I do not know as a fact that clean coal is being promoted more now, than before. I have no inside industry information on this subject.
I've included a number of links on the "clean coal technology", with the first two links, spoofing the clean coal ads. So the clean coal ads have had a backlash on the internet.
All companies in the coal industry have public relations departments, which promote environmentally safe practices and advances in technology to minimize pollution.
Also, there are non-profit organizations, such as the American Coalition of Clean Coal Electricity, funded by energy companies. The list of the companies that are members is provided on their website. (see related link)
If there is an increase in clean coal technology promotion (and I don't know if this is true), it may be due in part to the numerous efforts worldwide to curb carbon emissions based on climate change concerns.
From the perspective of a coal company, there is always concern that there will be more regulatory action, making it more expensive to generate electricity.

clean coal is not renewable
There isn't a single individual who can be credited with discovering the use of clean coal. Clean coal technologies have evolved over time through the efforts of numerous scientists, engineers, and researchers working to reduce the environmental impact of coal-fired power plants.
Clean coal technologies are still expensive to implement and may not reduce emissions as much as expected. There are also concerns about the disposal of byproducts such as ash and CO2 storage. Additionally, mining and transporting coal still have environmental impacts.
There is no such thing as "clean coal". People who talk about it, such as in TV commercials, are just trying to fool you with a lot of nonsense. Burning coal always produces carbon dioxide, sulfur dioxide, nitrogen dioxide, sulfur trioxide, and carbon monoxide, and those are all dangerous pollutatants and generators of acid rain. In addition, most of the smokestack gases listed above are strong greenhouse gases and they trap head in the atmosphere. That contributes to climate change, thunderstorms, tornadoes, hurricanes, and the enlargement of deserts.

A wall of coal that's being worked or being prepared to work is a coal wall face.
Coal. Anthracite is a very hard very clean burning metamorphic type of coal.
It is very important to use clean coal technology. The pollutants from burning coal causes health problems as well as environmental problems. The clean coal technology cuts back on these pollutants and provides a cheap form of energy.
Because coal absorbs the coal molecules and that makes the water clean.
Water vapor is not a byproduct of burning coal that must be restricted in order to produce clean coal. Other byproducts such as carbon dioxide, sulfur dioxide, nitrogen oxides, and particulate matter must be limited to achieve cleaner coal production.
