Development and thermochemical characterizations of vermiculite/SrBr2 composite sorbents for low-temperature heat storage

Performance characterizations and thermodynamic analysis of magnesium sulfate-impregnated zeolite 13X and activated alumina composite sorbents for thermal energy storage

“…However, carbon adsorbents do not have the preference for adsorption of water, which means that the impurities in the polluted air can displace water vapor from activated carbon in open systems [23]. The vermiculite composite sorbents impregnated with SrBr2 [32] and LiCl [33] have the predicted energy storage densities of 105 kWh m −3 and 224 kWh m −3 , respectively. The experimental study of an open TES system shows that vermiculite/CaCl2 is a promising material for low-temperature heat storage with the energy storage density of 120-160 kWh m −3 , but vermiculite/MgSO4 underperforms compared with the data on dehydration heat [34].…”

Assessment of the hydration/dehydration behaviour of MgSO4∙7H2O filled cellular foams for sorption storage applications through morphological and thermo-gravimetric analyses

“…Several different sorbent composites were proposed in the literature, varying both porous matrix and salt hydrate [19]. Among them, the most common matrices are silica gel [20], clays [21] and carbonaceous structures [21], while among the salt hydrates LiCl [22], MgSO 4 [23] [22] and SrBr 2 [21] [20], and CaCl 2 [24][25][26] were deeply investigated. The experimental results reported in the literature confirmed that these materials can achieve promising TES capacities, for instance, the composite LiCl/Vermiculite developed by Grekova et al [22] can reach up to 2.3 kJ/g under seasonal storage operating conditions.…”

Hybrid strontium bromide-natural graphite composites for low to medium temperature thermochemical energy storage: Formulation, fabrication and performance investigation

“…MgSO4, CaCl2 and LiBr) in different structural materials including zeolite, silica gel and activated carbon [12,17,18]. Composite TCS containing SrBr2, however, remains largely unexplored, and the published studies were primarily on energy storage density [19][20][21] or on the performance of pure SrBr2 at the reactor scale [8,22] [23]. To our knowledge, no studies have been published on linkage between the performance and structure of the composite TCS containing SrBr2the main motivation of this paper.…”
