Kronos Fusion Energy · The Roadmap

Proven today. Building in 2027. Powering the fleet in the 2030s.

Kronos is a company on a schedule. The physics is de-risked and the machines are drawn — what comes next is steel in the ground and fuel in the loop.

2026 · NOWComplete

De-risked and drawn

Every binding physics claim validated and reproduced. Three machines locked to a frozen design point. Engineering drawings complete, the supply chain mapped, and the core IP filed. The hard science is behind us.

Q2 2027Next

Break ground on the first breeder

Construction begins on the first Hyperion — the fuel foundry. Long-lead components on order, site works underway, the first magnets in fabrication.

2030 – 2031

First tritium

The breeder comes alive and makes its own fuel — and a surplus. Medical-isotope and neutron-services production come online, turning the machine into revenue from its earliest operation.

2032

Burner power demonstration

Aegis and MetroVolt — the burners — demonstrate firm, dispatchable output, fueled by the breeder's helium-3. The two-machine architecture proven end to end.

2036

First commercial fleet units

Breeders and burners deploying together — isotopes and firm power delivered under contract. The first units of a fleet built to scale.

2040s → 2050

Fleet at scale

A growing fleet of breeders feeding a much larger fleet of burners — powering cities and data centers, supplying the world's isotopes, and anchoring an Earth–Moon helium-3 economy.

Where we are right now: everything before the 2027 ground-break is done. See what we've proven or explore the physics gallery.
