Geo-Sequestration Revisited: "The PDF summary report (which is all that's currently available) starts out by describing in detail the currently available processes for carbon capture and storage; the document doesn't address biological sequestration options, as they are largely useful for reduction of existing concentrations, not reduction of new emissions. The three broad families of capture systems -- 'post-combustion,' 'pre-combustion,' and 'oxyfuel' -- are described, and discussions of costs, geographic requirements for storage, and risks (from the environmental to the legal) close out the document.

"The summary report runs a brief 25 pages, and it makes for sobering reading. Under best case scenarios, carbon capture and storage wouldn't make a significant difference in CO2 levels until the mid-point of this century; in addition, the current available sequestration options all pose significant challenges, including the possibility of actually exacerbating the global environmental situation rather than ameliorating it."

Industry demands will probably see interminable talk about geo-sequestration, but (like the nuclear lobby) it is simply a distraction and a diversion. Research, publicity, time and energy spent on these two is not being spent on the real answers - clean, renewable energy.
