Stanford Study Highlights Benefits of Enhanced Geothermal Systems for Clean Energy Transition
A Stanford University study reveals that Enhanced Geothermal Systems (EGS) can significantly aid the clean energy transition by reducing the infrastructure needs for wind, solar, and battery systems while keeping electricity prices competitive. Integrating EGS could lower onshore wind capacity by 15%, solar by 12%, and battery storage by 28%, resulting in a 60% reduction in clean energy costs compared to fossil fuels. The study also forecasts a substantial decrease in EGS costs by 2035, driven by advancements in drilling technology.

Enhanced Geothermal Systems (EGS) leverage deep Earth heat with significantly lower infrastructure requirements compared to other renewables. A Stanford University study in Cell Reports Sustainability indicates that EGS can substantially reduce the need for wind, solar, and battery infrastructure while maintaining competitive electricity prices.
The study found that integrating EGS, even at a 10% electricity contribution, decreases onshore wind capacity needs by 15%, solar capacity by 12%, and battery storage requirements by 28%. Overall land use for energy drops from 0.57% to 0.48% of the total area in the considered countries.
Clean energy costs could decrease by approximately 60% compared to fossil fuels, with social costs reducing by 90% when factoring in health and climate impacts. EGS may also support off-grid data centers. Experts predict a significant decline in EGS costs by 2035 due to improved drilling speeds.
