Assessment of different Sands potentiality to formulate an effective Thermal Energy Storage Material (TESM)

Abstract

his paper presents a review of solid particle size effect on thermocline storage performance for Concentrating Solar Power (CSP) storage systems. After an overview on the different process to store thermal energy we found that a particle size of 2cm diameter is better to achieve a good sensitive heat storage performance within a system call dual-medium thermocline (DMT). The thermal storage potential of different sands from Burkina Faso have been carried out to look at the possibility of making a filler material with 2cm diameter. However, two different sands (mining dune and river sand) properties have been assessed. The density of the two samples is more than with low mass losses at 700°C without any agglomeration at 900°C and 1000°C. This indicates that the mining sand samples from Bobo Dioulasso and Dune sand from Sahel region in Burkina (Oursi) have the potentials to be used to develop an effective thermal energy storage material or to store thermal energy at high temperature.
