We start with the fuel.
Kronos Fusion Energy is a breeder-first fusion company. We make the fuel and the strategic materials the U.S. can't source at scale — then burn the fuel for firm, carbon-free power.
Two machines, in the open.
The breeder
HYPERION makes helium-3, tritium, and a 14 MeV neutron flux — a domestic source for materials America can finally make at home.
The burner
A low-neutron D–³He generator, built as Aegis (defense) and MetroVolt (data centers), turns that fuel into firm power.
In the open
Peer-reviewed papers, open code and data, and a live simulation anyone can run. Credibility you can reproduce.
Sixty years of fusion.
The integrated machines are not yet built — construction of the breeder (Hyperion) begins Q2 2027 with the first unit online — first tritium — targeted ~2030 — and we say exactly what isn't proven yet.
Open by design.
