Quaise Energy — Millimeter wave drilling for deep geothermal wells
Quaise develops millimeter wave drilling systems for deep geothermal heat access. Our technology is the only approach in the world with the potential to build geothermal wells at unprecedented depths and temperatures. By targeting depths up to 20 kilometers and temperatures up to 500 degrees Celsius, we will have the ability to build clean electric generation and heat distribution plants within a short distance of every major population and industrial center on the planet, at a fraction of the footprint of other renewables. And by scaling through the established supply base of the fossil fuel industry, we will be able to achieve the terawatt-level annual deployments that will be required to successfully decarbonize our global energy system.
