Fusion vs Coal

Both are firm, always-on power — but coal emits CO₂ and pollution and depends on mining, while fusion is clean and runs on seawater-derived fuel.

Both

Firm, dispatchable baseload

Coal

High CO₂, air pollution, mined fuel

Fusion

Zero operating CO₂, no pollution

Role

Fusion can replace retiring coal baseload

Coal is the classic firm baseload generator — reliable, always-on power — which is exactly the role a decarbonizing grid still needs filled. The problem is everything else about it: coal is among the most carbon-intensive and polluting ways to make electricity, and it depends on a continuous mined-fuel supply chain.

Fusion's promise is to deliver coal's firmness without its emissions — a direct, like-for-like replacement for the retiring fossil baseload that a clean grid must eventually shed. See fusion & decarbonization.
