Fusion vs Natural Gas
Gas is firm and flexible but emits CO₂ and methane and rides volatile fuel markets. Fusion offers the same firmness and flexibility with zero operating emissions and stable fuel.
- Both
- Firm, dispatchable, flexible
- Gas
- CO₂ + methane leakage; volatile fuel price
- Fusion
- Zero operating CO₂; stable, abundant fuel
- Role
- Replace gas firmness cleanly
Natural gas is the workhorse of modern firm power — dispatchable, flexible, and quick to ramp — which is exactly why it's the hardest fossil generator to displace. But it emits CO₂ when burned, leaks methane (a potent greenhouse gas) across its supply chain, and exposes operators to volatile fuel prices.
| Dimension | Fusion / Natural gas |
|---|---|
| Firmness & flexibility | Firm, dispatchable / firm, fast-ramping |
| Operating CO₂ | Zero / significant |
| Methane leakage | None / a major upstream issue |
| Fuel price risk | None (seawater + bred ³He) / volatile markets |
Fusion aims to provide the firm, flexible role gas plays today — without the emissions or the fuel-price exposure. Replacing gas firmness cleanly is one of the most valuable things a firm zero-carbon source can do for a decarbonizing grid. See fusion & decarbonization.
