A new era for clean, reliable power is here.
CARBO is proud to be a part of a record-setting achievement. Mazama Energy has announced the successful completion of the world’s hottest Enhanced Geothermal System (EGS), marking a historic milestone in clean energy development. This first-of-its-kind well reached subsurface temperatures of 330°C, proving the feasibility of harnessing deep superhot rock to generate continuous, carbon-free power. CARBO’s advanced ceramic proppants were utilized for this project, providing the strength and thermal stability needed to maintain conductivity in extreme geothermal conditions.
According to the GlobeNewswire release, this project represents a major step forward for affordable, renewable baseload energy on a global scale.
A Defining Moment for Geothermal Innovation
The Mazama project represents a major leap forward for the geothermal industry. By successfully engineering permeability in ultra-hot, impermeable rock, Mazama proved that EGS can now tap into heat resources once thought unreachable. This achievement positions EGS as a cornerstone of the future renewable mix, one capable of providing continuous electricity with minimal land and water use.
Unlike conventional geothermal systems that rely on natural steam or water reservoirs, EGS creates engineered fracture networks that circulate water through deep rock formations to extract heat. This approach opens access to vast untapped geothermal potential in regions far beyond traditional volcanic zones.
Building the Foundation for Long-Term Success
Super-Hot Rock EGS technology depends on maintaining fracture conductivity under extreme temperature and stress conditions to sustain energy production over decades. At the Mazama site, specialized materials were used to ensure those demanding conditions could be achieved and maintained, enabling reliable, long-term heat exchange deep underground.
We are proud to have contributed to this historic achievement. Our advanced ceramic proppants, engineered for high thermal stability and strength, supported the creation of a durable fracture network capable of withstanding the superhot, high-pressure environment needed for efficient geothermal circulation.
A Shared Vision for a Cleaner Future
The success of Mazama’s EGS well marks more than a technological accomplishment. It represents a turning point for the energy industry. As the geothermal sector continues to evolve, projects like this prove that innovation and collaboration across industries can unlock solutions to some of the world’s toughest energy challenges.
At CARBO, we look forward to continuing to play a role in advancing geothermal innovation and supporting partners who are redefining what’s possible beneath the Earth’s surface.
