Major Funding Round and Future Plans
Zanskar, a geothermal developer based in the United States, has successfully raised $115 million in a Series C funding round aimed at expanding its artificial intelligence (AI)-based geothermal discovery platform. The funding, led by Spring Lane Capital, also saw participation from notable investors including Obvious Ventures, Union Square Ventures, and Lowercarbon Capital. This latest round brings Zanskar's total equity funding to $180 million. The company plans to utilize the new capital to enhance its geothermal exploration capabilities, scale drilling operations, and initiate the construction of geothermal power plants at identified sites within its multi-gigawatt development pipeline. Zanskar anticipates that its initial projects will begin generating electricity before 2030.
Innovative Approach to Geothermal Discovery
Zanskar's strategy involves leveraging AI to streamline the discovery and development of geothermal resources. The company employs a two-stage AI methodology: first, it utilizes supervised machine learning models to analyze historical data and identify promising geothermal sites, many of which lack visible surface indicators like hot springs. Approximately 95% of geothermal systems do not exhibit such surface signs, making traditional exploration methods less effective. Following the identification of potential sites, Zanskar's teams validate these discoveries through field assessments. The company also employs Bayesian evidential learning (BEL) to model subsurface conditions and optimize drilling locations.
Achievements and Market Potential
Zanskar's innovative approach has already yielded significant results. The company has successfully revived the Lightning Dock geothermal power plant in New Mexico and discovered two new geothermal sites with a combined potential exceeding 100 megawatts. Zanskar's CEO, Carl Hoiland, asserts that the conventional geothermal capacity in the U.S. has been underestimated, suggesting that the actual potential could reach up to 1 terawatt, significantly higher than the Department of Energy's projection of 60 gigawatts by 2050. This discrepancy highlights the potential for geothermal energy to play a crucial role in meeting the growing demand for clean, reliable power.
Industry Response and Future Outlook
The funding round reflects a growing investor confidence in geothermal energy as a viable source of low-carbon power amid increasing electricity demand from various sectors, including data centers. Zanskar's CTO, Joel Edwards, emphasized the urgency of rapid development, stating, “It’s the Wild West... who can build the fastest and at a reasonable cost is going to win this game.” The company is actively recruiting engineers and finance professionals to support its expansion efforts, aiming to transition from exploration to the construction and operation of geothermal power plants.
Criticism and Challenges
Despite the optimism surrounding Zanskar's approach, the geothermal sector faces challenges, including high exploration costs and lengthy development timelines. Critics point out that while Zanskar's AI-driven methods show promise, the company has yet to fully address the risks associated with geothermal resource discovery and development.
