My point was that clean coal can mean a lot of things and sometimes making one part of a product lifecycle "green" just passes the problem down the supply chain.
In this case, scrubbing the flue gasses and recycling the coal ash resulted in toxic drywall. This isn't to say all drywall is toxic but it illustrates one illusion of something being clean or green.
This was a boondoggle near my hometown: sttps://en.m.wikipedia.org/wiki/Healy_Clean_Coal_Project
Sheetrock/gypsum board is another byproduct: https://www.buildinggreen.com/primer/synthetic-gypsum
There was a wave of flue gas gypsum emitting acidic gasses around 2009, eating through copper plumbing and wiring. This was in Florida.
CO2 still has to go somewhere. Carbonation, industrial gasses, into the ground, or into the air.
I'm skeptical of clean or green in any product name. It's more about marketing.
