Quaise develops drilling technology that uses millimeter-wave energy and conventional drilling methods to access deep geothermal heat for electricity generation. The company designs and tests systems that vaporize rock to reach greater depths than conventional drilling techniques, enabling access to superhot geothermal resources. Its approach combines rotary drilling with high-power millimeter waves to create deep boreholes for geothermal energy production. Quaise also focuses on adapting existing power plant infrastructure to support geothermal energy generation using its drilling technology.
