Quaise Energy develops a drilling platform that combines conventional rotary rigs with high-power millimeter waves to vaporize rock. This technology enables wells to reach depths and temperatures that exceed the capabilities of mechanical bits, targeting deep superhot rock for baseload power.

The company serves the global energy market by leveraging existing oil and gas workforce and infrastructure to deploy superhot geothermal plants. It competes with traditional geothermal energy and fossil-fuel baseload power, positioning on scalability and minimal land use through projects like Project Obsidian.
