Enhanced Geothermal Systems

Definition

Enhanced geothermal systems (EGS) are a type of geothermal energy technology that enhance the natural geothermal resources by injecting water into hot, dry rock formations to create steam for electricity generation. This technology expands the potential for geothermal energy extraction, allowing it to be utilized in areas where traditional geothermal resources are not readily available, thereby contributing to clean energy production and renewable resource development.
