The fundamental benefit of adopting TES in DH/DC systems is the ability to decouple heat/cold generation from consumption. When demand exceeds supply, whether, on a short or long-time scale, the primary purpose of TES is to store the highest renewable energy production for later heat/cold consumption.
Energy Storage explains the underlying scientific and engineering fundamentals of all major energy storage methods. These include the storage of energy as heat, in phase transitions and reversible chemical reactions, and in organic fuels and hydrogen, as well as in mechanical, electrostatic and magnetic systems.
