GTO Technologies is committed to developing and commercializing innovations that unlock the full potential of carbon-free electricity. Our mission is to strengthen our partnership with the Colorado School of Mines to address critical technological challenges that hinder the economic growth of advanced geothermal and geologic hydrogen solutions. We aim to transform these technologies from concept to market, enabling the world to harness clean, carbon-free energy.

Our key technologies make Enhanced Geothermal Systems (EGS) cost-effective by controlling flow. Our patented systems, developed with a $5.3 million DOE FORGE grant, fix EGS problems like short circuits and early cooling. We create underground heat exchangers by providing the access points for fracture stimulation and then control the flow rate in each fracture. The GTO Technologies system can triple EGS power output and boost project profits by $800 million per project.
