[quote=Anonymous]2000 miles of pipeline proposed for 5 upper midwestern/plains states. Plan is to transport CO2 from ethanol plants to ND oil fields. The CO2 will go into the ground. It will also, according to the Sierra Club, allow for additional extraction from wells that have been depleted by current fracking methods.

My first thought was CO2 leaks, since CO2 is heavier than air and causes asphyxiation--I know people have died in pits and such because of CO2 accumulating at the bottom, and it can happen pretty quickly. There have been rare occasions in which some kind of natural phenomenon causes CO2 to pool in an area killing people (almost 2000 people in Africa were killed in the 80s by a CO2 eruption). Sierra Club also mentions that.

Sierra Club point that out, also emphasizing that this is not a "real" climate change solution ("greenwashing"). No idea what the net effect would be, which seems to me to be the most important aspect.

Pro? Con?

I do think they need to speed up the development of methods that sequester carbon dioxide in cement. [/quote]
