The study provides a study on energy storage technologies for photovoltaic and wind systems in response to the growing demand for low-carbon transportation. Energy storage systems (ESSs) have become an emerging area of renewed interest as a critical factor in renewable energy systems. The technology choice depends essentially on system requirements, cost, and performance characteristics. Common types of ESSs for renewable energy sources include electrochemical energy storage (batteries, fuel cells for hydrogen storage, and flow batteries), mechanical energy storage (including pumped hydroelectric energy storage (PHES), gravity energy storage (GES), compressed air energy storage (CAES), and flywheel energy storage), electrical energy storage (such as supercapacitor energy storage (SES), superconducting magnetic energy storage (SMES), and thermal energy storage (TES)), and hybrid or multi-storage systems that combine two or more technologies, such as integrating batteries with pumped hydroelectric storage or using supercapacitors and thermal energy storage. These different categories of ESS enable the storage and release of excess energy from renewable sources to ensure a reliable and stable supply of renewable energy. The optimal storage technology for a specific application in photovoltaic and wind systems will depend on the specific requirements of the system. It is important to carefully evaluate these needs and consider factors, such as power and energy requirements, efficiency, cost, scalability, and durability when selecting an ESS technology.

“…Due to this great potential, several pure salt hydrates and composite systems with different salts were investigated: e.g., LiBr [6], MgSO 4 [7], CaCl 2 [8], SrCl 2 [9], and LiCl [10]. Among them, LiCl is one of the salts that raised more interest for low/medium temperature (i.e., below 120 • C) TES application [11]. Indeed, the high-energy density of the LiCl-based system makes it an attractive candidate from the heat storage capacity cost perspective, thus resulting in one of the materials with a lower cost per kWh stored (~6 €/kWh) [12].…”

Morphological Observation of LiCl Deliquescence in PDMS-Based Composite Foams

The LiCl-based heat storage system exhibits a high-energy density, making it an attractive and one of the most investigated candidates for low-temperature heat storage applications. Nevertheless, lithium chloride, due to its hygroscopic nature, incurs the phenomenon of deliquescence, which causes some operational challenges, such as agglomeration, corrosion, and swelling problems during hydration/dehydration cycles. Here, we propose a composite material based on silicone vapor-permeable foam filled with the salt hydrate, hereafter named LiCl-PDMS, aiming at confining the salt in a matrix to prevent deliquescence-related issues but without inhibiting the vapour flow. In particular, the structural and morphological modification during hydration/dehydration cycles is investigated on the composite foam, which is prepared with a salt content of 40 wt.%. A characterization protocol coupling temperature scanned X-ray diffraction (XRD) and environmental scanning electron microscopy (ESEM) analysis is established. The operando conditions of the dehydration/hydration cycle were reproduced while structural and morphological characterizations were performed, allowing for the evaluation of the interaction between the salt and the water vapor environment in the confined silicon matrix. The material energy density was also measured with a customized coupled thermogravimetric/differential scanning calorimetric analysis (TG/DSC). The results show an effective embedding of the material, which limits the salt solution release when overhydrated. Additionally, the flexibility of the matrix allows for the volume shrinkage/expansion of the salt caused by the cyclic dehydration/hydration reactions without any damages to the foam structure. The LiCl-PDMS foam has an energy density of 1854 kJ/kg or 323 kWh/m3, thus making it a competitive candidate among other LiCl salt hydrate composites.

“…In most of these investigations, Li compounds are used. However, the demand for Li compounds will increase in the future 22) , and the price of Li compounds is high because of the cost of refining Li compounds from their raw materials such as ore and brine 23) . Therefore, reducing the amount of Li compounds used as additives is desirable.…”

Dehydration Reactivity of Mg(OH)<sub>2</sub> Containing Low Amounts of Li-additives for Thermochemical Energy Storage

2022

Synopsis: Mg(OH) 2 is a chemical heat storage material suitable for the utilization of unused heat at 300-400 °C. It has been reported that the addition of Li compounds to Mg(OH) 2 promotes the dehydration of Mg(OH) 2 . However, the demand for Li compounds has increased in recent years and the price of Li compounds is relatively high. Therefore, the purpose of this study is to enhance the dehydration reactivity of Mg(OH) 2 with a small amount of Li. In this study, several alkali metal chlorides and hydroxides such as LiCl and NaOH or KOH were added to Mg(OH) 2 , and the dehydration reactivity and composition of the corresponding mixtures were investigated. The samples prepared using 5 mol% LiCl and 10 mol% NaOH (LiCl-5NaOH-10) or 2.5 mol% KOH (LiCl-5KOH-2.5) showed excellent dehydration reactivity and were dehydrated below 300 °C with comparatively lower amounts of Li compounds than those reported in previous studies. These results indicate that these samples have great potential as low-cost chemical heat storage materials.However, the stabilities of these samples in air are quite different. Based on X-ray diffraction analysis of the data, the results are associated with the composition of Cl
