EGS, AGS, and Supercritical Geothermal Systems: What’s the Difference?

Credit to Author: Sonal Patel| Date: Tue, 04 Apr 2023 13:52:20 +0000

The spectrum of geothermal technologies is quickly evolving. This supplement to POWER’s April 2023 feature, “Startups Are Shaking Up Geothermal Power’s Potential,” briefly explains the differences between some engineered geothermal systems. Conventional geothermal energy is largely produced by hydrothermal systems, which consist of hot water circulated in deep-seated permeable rocks. Resource temperature ranges from high (greater […]
