Recent developments on open thermochemical energy storage towards decarbonised building space heating and cooling

Thermal energy storage (TES) is one of the key technologies to achieve sustainability and mitigate the global warming impact. Among all TES methods, thermochemical energy storage (TCES) presents promising features including relatively high energy density and long-term heat storage potential. Accordingly, this study presents an overview with a focus on reaction and sorption-based open TCES systems. Within the study, material, reactor and process integration aspects of open TCES systems both for heating and cooling applications are evaluated. This study could provide important insights on future development of TCES materials and technologies.
