A group of Ohio State scientists has developed a reactor that chemically burns coal, creating energy while capturing almost all the CO2 generated. You have to go all the way to the bottom of the article before they mention how expensive it is. "Beating" a 35% increase still means it's much more expensive than existing technologies. But then, that's always been the problem with almost all green power generation. Still, that's just engineering. If they can pull the costs down to the point it's competitive, I'm all for it.
