Western writes, "With climate change making conventional uses of coal less palatable, the two plants could provide a relatively clean future use for it." And later, "The process gives off carbon dioxide, but in a form that is easy to re-use, although plenty of questions remain about carbon dioxide transport and storage."
It seems as if there is an attempt to claim that this technology will help with the big problems of climate change. In fact, it seems to me as if this form of energy production is likely to produce more carbon dioxide molecules per watt of energy than other fossil fuels, and as such is likely to be worse for the problem of climate change. However, it seems as if it is likely to help with the problem of low-level atmospheric unhealthful emissions from coal plants.
Furthermore, there are not "questions about carbon dioxide transport and storage." There are only "pie in the sky" thoughts about storage and removal.
