sandTES - High Temperature Sand Thermal Energy Storage System

Due to the volatility of renewable energy generation, high-performant TES (thermal energy storage) systems are essential for the improvement of energy efficiency in renewable, industrial and residential energy systems. The novel sandTES of TU Wien is based on sand and uses the fluidization principle, thus creating a highly efficient heat exchanger, storing heat at high temperatures and in large quantities in a cheap and uncritical storage medium. The sandTES system is environmentally friendly and comprises features such as low investment costs, low operational costs and high availability.
