Fusion energy companies Type One Energy and ExoFusion have announced an extension of their partnership aimed at optimizing stellarator designs, with a specific focus on maximizing plasma confinement. The collaboration, which builds on existing work, is expected to reduce the timeline to Commercially Viable Fusion (CVF) by improving the edge region of the plasma. Both companies view this as a critical step toward practical fusion power.
ExoFusion, based in Austin, Texas, specializes in physics and technologies for confinement and novel first-wall materials. The company has received grants from ARPA-E, SCIDAC, FIRE, INFUSE, and other programs. Type One Energy, headquartered in Bellevue, Washington, is a venture-backed stellarator developer that applies advanced manufacturing, computational physics, and high-field superconducting magnets. Its FusionDirect program aims to build a fusion power plant within the coming decade.
The extended partnership leverages ExoFusion’s expertise and intellectual property alongside Type One Energy’s leadership in stellarator engineering and science. According to the announcement, this combination serves as a strong accelerant to achieving commercially viable fusion. The companies have not disclosed specific financial terms or milestones for the collaboration.
Stellarators are a type of fusion device that uses twisted magnetic fields to confine plasma, offering inherent stability but requiring precise engineering. Optimizing the edge region of the plasma is crucial because it affects overall confinement and the performance of the fusion reaction. By improving confinement, the companies aim to increase the efficiency and reduce the cost of future fusion power plants.
The partnership reflects a broader trend in the fusion industry where companies are collaborating on specific technical challenges rather than competing across all fronts. ExoFusion works across multiple device types and fuel cycles, while Type One Energy focuses exclusively on stellarators. Their combined efforts could help address key physics and engineering hurdles that have historically slowed fusion development.
