Salt Hydrate Adsorption Material-Based Thermochemical Energy Storage for Space Heating Application: A Review

“…This type of composite is preferred in medium-and low-temperature TCES systems. After a compromise between the largest amounts of salt and the reaction heat, the activated carbon-MgSO 4 (30 wt.% MgSO 4 ) composite in the latest research [201] was proven to be better for completing eight cycles of adsorption/desorption stably (Figure 19d) and had a higher reaction enthalpy of 1324 kJ•kg −1 during adsorption. A new composite material hydroxyapatite-MgSO 4 containing two salt contents of 5 wt.% and 20 wt.% was prepared and characterized, and the results indicated that the porous matrix hydroxyapatite greatly improved the slow kinetics of MgSO 4 and considerably reduced the reaction time.…”

Towards industrial-scale adsorptive heat storage systems: From state-of-the-art selected examples to preliminary conception guidelines

“…More generally, the current trend in novel material developments aims at the energy storage density enhancement [18]. The development of highperformance, cost-effective TCMs is crucial because they should be industrially and economically attractive (e.g., easily scalable, cost-effective) and prepared from renewable and abundant natural resources [20].…”
