What ever happened to coal gassification? Or scrubbers, years back in another life I worked for Combustion Engineering, we used to build big (initially) coal fired plants for the pulp and paper companies, Every single one had scrubbers just ahead of the chimneys. They would start up on coal but when it was available they would burn black liquor, something that came from the paper making process that was combustible.
