Fusion's Carbon Footprint
Fusion emits no carbon while running. Kronos points the real question at construction, where it belongs.
- Operational CO2
- Zero
- Lifecycle
- Embodied carbon in construction
A fusion plant emits no CO&sub2; in operation — its fuel is hydrogen isotopes. The meaningful lifecycle question is embodied carbon in materials and construction, common to all built infrastructure, which Kronos includes in its environmental screening rather than claiming a free pass.
Common questions
Not in operation — the reaction produces helium, not carbon dioxide. The footprint is in construction materials (steel, concrete, magnets), like any large clean-energy plant.
Its lifecycle emissions are dominated by one-time construction, spread over decades of firm output — in the same low range as other low-carbon generation, which Kronos assesses rather than asserts.
