Don't think so. As I recall scrubbers are for dealing with SOx emissions. While there are some new technologies for lowering the amount of fly ash, the bottom ash is still going to be a problem. Can't fix that with a scrubber. That's why they store it in giant ash ponds. Ash ponds full of toxic metals that, when they leak into nearby rivers, cause all manner of environmental disasters. Like

Not a fan but realize it is one of the scalable greener energy
Chernobyl, TMI, Fukushima, SL-1, Santa Susana Field Laboratory, the list goes on. That's probably why.
I'm actually kind of a fan of the newer technologies that are more "safe" or passively safe. I think there's a place for it, but it isn't going to be an easy sell. It will, ultimately be one of the few options we actually have that we can easily and quickly scale and use.
