Geothermal energy has long been seen as a promising, but challenging, clean energy resource. Unlike wind or solar, geothermal requires finding heat hidden deep underground, often with little surface indication of where to look. Joel Edwards, co-founder and Chief Technology Officer of Zanskar, joins Climate Rising to explain how advances in geoscience, data science, and machine learning are transforming geothermal exploration. By combining publicly available geologic data with modern modeling techniques, Zanskar is working to reduce the risk and cost of finding new geothermal resources. The conversation explores how geothermal systems work, why exploration has historically been challenging, and how Zanskar’s approach is enabling “blind discoveries” - finding viable geothermal resources that lack surface expressions such as hot springs or geysers. Joel also discusses the economics of geothermal, the role of data centers as a potential catalyst for growth, and what it will take to scale the industry.
