K-DEMO
K-DEMO is a tokamak fusion project run by Korea Institute of Fusion Energy in South Korea. It is planned. Like every fusion device built so far, it has produced no net electricity.
No hardware. Design phase.
Intended as the first plant to contribute fusion power to a grid, with an operational phase projected between 2037 and 2050.

Other tokamak projects
Fusion needs tritium, and the world's civilian stock comes mostly from CANDU fission reactors. See the fusion overview.
K-DEMO in context
14 of the 24 fusion projects on record use the tokamak approach: 7 operating, 3 under construction, 3 planned and 1 closed.
It lists a target date of 2037, 11 years from now; of the 7 projects that list one, 5 list an earlier year. A target date is the project's own aim, not a forecast.
| Measure | K-DEMO | Median of all projects | Standing |
|---|---|---|---|
| Target date | 2037 | 2028 | 6 of 7 (earliest first) |
Worked out from the entries on this site only, so a figure compares K-DEMO 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.
