“…Alfed et al [48] and Kato et al [49] studied the use of zeolite in seasonal storage of energy and found that zeolites alone in storing solar energy will be expensive. On the other hand, the use of single material like magnesium sulphate heptahydrate (MgSO 4 .7H 2 O) showed great potential in energy storage by endothermic dehydration of the salt via obtained heat from solar collector.…”

Energy consumption in kingdom of Saudi Arabia (KSA) is growing rapidly due to economic development with raised levels of population, urbanization and living standards. Fossil fuels are currently solely used to meet the energy requirements. The KSA government have planned to double its energy generating capacity (upto 120 GW) by 2032. About half of the electricity capacity of this targeted energy will come from renewable resources such as nuclear, wind, solar, waste-to-energy (WTE) etc. Natural zeolites are found abundantly in KSA at Jabal Shamah occurrence near Jeddah city, whose characteristics have never been investigated in energy related applications. This research aims to study the physical and chemical characteristics of natural zeolite in KSA and to review its potential utilization in selected WTE technologies and solar energy. The standard zeolite group of alumina-silicate minerals were found with the presence of other elements such as Na, Mg and K etc. A highly crystalline structure and thermal stability of natural zeolites together with unique ion exchange, adsorption properties, high surface area and porosity make them suitable in energy applications such as WTE and solar energy as an additive or catalyst. A simple solid-gas absorption system for storing solar energy in natural zeolites will be a cheap alternative method for KSA. In anaerobic digestion (AD), the dual characteristics of natural zeolite like Mordenite will increase the CH 4 production of organic fraction of municipal solid waste (OFMSW). Further investigations are recommended to study the technical, economical, and environmental feasibility of natural zeolite utilization in WTE technologies in KSA.

“…THS (thermochemical heat storage) is a promising alternative to traditional sensible and latent heat storage since it provides higher energy storage density, longer storage time and lower thermal losses [3,10,11]. THS is based on a reversible chemical reaction…”

“…They are especially important for instable energy supply or demand that often leads to wasting huge amounts of middletemperature (250e500 C) heat in industry, transport and power engineering [1,2], including combined heat/power [3,4] and renewable energy sources [5,6]. For example, an enormous quantity of heat (53.8,10 6 GJ) from hot stoves for steel production was wasted at temperature of z300 C [2].…”

“…Particularly focusing on thermal energy, sensible [5] or latent [6] heat storage systems are the most studied and established solutions in the field. However, due to unavoidable energy losses, those approaches are often not suitable for long-term applications [7]. On the contrary, storage systems based on sorption phenomena show high energy density, negligible heat losses and allow repetitive storage operations [8].…”

We report numerical protocols for describing the water uptake process into microporous materials, with special emphasis on zeolite crystals. A better understanding and more predictive tools of the latter process are critical for a number of modern engineering applications ranging from the optimization of loss free and compact thermal storage plants up to more efficient separation processes. Water sorption (and desorption) is indeed the key physical phenomenon to consider when designing several heat storage cycles, whereas water infiltration is to be studied when concerned with sieving through microporous materials for manufacturing selective membranes (e.g. water desalination by reverse osmosis). Despite the two quite different applications above, in this article we make an effort for illustrating a comprehensive numerical framework for predicting the engineering performances of microporous materials, based on detailed atomistic models. Thanks to the nowadays spectacular progresses in synthesizing an ever increasing number of new materials with desired properties such as zeolite with various concentration of hydrophilic defects, we believe that the reported tools can possibly guide engineers in choosing and optimizing innovative materials for (thermal) engineering applications in the near future.
