Superhot Rock Geothermal: A Vision for Zero-Carbon Energy "Everywhere"

Clean Air Task Force

October 2021

Superhot rock (SHR) has been called the “holy grail” of geothermal energy—because, in most of the world, SHR could provide competitive, zero-carbon, dispatchable power and support zero-carbon hydrogen fuel production. It is one of the very few high-energy-density, zero-carbon resources that could replace fossil energy around the globe. With significant private and public investment, SHR could plausibly be commercialized within 10-15 years. John Herter and Eric Ingersoll of Terra Praxis contributed to this important Clean Air Task Force (CATF) report.
