Zanskar is leveraging advanced artificial intelligence to unlock an estimated 1 terawatt of untapped geothermal energy potential, aiming to transform exploration by identifying and validating high-yield sites across the U.S. West.
AI-Driven Exploration Strategy
To pinpoint new geothermal resources, Zanskar utilizes supervised machine learning models. By feeding these models diverse datasets—including information from previous accidental discoveries—the startup identifies high-potential locations before dispatching field teams to conduct physical validation of the findings.
Bayesian Learning and Simulation
Once a site is identified, the company transitions to a specialized development strategy using “Bayesian evidential learning” (BEL). In this framework, existing data informs a series of assumptions, or “priors,” which the models then systematically test and falsify to generate precise probabilities. To address remaining data gaps, the startup employs a proprietary geothermal simulator designed to provide comprehensive site modeling.
Proven Success and Future Scaling
The effectiveness of this methodology has already been demonstrated in practice. Previous funding rounds enabled the exploration of three sites, all of which yielded successful results. “Three of three,” noted Zanskar co-founder and CTO Joel Edwards. “What does it look like when you try 10?”
Bridging the Capital Gap
Zanskar currently maintains a pipeline of sites capable of supporting at least a gigawatt of generating capacity, with a primary focus on the U.S. West. Leadership aims to confirm at least 10 sites to attract project finance investors, who offer lower-cost capital compared to traditional venture capital. This strategic move is intended to help the company navigate the “valley of death” that frequently stalls climate tech startups.
The Future of Geothermal Exploration
While leadership acknowledges that the challenges of geothermal resource discovery remain complex, there is strong confidence that the current trajectory is correct. “We now know this is the future of exploration,” said Hoiland. “This is going to change geothermal in very short order.”
