About
Quaise Energy is an energy technology company on a mission to unlock the planet's largest untapped clean energy source: deep geothermal heat. Traditional geothermal is limited to volcanic hotspots, but Quaise's breakthrough millimeter wave drilling platform vaporizes boreholes through rock using high-power gyrotron beams — the same technology developed for nuclear fusion research — enabling access to superhot geothermal resources at depths of 3–20 km virtually anywhere on Earth. Once conventional rotary drilling reaches basement rock, the system switches to millimeter waves transmitted via standard oil-and-gas tubing acting as a waveguide. A purge gas carries vaporized rock back to the surface, leaving a clean, vitrified borehole. At depths of 20 km, temperatures can reach 300–500°C, unlocking power densities comparable to fossil fuels. Quaise's approach is designed for speed and scale: it reuses the established workforce, supply chains, and regulatory frameworks of the oil and gas industry, dramatically lowering the cost and time to deploy geothermal power globally. Their flagship Project Obsidian in Central Oregon targets an initial 50 MW of capacity, expandable to 250 MW, with commercial operation planned by 2030. Long-term, Quaise envisions multi-terawatt geothermal energy as a cornerstone of a net-zero world by 2050 — delivering equitable, inexhaustible clean power to every nation.
Key Features
- Millimeter Wave Drilling: Gyrotron-powered beams vaporize rock to drill boreholes far beyond the reach of conventional rotary equipment, enabling depths up to 20 km.
- Superhot Geothermal Access: Reaches temperatures of 300–500°C at depth, unlocking power densities comparable to fossil fuels and making geothermal viable globally.
- Reuse of Fossil Fuel Infrastructure: Leverages existing oil and gas workforce, supply chains, and regulatory frameworks to accelerate deployment without building from scratch.
- Project Obsidian: First commercial-scale superhot geothermal project in Central Oregon, targeting 50 MW initial capacity expandable to 250 MW by 2030.
- Global Scalability: Deep geothermal heat is accessible anywhere on Earth at sufficient depth, enabling energy independence for every nation and a path to net-zero by 2050.
Use Cases
- Providing always-on baseload clean electricity to power grids in regions lacking traditional geothermal resources.
- Repurposing decommissioned fossil fuel plants by replacing combustion with deep geothermal heat sources.
- Supplying large-scale industrial heat for manufacturing, hydrogen production, and other energy-intensive processes.
- Enabling energy independence for nations that currently rely on imported fossil fuels by tapping local geothermal resources.
- Supporting net-zero decarbonization strategies by delivering multi-terawatt renewable power with no intermittency.
Pros
- Always-On Clean Power: Unlike solar or wind, deep geothermal provides 24/7 baseload electricity with no intermittency issues.
- Globally Universal: By drilling deep enough, superhot geothermal resources are available everywhere on Earth, not just volcanic regions.
- Built on Proven Infrastructure: Uses established oil and gas drilling practices and workforce, drastically reducing technology risk and deployment timelines.
- Massive Scale Potential: Designed to deliver multi-terawatt energy capacity, positioning geothermal as a primary pillar of global decarbonization.
Cons
- Early-Stage Technology: Millimeter wave drilling at commercial scale has not yet been fully demonstrated; Project Obsidian is the first proof-of-concept deployment.
- Long Development Timeline: Commercial operation is not expected until 2030, requiring sustained investment and regulatory approval over many years.
- Capital Intensive: Deep drilling projects require substantial upfront capital for equipment, site development, and grid interconnection.
Frequently Asked Questions
What is millimeter wave drilling?
Millimeter wave drilling uses high-power beams from a gyrotron — a device originally developed for nuclear fusion research — to vaporize rock. The waves are transmitted down a borehole via standard oil-and-gas tubing acting as a waveguide, enabling drilling to depths far beyond conventional mechanical methods.
Why is superhot geothermal better than conventional geothermal?
Superhot geothermal (300–500°C) has far greater power density than conventional geothermal (typically under 150°C), allowing it to generate electricity as efficiently as fossil fuel plants and to repurpose existing fossil-fuel infrastructure for clean energy.
What is Project Obsidian?
Project Obsidian is Quaise Energy's flagship commercial demonstration project located in Central Oregon. It aims to deliver an initial 50 MW of always-on geothermal power, expandable to 250 MW, with commercial operation targeted by 2030.
Where can Quaise's technology be deployed?
Because Quaise drills deep enough (up to 20 km) to reach superhot rock temperatures anywhere on Earth, the technology is not limited to volcanic hotspots. It can be deployed near any population or industrial center globally.
How does Quaise leverage the fossil fuel industry?
Quaise's drilling platform uses standard oil-and-gas tubing, conventional rotary rigs for the upper portion of each well, and the existing trained workforce and supply chains of the fossil fuel sector — enabling faster, lower-cost deployment compared to building new infrastructure from scratch.
