IIR documentSummary
High-performance energy storage is crucial to alleviate the mismatch between thermal energy generation and consumption, thus providing a feasible solution to realize the large-scale utilization of renewable energy. Owing to high energy storage density, insignificant heat loss, and relatively mature technology, absorption thermal energy storage (ATES) system has shown promising potential in thermal energy storage, especially in long-term storage. Thermal energy could be stably stored and then converted to controllable heating or cooling output whenever and wherever possible. In this work, performance evaluation of various working pairs in different ATES cycles has been carried out. Results show that the H2O/ionic liquids (ILs) present comparable performance with H2O/LiBr in single-stage ATES cycle. In the thermally pressurized ATES cycle, the energy storage performance of H2O/ILs is significantly improved. H2O/[Emim][Ac] exhibits an energy storage density of 134.5 kWh/m3, which is 26.4% higher than that of H2O/LiBr. This work presents a comprehensive investigation of working pairs and cycle configurations of ATES systems, which can serve as guidelines for high-performance absorption thermal energy storage.
