If they did manage to find a good sequestration mechanism that could be used near coal fields, it might provide some value - but percentage wise, not very much.

James, yes it is likely to be used to some degree in the future, but it's p*ssing in the wind as far as I can tell, to be frank, and as to clean coal...yes, great cut local particular and sulfur pollution, but it cannot be touted as clean, it's anything but, getting it out of the ground uses energy, cleaning it up uses energy, transporting it uses energy, burning it produces CO2 which ever way you look at it.

One other issue that has popped up here in the US is that companies are touting "clean coal" technology. This is an advanced method of removing particulates and harmful gasses from the burned byproduct (a good thing), but it does not remove the CO2. I get the impression that distinction isn't always clear to some in the general public.

Seems like the water would react and form carbonic acid. Perhaps I don't understand the logistics, but that seems like it would disrupt the ecosystem surrounding the CO2 pit.
