Clean coal – as in burning and capturing the CO2 – is an idea being floated. There are obvious problems (apart from anything else, the capture and storage costs extra energy and so burns even more coal…), and AFAIK only a few pilot schemes exist. So the story that a commercial-scale plant was being built was interesting. Desmogblog commented on it under the heading “The Expensive Myth of Clean Coal” (and just in case youre not inclined to follow the link, there’s an extra bonus of a gratuitous tart-in-a-bikini awaiting you). It looks to be a coal-industry boondoggle: for a $1.8B plant there is a $1B subsidy, which according to DSB makes it about 2* as expensive as wind and about as expensive as solar. I wonder how much subsidy the US solar industry gets?
