Abstract

Thermochemical energy storage (TCES) is a method of storing energy by using reversible chemical reactions to absorb and release heat. TCES materials generally possess the highest volumetric energy density and negligible heat losses during cyclic charging/discharging when compared with sensible and latent heat storage materials. The controllable charging/discharging processes in the TCES materials make them suitable for long-term or seasonal thermal energy storage, which can help improve the resilience of the existing energy system and built environment. In recent years, there has been a growing number of studies on the use of cementitious materials as low-cost and low-carbon thermochemical energy storage materials, including ettringite, calcium aluminate cements, and geopolymers. In this study, the state-of-the-art development using cementitious materials for thermo-chemical energy/heat storage applications is reviewed and systematically compared in terms of their compositions, energy storage operating conditions, and energy storage performance. Technical recommendations are proposed for standardised characterisation and testing protocols of these cementitious (composite) materials used for thermochemical heat storage. The current research challenges and future research needs in this field are also discussed.

胶凝复合材料化学储热实验研究综述：RILEM tc299 - tes报告。

热化学储能（TCES）是一种利用可逆化学反应来吸收和释放热量的储能方法。与显热和潜热储存材料相比，TCES材料通常具有最高的体积能量密度和可忽略的循环充放电热损失。TCES材料的可控充放电过程使其适合长期或季节性储热，有助于提高现有能源系统和建筑环境的弹性。近年来，利用胶凝材料作为低成本、低碳的热化学储能材料的研究越来越多，包括钙矾石、铝酸钙水泥、地聚合物等。在这项研究中，使用胶凝材料进行热化学能/储热应用的最新发展进行了回顾，并系统地比较了它们的成分，储能操作条件和储能性能。提出了用于热化学储热的这些胶凝（复合）材料的标准化表征和测试方案的技术建议。讨论了该领域当前的研究挑战和未来的研究需求。
