“…The different clays studied in Burkina Faso contain mainly kaolinite (>40 wt%), illite (>13 wt%), quartz (>18 wt%) and rutile (1 wt%) [39]. The chemical composition of the CBA used is reported in Table 1 and size distribution of dune and mining sand is reported in [26] [40].…”

“…To achieve more effective storage efficiency as reviewed in [26], the thermocline should be thin, and an optimum thickness would be achieved with particle dimeter less than 3 cm. This optimum point reached was as result of the heat transfer process that existed between the heat transfer fluid and the particle surface, which depends on the particle size [25] [27].…”

In this paper, the mechanical and thermal properties of a sand-clay ceramic with additives coal bottom ash (CBA) waste from incinerator coal power plant are investigated to develop an alternative material for thermal energy storage (TES). Ceramic balls are developed at 1000˚C and 1060˚C using sintering or firing method. The obtained ceramics were compressed with a compression machine and thermally analyse using Decagon devise KD2 Pro thermal analyser. A muffle furnace was also used for thermal cycling at 610˚C. It was found that the CBA increased the porosity, which resulted in the increase of the axial tensile strength reaching 3.5 MPa for sand-clay and ash ceramic. The ceramic balls with the required tensile strength for TES were selected. Their volumetric heat capacity, and thermal conductivity range respectively from 2.4075 MJ•m −3 •˚C −1 to 3.426 MJ•m −3 •˚C −1 and their thermal conductivity from 0.331 Wm −1 •K −1 , to 1.014 Wm −1 •K −1 depending on sand origin, size and firing temperature. The selected formulas have good thermal stability because the most fragile specimens after 60 thermal cycles did not present any cracks. These properties allow envisioning the use of the ceramic balls developed as filler material for thermocline thermal energy storage (structured beds) in Concentrating Solar Power plants. And for other applications like solar cooker and solar dryer.

“…Concentrating solar power (CSP) technology is not yet developed in Sahelian countries or is still less known, while solar thermal technologies are the worthy investment option to provide the world with 25% of the electricity needed by 2050 [2]. In addition to the lack of data on CSP technologies in Sahelian countries, the technology is still costly [3]. A CSP plant consists of solar collectors (solar field), a storage system, and a power block.…”

“…TES cost is further reduced by replacing an important part of the heat transfer fluid (HTF) by low cost TES materials (TESM or filler materials) [14]. However, thermocline energy storage has some issues like outlet temperature variation and filler material size and geometry, strong thermos-mechanical stress and incompatibility between HTF and TESM and [15][16][17][18][19]. Fluid can be used as HTF or thermal energy storage.…”

“…In addition, with their good thermal properties, rocks like Dolerite, Rhyolite and quarzitic sandstone have high storage temperature of up to 600°C [33,36]. However, natural rock shape is uncontrollable and big, which can reduce the performance of TES [16]. Concretes can face this issue of size and shape but limited to 400 °C as working point.…”

Valorisation of local and low-cost eco-materials have become an imperative for the sustainable development of Concentrating Solar Power (CSP) in West Africa. In this study, the compatibility tests were carried out. These involve the application of jatropha curcas oil (JCCO) and ceramic balls, which were developed from clay coal bottom ash and sands with a focus on Burkina dune sand ceramic. The aim was to assess the applicability of using JCCO as heat transfer fluid in CSPs with direct thermocline thermal energy storage. The tests involve the use of a small container to put in contact with Jatropha oil with ceramic balls for 2160 hours and at 210 °C. From the chemical properties’ analysis, the peroxide value in the oil decreases with aging time while the acidity increase. However, the acidity remains below the limited value that is 25 mg KOH.g-1. Therefore, thermal properties that drive heat transfer and rheological properties (density, thermal conductivity, kinematic viscosity and so on) were not adjusted significantly at the storage temperature (of about 210°C). Thermal stability temperature decreased to 261.93°C for the oil aged alone as against 263.41 °C for the one that was put in contact with filler material. In the nutshell, there is no incompatibility between JCCO, and the new thermal energy storage material (TESM) developed. These couple of materials could be suitable for thermocline energy storage in CSP plant and for other applications like there use in solar cooker box.
