Problem
The global demand for electricity continues to rise while conventional energy sources contribute to climate change, geopolitical instability, and waste management challenges. Scalable, safe, and sustainable baseload power remains elusive, and intermittent renewables alone cannot reliably meet base load requirements.
Solution
Type One Energy designs and deploys stellarator-based fusion power plants that convert fusion energy into steady-state, emission-free baseload electricity. The company leverages high-temperature superconducting (HTS) magnets, exascale supercomputing, and modern AI-driven optimization to create a magnetic confinement system that keeps plasma stable without the disruptions seen in other fusion approaches. Type One Energy's FusionDirect program pursues a direct path to commercialization, and the company is currently building Infinity One, an engineering verification stellarator, and Infinity Two, a 400 MWe commercial fusion power plant, in partnership with the Tennessee Valley Authority at the Bull Run Energy Complex. Its technology builds on decades of peer-reviewed stellarator research, culminating in a physics basis published in the Journal of Plasma Physics.
Target Audience
Primary customers are utility companies and energy producers seeking carbon-free, firm baseload power to supplement renewables and retire fossil fuel plants.
Features
- Optimized stellarator design achieves steady-state plasma operation, avoiding the instabilities of pulsed tokamak designs
- Non-planar high-temperature superconducting (HTS) magnets enable compact, high-field confinement and reduce overall plant size
- Advanced manufacturing techniques lower construction costs and accelerate deployment timelines compared to traditional fusion approaches
- Peer-reviewed physics basis, described by the Journal of Plasma Physics editors as "the gold standard," supports the Infinity Two design
- Infinity One serves as both an engineering verification platform and the world's first workforce training facility for commercial fusion
- Partnership with TVA includes submission of the first-ever U.S. license application for a commercial fusion machine
