Tranquillion is pleased to announce our investment in Zanskar Geothermal’s $115 million Series C, alongside Spring Lane Capital, Obvious Ventures, Union Square Ventures, Lowercarbon Capital, All Aboard Fund, and other leading climate investors. Our mission is to address the ‘missing middle’ in climate technology, and to back the next wave of clean energy technologies ready to scale. Zanskar is poised to transform geothermal from a niche resource into a major source of firm, clean power.
Zanskar has developed an AI-native exploration platform that has collapsed geothermal discovery timelines and costs by an order of magnitude. Their turnaround of Lightning Dock in New Mexico – an abandoned project now operating as the most productive pumped geothermal well in the United States – demonstrates that the company can find value where others could not. The team has since proven this model repeatedly, uncovering previously unknown resources across Nevada and assembling a substantial land position at a fraction of market cost. While focused on conventional geothermal today, Zanskar’s technology-agnostic platform positions it to capitalize on enhanced, advanced, and supercritical geothermal systems as they mature.
Geothermal delivers what the grid desperately needs: firm, clean baseload power that runs 24/7. As hyperscalers race to power AI infrastructure with carbon-free electricity, Zanskar is positioned to deliver much-needed additional capacity by decade’s end, proving that AI can help solve its own energy problem. We believe the combination of an exceptional team, technology-driven discovery, asset-backed downside protection, and exponential demand growth makes this precisely the kind of opportunity our capital structure was designed to pursue.
