Type One Energy (T1E) is a fusion machine developer focusing on the stellarator path to fusion energy. Their approach is to build stellarators using high-temperature superconductors (HTS) with coils that are non-planar. Their plan is to first build Infinity One, a stellarator with the goals of demonstrating their non-planar coil stellarator architecture and other plasma performance metrics. Beyond Infinity One, they plan to build an electricity generating pilot plant, Infinity Two.

Infinity One

Infinity One image
Description

Type One Energy is working with the Tennessee Valley Authority (TVA) and Oak Ridge National Laboratory (ORNL) to develop a stellarator to verify Type One Energy's Fusion Power Plant (FPP) concept. The device is currently planned to be built at the TVA's Bull Run retired coal power plant.

The results of Infinity One will inform Type One Energy's Infinity Two project.

Infinity Two

Description

Type One Energy is working with the Tennessee Valley Authority (TVA) to develop a 350 MWe fusion power plant that is currently planned to begin operations by the mid 2030s.

As of early 2025, Type One Energy has partnered with Commonwealth Fusion Systems (CFS) whereby CFS has granted Type One Energy access to use their high-temperature superconducting (HTS) cable technology. This arrangement will help support Type One Energy's development of the Infinity Two's stellarator magnet system.
