A stellarator technology supplier

Type One’s approach uses a twisted magnetic confinement system to control plasma, supported by high-temperature superconducting magnets and computational design. Its Infinity One project is an engineering verification platform at the Tennessee Valley Authority’s Bull Run site.

Partnering with power producers

The company develops core fusion technology and equipment for utilities and other operators rather than building a business around selling electricity itself. Its commercialization strategy relies on partners for power-plant deployment.
