Explore the potential of superhot rock geothermal energy

Superhot rock energy is an emerging energy source that will harness massive stores of renewable energy by pumping water deep into hot underground rocks, where it naturally heats up and then returns to the surface as steam. That steam could be used to produce carbon-free electricity, clean hydrogen, and other high-energy-intensity products. 

Traditional geothermal systems in operation today only work in regions where hot water naturally exists near the earth’s surface. By contrast, superhot rock energy systems will reach kilometers deeper into the earth and don’t require underground sources of water, making them viable across the globe. 

Superhot rock energy will provide always-on clean firm energy with a capacity factor of 90% or higher. It will also have a low land footprint compared to other sources of energy. And it is available around the world. 

With appropriate investment to overcome technological hurdles, superhot rock energy could reach commercial scale and potentially compete with unsubsidized market prices. Furthermore, the research necessary to fully utilize this energy does not require a scientific breakthrough, rather it requires concerted engineering practice and iteration in the field. If this is achieved, superhot rock energy could provide clean firm power at scale without the import risk and land-use footprint of other energy sources.
