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.

Thea Energy is a New Jersey-based fusion power company commercializing a planar-coil stellarator architecture, using arrays of mass-manufacturable superconducting magnets and software-defined controls in place of precision-machined 3D coils. Spun out of Princeton University and Princeton Plasma Physics Laboratory in 2022, it is an awardee of the US Department of Energy's Milestone-Based Fusion Development Program and is building the Eos integrated stellarator en route to its first commercial Helios power plant.
