Seasonal Thermal Energy Storage – HGL

Aquifer thermal energy storage (ATES) is a technology that can provide large-scale seasonal storage of cold and heat in natural underground sites. ATES relies on pumping heated (or cooled) fluids into the subsurface and then extracting those fluids for use during peak demand. However, all sites are not equal candidates for ATES systems.
