About

Quaise Energy is developing a radically new ultra-deep drilling platform that uses high-power millimeter waves derived from breakthrough fusion research at MIT's Plasma Science and Fusion Center to vaporize rock and reach geothermal depths of 3-20 km at temperatures of 300-500 degrees Celsius. Unlike conventional drilling, Quaise's gyrotron-powered system can repurpose existing fossil-fuel power station infrastructure to convert to superhot geothermal, enabling a faster and more equitable energy transition. The company was founded in 2018 and has raised over $21 million to advance its technology toward commercial field trials.
