Storage of thermal energy can be important for compensating the mismatch between demand and supply of energy, especially due to fluctuating renewable energy sources. Within this study, two different system concepts of thermal energy storage involving sorption effects are analysed in a simulation study with the aim of increasing storage efficiency and storage density compared to known systems. Both systems indicate a possible benefit in energy density and storage efficiency but it is also analysed how the choice of system boundary and temperature requirements of the use case influence these two figures of merit.

级联吸附蓄热与吸附辅助蓄水储水密度及效率比较

热能储存对于补偿能源供需之间的不匹配非常重要，特别是由于可再生能源的波动。在这项研究中，在模拟研究中分析了两种不同的热能存储系统概念，涉及吸附效应，目的是与已知系统相比提高存储效率和存储密度。这两个系统都表明在能量密度和存储效率方面可能有好处，但还分析了系统边界的选择和用例的温度要求如何影响这两个品质因数。
