$35M Investment Brings Superhot Geothermal Power Closer

Imagine drilling so deep into the Earth that you reach temperatures hot enough to melt rock, then turning that extreme heat into clean, reliable electricity around the clock.

That vision moved significantly closer this week as Nabors Industries invested $35 million in Quaise Energy, a company developing revolutionary drilling technology using millimeter-wave energy instead of traditional drill bits. The investment is part of Quaise's Series B funding round and signals serious momentum for geothermal energy's next frontier.

Quaise's approach sounds like science fiction but it's already being field-tested. The company combines conventional drilling with high-powered millimeter-wave technology that essentially vaporizes rock using energy beams transmitted down a special tube called a waveguide. This hybrid method can reach depths and temperatures impossible with standard drilling equipment, unlocking vast geothermal resources that currently sit untouched miles beneath our feet.

Right now in Oregon, a Nabors drilling rig is working on Project Obsidian, which aims to become the first commercial superhot geothermal system in the world. The first phase targets 50 megawatts of reliable power, enough to supply tens of thousands of homes. Future phases could add up to one gigawatt of additional capacity, powering entire cities with heat from the Earth's core.

What makes this partnership particularly powerful is the combination of innovation and experience. Quaise brings cutting-edge physics and engineering, while Nabors contributes decades of drilling expertise, a global network, and proven field execution capabilities. Together, they're turning laboratory concepts into commercial reality.

The Ripple Effect goes far beyond one power plant. Geothermal energy provides baseload power that works 24/7 regardless of weather, unlike solar or wind. By accessing deeper, hotter resources almost anywhere on Earth, superhot geothermal could transform the clean energy landscape. Countries without traditional geothermal hot spots could tap this resource. Retired fossil fuel workers could apply their drilling skills to climate solutions. And communities could gain energy independence with locally sourced, completely clean power that never runs out.

The investment also secured Nabors an exclusive arrangement to provide drilling services for Quaise's projects, creating a clear pathway for both companies to grow together as the technology scales. They're already planning collaborations on rig engineering, automation, and global project development.

Carlos Araque, Quaise's CEO, called Nabors' increased commitment "a strong endorsement of our technology and growth strategy." Anthony Petrello, Nabors' CEO, sees it as "one of the most compelling opportunities in geothermal energy," noting how perfectly the innovation aligns with his company's core strengths.

The Earth's heat represents an essentially limitless energy source, and we're finally developing tools sophisticated enough to access it at scale.
