Report: Powering the Future -- What 50 Years of Enhanced Geothermal Teaches Us Today

A report published in September 2025 from Clean Air Task Force (CATF) finds that Enhanced Geothermal Systems are closer than ever to large-scale commercialization after more than five decades of development.

Drawing on a database of 103 historical and current EGS projects, the report documents steady improvement alongside recent step-change innovations that could enable EGS to scale rapidly and at lower cost if supported by sustained policy action, investment, and research.

“Fifty years of global Enhanced Geothermal Systems development have brought us to a turning point,” said Terra Rogers, Program Director for Superhot Rock Geothermal. “The progress documented in this report shows EGS advancing beyond the research phase toward becoming a commercially viable, scalable source of clean, reliable power and laying the groundwork for even higher-output superhot rock geothermal.”
