This presentation comes from the international polymer processing company REHAU. It provides information on their systems for underground thermal energy storage.
The principle behind the thermal storage system is to match the supply of renewable energy heat with demand for it from consumers. The presentation highlights the Drakes Landing Community in Canada which features 800 solar collectors which provide heat to underground thermals storage for 52 houses.
