During the discharging cycle, thermal energy (heat) is extracted from the tank's bottom and used for heating purposes.
What is aquifer thermal energy storage?
Aquifer thermal energy storage (ATES): Dating back to the mid 1960s, this tech-nology uses an underground aquifer to store sensible heat thanks to the use of at least two hydraulically connected wells (one for cold water and the other one for hot water) and a heat exchanger that are used for groundwater extraction and injec-tion .
How does a water storage tank work?
Excess heat from solar heating is used to heat the water during the charging cycle, and the hot water is then pumped through the pipelines. The tubes carry thermal energy from the hot water to the gravel-water combination inside the storage tank.
