Cracking the Code of Hidden Heat
Geothermal power is a simple idea with notoriously difficult implementation. The Earth’s interior constantly produces heat; where accessibility and temperature align, the energy can be tapped to spin turbines, generating round the clock power with no combustion and no carbon emissions. The challenge is locating high temperature reservoirs before drilling begins. For conventional geothermal, an exploratory well is an expensive gamble ranging from hundreds of thousands to several million dollars.
Historically, many of the United States’ most productive geothermal fields were discovered by accident oil drillers encountering steam, agricultural wells tapping unexpected hot water, or ranchers stumbling upon surface activity. The few systematic attempts, such as a 1970s federal grid drilling campaign in Nevada, produced limited success because researchers lacked meaningful subsurface heat flow data.
AI reshapes the equation. Edwards and cofounder Carl Hoiland built Zanskar on the idea that geothermal resources are far more abundant than government estimates suggest but only if a new way of finding them emerges. “We think there’s ten times more out there than anyone thought,” Hoiland says. “And each site can be dramatically more productive than earlier estimates predicted.”
Zanskar’s algorithms trace their lineage to a body of academic work led by scientists like James Faulds of the University of Nevada, Reno. Faulds spent years cataloging attributes of known geothermal systems fault offsets, structural intersections, heat flow anomalies and used those patterns to predict where blind systems might exist. His research helped locate a blind geothermal system in 2018, validating the approach but not advancing it to commercial scale.
Zanskar has expanded that methodology, feeding its models far larger volumes of geospatial, structural, and geophysical data. During surveys, the company’s geologists recently identified a geothermal anomaly west of Tonopah, indicating high heat flow. The AI system then pinpointed optimal well locations for testing. Drilling confirmed that the anomaly was not a mirage: Big Blind was real.
Its 250 degree Fahrenheit temperatures far surpass minimum requirements for utility scale power and contrast sharply with other regional areas that require drilling to depths of 10,000 feet or more. Those deeper resources are viable for next generation geothermal technologies being developed by startups like Fervo Energy, but they require more complex and costlier engineering.
By contrast, Zanskar’s resource can support a traditional geothermal plant something the industry knows how to build quickly, reliably and at scale.
