Hot Dry Rock (HDR)

Hot Dry Rock (HDR) refers to a geothermal energy technology that taps into underground rocks with high temperatures but lacking significant water or steam. Engineers drill deep into these rocks to create an artificial geothermal reservoir by fracturing the rock and injecting water. The heated water then returns to the surface as hot fluid, which can be used to produce electricity or provide direct heating. HDR offers a way to access vast geothermal energy sources in regions without natural steam or water, making it a promising renewable energy option with minimal environmental impact.
