Researchers turn industrial waste into battery for renewable energy storage
Scientists have validated waste materials like broken roof tiles and cement dust as viable thermal storage media, stable at 800°C through hundreds of heating cycles. This breakthrough could dramatically reduce costs for grid-scale energy storage systems, making it cheaper to store excess solar and wind power for later use.
Originaltitel: D3.2 – Enhanced upcycled high temperature TES materials
This deliverable presents the results of long-duration and cyclic thermal tests conducted on waste ceramic materials and industrial by-products — including clinker, roof tiles, hollow bricks, and ashes — to evaluate their suitability as high-temperature Thermal Energy Storage (TES) media. It assesses material structural and weight stability under prolonged exposure at 800°C and repeated thermal cycling between 400°C and 800°C, and provides final recommendations for material selection and enhancement techniques to support the integration of upcycled TES materials into commercialised TES systems.
