CO2 pipelines exist. This map (via RexTag Strategies) shows one of several CO2 pipelines leading to the oil fields of the Permian Basin in West Texas. Natural CO2 deposits are actually being tapped and mined in Colorado.
The CO2 is shipped to Texas to assist in petroleum extraction. Wouldn’t it be better to use some of the extra CO2 from coal fired plants for this purpose? I mean, rather than digging up extra CO2?
(Isn’t that crazy? I wonder how that got going! Where were the NIMBY crowd then?)
Note that the pipelines pass through populated areas in New Mexico. A more complete map of comparable pipleline systems is posted, but based on what I see in the hallways of my workplace, I believe even that one is incomplete.
However you feel about any of this, it’s interesting to note that the extant CO2 pipelines in the US have been federally subsidized in the pursuit of domestic fossil fuel supplies (see p 15).
Conceivably under extremely unfavorable circumstances that CO2 could escape and kill somebody already. Dangerous industrial processes happen all the time. Trains and trucks and pipes full of who knows what go every which way.
We can neither afford to allow them to go unquestioned nor to stop every one. What we need is a consistent way of thinking about them, not advocates and opponents slugging things out over and over using whatever weapons are handy. What happens now is not just capricious and random. It damages our capacity for collective thought every time.
