologies suitable for building applications with a particular interest in heat storage materials. The paper provides an insight into recent developments on materials, their classification, their limitations and possible improvements for their use in buildings. Three major thermal energy storage modes (sensible heat, latent heat, thermochemical heat) are described emphasizing the main characteristics of the most suitable heat storage materials for each.
