I wasn't even discussing viability of the whole concept, but only the fact that there exists technology to capture and store CO2. Whether or not it is necessary to do so is a rather contentious subject.russ_watters said:What I'm saying is that their numbers don't imply viability for even much shorter timeframes. This is admittedly speculative, but if the storage is spread out evenly around the world and all of it is accessible, the numbers for the US look like this . . . .
It appears there are several small scale demonstration projects underway, with larger ones coming online in the next few years. It's a matter of economics - one starts small with low capital cost with the objective that the technology achieves what is expected, then scales up to larger systems. If the technology fails, then it's not applied on the larger scale.
If CCS is satisfactorily demonstrated, then I believe the plan is to use existing pipeline networks as much as possible. Otherwise, the plan is to storage captured CO2 in reservoirs under the plant where it is produced or within the vicinity.
