Introducing Project Obsidian: the world’s first superhot geothermal power plant.
Right now in Central Oregon, our team is pushing geothermal beyond its limits and into a whole new era.
For the first time, we’re building a plant designed to generate electricity where Earth’s natural heat is most powerful: 300–500°C. At those temperatures, a single well can deliver 10–100x more power than all other forms of geothermal.
Project Obsidian is the birthplace of gigawatt-scale geothermal and a new chapter in human innovation.
Because when energy is high-density, always-on, low-cost, and zero-carbon, it doesn’t just power the grid; it reshapes economies. It strengthens energy security and brings reliable power within reach for communities everywhere.
Project Obsidian, at a glance:
- Phase I: 50 MW
- Phase II: 250 MW
- Phase III: 1+ GW
- Zero waste
- Zero fuel
- Zero emissions
Humans have used geothermal for thousands of years, but mostly where nature makes it easy: hot springs and rare geologic hotspots. Our key technology breaks that boundary by going hotter and deeper than ever before.
Millimeter wave drilling is the solution: high-power microwaves that ablate rock with zero contact. Project Obsidian will be the first commercial deployment of millimeter wave drilling, unlocking a future where geothermal can expand east of the Mississippi and beyond the global Ring of Fire, bringing superhot geothermal within reach of more than 90% of humanity.
Obsidian is just the beginning; it’s the best-studied, most economically viable location in the United States to prove a whole new scale of clean power using Earth’s natural heat.
This is superhot geothermal: energy, perfected. Learn more about Project Obsidian here.
