Abstract: [Objectives]Under the Dual-Carbon strategy, energy storage plays a vital role in balancing energy supply and demand in new energy systems and enhancing energy use flexibility on the user side. As a key form of energy storage, thermal energy storage is critical for solar energy utilization, flexible peak shaving on the power generation side, and the localized consumption of wind–solar–thermal energy. The successful implementation of thermal energy storage (TES) depends on the coordinated optimization of storage materials, devices, and systems. Among various TES technologies, thermochemical adsorption energy storage stands out due to its advantages of high energy density, wide operating temperature range, and negligible thermal loss, showing great promise in future energy systems. However, challenges remain, such as poor cyclic stability and adsorption hysteresis of materials, difficulty in matching thermodynamic cycles with varying heat source temperatures, low heat and mass transfer performance in reactors, and limited climate adaptability of the storage systems. [Methods]Therefore, this paper summarizes the latest research progress in improving the performance of thermochemical adsorption energy storage by addressing key issues related to its principles, materials, cycles, devices, and systems. [Conclusions]It explores novel material design strategies, constructs highly adaptable thermochemical storage cycles, optimizes reactor structures, and proposes system-level designs, providing new insights for enhancing thermal storage and supply under low-temperature and fluctuating heat source conditions, with the aim of accelerating the realization of the dual carbon goals.
