The subsurface can be heated and used as a medium for thermal energy storage. Synthetic Geothermal Reservoirs (SGR) use the subsurface as a medium for the storage of heat collected in concentrated solar collectors or energy from wind turbines to reliably produce on-demand electrical power using the recovered heat.
