I'm no fan of coal, but to be fair "integrated gasification combined cycle" plants [1] are way cleaner than conventional coal plants without violating laws of thermodynamics. You can drastically reduce emissions of e.g. heavy metals, sulphur oxides, carbon monoxide, and particulate matter, while being amenable to pre-combustion carbon capture.

This is largely theoretical. The Kemper demo plant is a disaster in terms of massive cost overruns, many years of delays, and inconsequential net energy production. They ultimately abandoned the project.
