Infinity Two
Infinity Two is a stellarator fusion project run by Type One Energy in United States. It is planned. Like every fusion device built so far, it has produced no net electricity.
No hardware. Construction targeted from 2028, at a TVA site in Tennessee.
A 400 MWe commercial stellarator concept, the first serious private attempt at the geometry.

Fusion needs tritium, and the world's civilian stock comes mostly from CANDU fission reactors. See the fusion overview.
Infinity Two in context
3 of the 24 fusion projects on record use the stellarator approach: 2 operating, 0 under construction, 1 planned.
It lists a target date of 2028, 2 years from now; of the 7 projects that list one, 2 list an earlier year. A target date is the project's own aim, not a forecast.
Its stated fusion power target is 400 MW, 2nd of the 6 projects that state one (median 300 MW).
| Measure | Infinity Two | Median of all projects | Standing |
|---|---|---|---|
| Target date | 2028 | 2028 | 3 of 7 (earliest first) |
| Fusion power target (MW) | 400 | 300 | 2 of 6 |
Worked out from the entries on this site only, so a figure compares Infinity Two with what is recorded here, not with everything that exists. An entry with no value for a measure is left out of that measure's ranking and median.
