Thing is that back in the old days of Tomorrows World there were stories of

There was a lot of talk about fluidised bed combustion. But I think
that was mainly aimed at increased efficiency and the ability to
remove sulphur dioxide because acid rain was the big environmental
worry then.

Use of metal oxide burning reactions produces an almost pure CO2 (Nox
and nitrogen free) exhaust but even then you have to scrub for S02 and
of course CO2 if you actually give a damn.
