There are 2 things you forgot in this article, that make it entirely impossible to ever make "clean coal:" the "cradle" and the "grave."
The "cradle" part is that you have to get the coal out of the ground in the first place.
You mentioned swing states Ohio and Pennsylvania as two states with a lot of coal. Have you ever been there to see the coal mines , or in Kentucky or West Virginia, which are even harder hit? Try looking at www.mountainroadshow.com/ or www.ilovemountains.org/ to get an idea. These are organizations of the people who live there.
The "grave" is that CO2 has to be stored.There are 2 major issues here:
- In large quantities, CO2 lies below the oxygen of the atmosphere if it escapes. That means, that if a bubble of CO2 should escape, it could lie as a deadly blanket over the earth, asphyxiating all animal life (that includes people) in the area. This has already happened at least once, in Africa. See 1986: Hundreds gassed in Cameroon lake disaster.
- Not to mention the fact that we would need enormous secure cavity volume to contain all the CO2 that is produced.
Like nuclear, the "grave" part of the lifecycle hasn't really been solved yet, and it will prove extremely difficult. The "grave' could easily be not only the grave of CO2 or spent fuel, but of thousands of people (and other life!)
