New geomaterial for energy storage - mechanical and thermal properties

The development of renewable energy sources requires the development of technologies and further expansion of energy storage infrastructure on global markets. One type of energy storage is thermal energy storage(TES). Ongoing researches aim at improving the efficiency of storage and heat transfer in such installations. An important element of these installations is the reservoir that accumulates thermal energy. The following work presents research on new geomaterials based on waste materials, mining raw materials and mixed materials based on them, which could potentially be used as materials for the construction of a packed bed or resevoir that stores thermal energy in TES. These materials, due to the possibility of forming almost any shapes, should exceed the efficiency of aggregate minerals. Additionally, their utilization can partially or fully eliminate mining waste, thereby promoting circular economy principles.
