A thermal energy storage system that uses sand to store and release heat, primarily intended for seasonal district heating.
Integrating intermittent renewable sources into a stable and reliable grid by providing long-term storage of heat from excess energy production.
Surplus renewable electricity heats sand in insulated silos. The heated sand stores the thermal energy, which can be released later as needed for district heating purposes.
The process involves sourcing sand, insulating silos, installing heaters, and setting up monitoring systems to ensure efficient operation.
Initial setup includes site preparation for the silos, installation of heating elements, insulation, and integration with renewable power generation sources. Ongoing processes involve regular maintenance and optimization of thermal transfer efficiency.
