Abstract

The present chapter delves into various aspects of gas�solid pair-based thermochemical energy storage systems (TESSs), which offer a promising solution to reconcile the gap between the intermittent availability of thermal energy from renewable sources and the variable demand from users. It begins by elucidating the fundamental operating principles of TESSs, emphasizing the critical importance of selecting appropriate thermochemical storage materials (TSMs) for optimal system performance. The chapter categorizes and discusses diverse TSMs, detailing their intrinsic properties and potential applications, the significant challenges they present, as well as with potential solutions. Key factors influencing the performance of TSMs, such as solid�gas reaction equilibrium, reaction kinetics, and reaction rate expressions, are discussed. A thermodynamic analysis of the TESS operating cycle is provided, offering insights into system performance under various conditions, illustrated through a case study of a TESS for heating applications in cold climates. Additionally, the impact of reactor configuration on TESS performance is explored, comparing the advantages and challenges of various designs. The chapter concludes by exploring innovative applications of TESSs, including building heating, battery preheating in electric vehicles, and multifunctional metal hydride-based thermal batteries.
