As I understand it, 'clean coal' technology has been around for a decade or more but the demonization of the industry by a combination of Democrats, a sycophantic scientific community dependent of grants for their existence, and a supportive media have made it all but impossible to persuade detractors even with solid scientific evidence.
Let's be clear here though - this has nothing to do with concern for the environment, it is all about the money - follow the money. Bill Clinton designated one of the largest coal reserves on the planet into a National Park after receiving HUGE donations from the group that owned the second largest reserve (in Indonesia, I believe). Barack Obama directed hundreds of millions, if not billions, to start up solar companies (started up by his cronies), that went bankrupt a few short years later with absolutely ZERO accounting for where the money went. Hillary will follow the same business model. The Clintons do, and the Obamas will shortly, live the lifestyles of billionaires and most of the American public will be too complacent to be any the wiser on what has been done to them.
