“…[1] The contactor is connected to solid-materials toraged evices, whiche nsure the storage of the sorbent and thus of the energy.T he size of the contactor is mainly governed by the thermal power that is to be stored/produced (e.g.,l ow-energy buildings in northwestern Europeo nly store/produce af ew kW and so require af ew tenthso fakg of sorbent), whereas the size of the reservoir dependso nt he annual heat demand (e.g.,afew thousandk Wh per year for low-energy buildings in northwestern Europe).

The energy-storage capacities of a series of water-stable porous metal-organic frameworks, based on high-valence metal cations (Al , Fe , Cr , Ti , Zr ) and polycarboxylate linkers, were evaluated under the typical conditions of seasonal energy-storage devices. The results showed that the microporous hydrophilic Al-dicarboxylate MIL-160(Al) exhibited one of the best performances. To assess the properties of this material for space-heating applications on a laboratory pilot scale with an open reactor, a new synthetic route involving safer, greener conditions was developed. This led to the production of MIL-160(Al) on a 400 g scale, before the material was shaped into pellets through a wet-granulation method. The material exhibited a very high energy-storage capacity for a physical-sorption material (343 Wh kg ), which is in full agreement with the predicted value.

“…For this reason, the availability of zeolites as an adsorbent was searched widely before. [42][43][44][45][46][47][48][49] Natural zeolites have been also used in many areas such as ecology, agriculture, livestock and poultry feeder, mining, aquaculture, petrochemical industries, energy recovery, alcohol, methyl chloride and ethyl ethane formation, cosmetic industry, and pollution control . 50 In the present paper, the first time in the literature, natural zeolite has been employed, experimentally tested, and evaluated as thermal storage material for PVT systems.…”

Summary In this study, the first time in the literature, natural zeolite has been employed for photovoltaic thermal (PVT) and experimentally tested as a thermal energy storage material. The main aim of the paper is to introduce natural zeolite as a heat storage material for PVT systems. The PVT systems integrated with phase change materials and natural zeolite were designed, the components of the system were explained, the thermodynamical modelling including the first and second laws was presented, the system performances were evaluated, performance parameters were investigated, energy and exergy efficiencies were determined, and economical analyses of each system were performed. Besides, all results were compared with a conventional PVT system. The average overall energy efficiency values for PVT experiments were 33% for paraffin, 37% for stearic acid, 40% for zeolite, and 32% for conventional PVT systems. The payback period of the PVT system with paraffin, zeolite, stearic acid, and conventional PVT was calculated as 10, 8, 9, and 9 years, respectively. The results show that the natural zeolite is a material with significant potential to be used for heat management in PVT for any meteorological condition.

“…Selection criteria are, for instance, a high heat storage density at favorable operating temperatures, sufficient output power, cycling stability, and low costs and low toxicity [1][2][3][4][5][6][7][8][9]. Examples of salt hydrates that could be used for heat storage are Na 2 S·5H 2 O (cf.…”

“…Examples of salt hydrates that could be used for heat storage are Na 2 S·5H 2 O (cf. [1][2][3][4]) and K 2 CO 3 ·1 1 ⁄2H 2 O [5], but there are many other candidate reactions [6][7][8][9]. Selecting a suited salt hydrate depends on a number of its properties, which are obtained from experimental data.…”

Featured Application: A tool for the selection of the most suited material systems for (reversible) thermal heat storage with respect to the envisaged use cases. Temperatures of dehydration and rehydration are needed, as well as the heat storage density for the realization of heat batteries.Abstract: Hygroscopic salts exhibiting fast and reversible hydration are promising systems for seasonal heat storage, providing the possibility of storing excess solar energy from the warm season for later use during the cold season. For heat storage, the salt is dehydrated with the available heat, and for heat recovery, the salt is rehydrated. There are many salt hydration transitions and for selecting the most suited ones with respect to the envisaged use cases, temperatures of dehydration and rehydration are needed, as well as the heat storage density. Estimation of these properties requires entropy and enthalpy changes of the transitions. Collections of hydration entropies and enthalpies have been published, but not all data seems reliable for various reasons, and it is often hard to access original sources and experimental conditions. For the necessary data validation, we propose the use of Trouton's rule, known to hold for the evaporation of classes of fluids. Besides data validation, Trouton's rule is useful for predicting heat storage densities and vapor pressures when only the transition enthalpy is known. We discuss the validity of Trouton's rule for salt hydration and ammoniation transitions by theoretical and experimental evidence on the available extensive data collections.
