Thermo-chemical energy storage technology is a promising technology used in space heating and cooling applications. Salt hydrates show high energy storage density and appeared as encouraging candidate for thermal energy storage. Nevertheless, lack of stability/ repeatability are the main issue. The current study focuses on MgSO4-based hybrids for thermal energy storage. The structural properties of the hybrid is measured by SEM, and the adsorption/regeneration characteristics are measured by a lab scale thermal energy storage apparatus. The hybrid shows high energy storage density ~ 150 kWh/m3at 50% relative humidity and 120°C regeneration temperature.
