The Fuel Supply Chain End To End
From ocean water to fusion and back to bred fuel, the complete chain has few steps and no extractive bottleneck.
The whole chain in view
Seen end to end, the fusion fuel supply is short. Water is separated to yield deuterium. Deuterium and bred tritium fuse in the breeder (Hyperion). Neutrons breed fresh tritium in the lithium blanket, which is recovered and returned. Surplus tritium decays into helium-3, which can fuel the burner (Aegis / MetroVolt) or serve other uses.
No extractive bottleneck
Unlike conventional chains, no step in this sequence depends on a mine, a well, or a region-specific deposit. The only external inputs are water and lithium, both abundant. Everything else is generated inside the plant. This is why the chain is resilient and why it scales without securing new resources.
- Step 1: separate deuterium from water
- Step 2: fuse deuterium with bred tritium
- Step 3: breed and recover tritium in the blanket
- Step 4: harvest helium-3 from decayed surplus tritium
Two machines, one chain
The breeder makes the fuel; the burner uses the helium-3 it produces. Together they form a coherent supply picture rather than two isolated fuel demands. See the breeder-burner fuel link and the closed fuel cycle.
Short chain, no chokepoints
Laid out end to end, the fusion fuel chain is short and free of the chokepoints that define conventional supply: no mine, no well, no region-specific deposit, no refining monopoly. Its only external inputs are water and lithium, both abundant and dispersed, and its central steps happen inside the plant. Shortness and the absence of bottlenecks are what make the chain resilient.
