Abstract: Bauxite-based proppants, commonly used in the fracking industry, are also employed in solid particle receiver types of Concentrated Solar Thermal (CST) technologies. However, fracking has been banned in many countries due to its environmental impact, leading to a decline in demand for proppants. As a result, the current proppant price of 1 €/kg is … Continue reading Published at Solar Energy Materials – Thermal and environmental durability of novel particles for Concentrated solar thermal technologies
