Key Takeaways: Technological advancements in geothermal exploration and drilling are reducing uncertainty and lowering risk profiles, making private investors and lenders more willing to commit capital that was historically constrained by high costs and low success rates. These same advancements may generate proprietary technologies and defensible intellectual property, which may favor leading companies to secure capital advantages while potentially excluding competitors from future financing and development opportunities.
It is reported that “[o]ne of the main challenges of scaling geothermal power production is the fact that there are relatively few investors willing to finance exploratory drilling[ b]ecause the exploratory drilling phase can cost up to $30 million and has historically had a success rate of only about 60%.” However, investors and lenders are becoming more willing to finance exploratory drilling for geothermal energy as risks decrease through ongoing innovation and technology development.
Recent financing and development activity reflect this shift. For example, on April 16, 2026, Zanskar, an AI-native geothermal energy company, announced a $40 million financing deal following a $30 million Series B financing round in 2024 and a $115 million Series C financing round in January 2026. Just a few days before announcing the $40 million financing deal, Zanskar announced, a Geothermal Exploration, Offtake and Development Engagement (“GEODE”) agreement with California Community Power to locate new utility-sale geothermal resources across California.
Public investment is reinforcing this trend. The U.S. Department of Energy (“DOE”) announced multiple funding initiatives in 2026 aimed at accelerating advanced geothermal technologies. These include a $171.5 million funding opportunity for next‑generation geothermal field‑scale tests, up to $69 million for technologies that integrate critical mineral production with geothermal systems, and a $14 million enhanced geothermal system (“EGS”) demonstration project. Collectively, these programs signal a sustained federal commitment to advancing geothermal technologies.
Competition will likely increase with increasing available capital, and companies competing for financing will likely continue to innovate and develop technologies to give them an edge. As a result, the industry will likely shift further toward proprietary capabilities such as AI‑assisted exploration, advanced drilling workflows, engineered reservoirs, and closed‑loop systems, that enable predictable outcomes across diverse geologies. In this environment, those who invest early in defensible IP positions will be better aligned with the direction of geothermal growth. Accordingly, as the next development cycle accelerates, those who do not invest in defensible IP positions may find that access to future financing and development opportunities will increasingly depend on who owns the underlying innovation.
