Renewable energy has the drawback of intermittent power generation, and it should be linked to an energy storage system. However, the efficiency and density of the conventional thermal energy storage technologies are low. Herein, for building applications, CO₂ capture-driven thermal battery has been developed using solvents composed of amine-functionalized mesoporous silica (3-APTES-SBA-15) and an amine absorbent (MEA). The thermal energy is discharged through the exothermic reaction of amine-CO. When the renewable energy is supplied to the battery, amine-CO₂ bonds are broken, which corresponds to charging process. 3-APTES-SBA-15/MEA presents a superior energy storage density of 2.187 kJ/g and an efficiency of 91.5%. It is sufficient for producing heating/hot water considering the discharging temperature, and there is no loss even if stored for a long time. The thermal battery system presents a coefficient of performance of 0.66 and a thermal energy storage density of 0.57 kJ/g. When the thermal battery is combined with solar thermal energy harvesting system, the thermal and electric energy consumptions are reduced by 22.0% (477.9 MJ/m²) and 19.6% (156.9 MJ/m²), respectively. The CO₂ capture-driven thermal battery will contribute to manage renewable energy and reduce grid energy consumption for building applications.

可再生能源具有间歇性发电的缺点，应与储能系统相连。然而，传统热能存储技术的效率和密度较低。在此，对于建筑应用，CO ₂捕获驱动热电池已使用由胺官能化介孔二氧化硅 (3-APTES-SBA-15) 和胺吸收剂 (MEA) 组成的溶剂开发。热能通过胺-CO 的放热反应释放。当可再生能源供应给电池时，胺-CO ₂键被破坏，这对应于充电过程。3-APTES-SBA-15/MEA 具有 2.187 kJ/g 的优异储能密度和 91.5% 的效率。考虑到排放温度，足以产生加热/热水，即使长时间存放也不会造成损失。热电池系统的性能系数为0.66，热能存储密度为0.57 kJ/g。当热电池与太阳能热能收集系统相结合时，热能和电能消耗分别降低了22.0%（477.9 MJ/m ²）和19.6%（156.9 MJ/m ²）。CO ₂捕获驱动的热电池将有助于管理可再生能源并降低建筑应用的电网能耗。
