When will fusion energy be commercially available?
For Kronos: a prototype targeted for 2030, and a commercial fleet in 2036 and beyond.
Kronos publishes a dated, gated plan: open the physics in 2026, build a prototype targeted for 2030, and field a commercial burner fleet 2036 and beyond. The integrated machines are not yet built.
Open physics
Peer-review papers, open data, a live simulation — the design point solved and reproducible.
Prototype
Breeder physics on hardware; confinement and blanket gates retired step by step.
Fleet
The commercial generators — Aegis and MetroVolt — at scale.
