Referring to the Energy Efficiency Directive, waste heat storage represents a key issue for helping EU to reach 20% energy efficiency target by 2020. A growing interest matured on MgO/H2 O/Mg(OH)2 thermochemical system that stores heat (200-400°C) through the dehydration of Mg(OH)2 and releases stored heat when required by reversible hydration of MgO in presence of water vapour.

Abstract
Referring to the Energy Efficiency Directive, waste heat storage represents a key issue for helping EU to reach 20% energy efficiency target by 2020. A growing interest matured on MgO/H2 O/Mg(OH)2 thermochemical system that stores heat (200-400°C) through the dehydration of Mg(OH)2 and releases stored heat when required by reversible hydration of MgO in presence of water vapour. For the future development of this technology, the improvement of the active medium performances is a key issue. In this study, exfoliated graphite (EG)-Mg(OH)2 hybrid materials are synthesized by two preparation methods: Deposition-Precipitation (DP) and Reverse Deposition-Precipitation (RDP).Pubblicazioni consigliate
