So, what you’ll want to do, then, is to use cheap electricity to bring down the price of CO2.
Then, sequester as much carbon as you like, via biomass. Carbon recovery by photosynthesis dramatically increases when plants are fed a rich supply of nutrients including high CO2 concentration.

However, this bio-recovery process will probably appear, first, via pumping the effluent from coal plants directly to algae tanks.

Wouldn’t it be a lot simpler and cheaper just to shut down the coal powered plant and use fusion to generate the electricity from the start?
