Worth the click! I had no idea there were such things as limnic eruptions.

#22Ummm. Dumb question here. Why do we have CO2 pipelines? Wouldn’t it be cheaper to capture CO2 from the atmosphere at the location where the CO2 was needed?
Good point. The answer is: Ridiculously high Government subsidies. In other words, this is simply a stealth tax on the public where the only winners are corporations which benefit via very generous tax credits.
It's ANOTHER subsidy for the fossil industry. We (earth) already pay [1] them around us$1T/yr to accelerate our demise. CO2 offset subsidies are on top of this [2].
So instead of stopping X, we pay them to continue X and then pay them to cook some books about X. Insane. We will be the first species driven to extinction because the alternative wasn't profitable.

Seems to be a shady political operation to help the fracking industry in the US:
> Huffman notes that today most of the carbon dioxide transported in pipelines is used for something called "enhanced oil recovery." That's a process where oil companies inject CO2 into oil wells to boost the pressure and pump out more petroleum.
> Currently over 70% of carbon capture projects involve "enhanced oil recovery," says Bruce Robertson, energy finance analyst at the Institute for Energy Economics and Financial Analysis, a nonprofit think tank. The CO2 in the pipeline that ruptured in Satartia was headed to an oil field where it would have been used to extract more oil.

Legitimate question, but the answer is simple: No.
The cost of CO2 capture largely depends on the concentration of CO2. Transport is relatively cheap. If you capture from the atmosphere, that's the most expensive thing you could possibly do. That's also why people try all kinds of things to increase CO2 concentration. Like Oxyfuel technology, which basically means you're burning without nitrogen, so what you end up with has a higher CO2 content.
It's also why CCS is hard in industries where by design CO2 concentration in the exhaust is low (Aluminium is one of them), and why most of the existing CCS projects are at facilities that by design have high CO2 concentrations (mainly gas upgraders).

If we're gonna compare... CO2 dissipates but nuclear accidents cost $100B+ to cleanup and decades - to Sally Average voters, Fukushima was the third strike (after 3 mile island and fukushima): if the Japanese can't safely operate nuclear, then no way is Sally gonna trust Homer Simpson. And even if she can believe, good luck explaining to her friends and family, let alone potential renters and buyers of her largest fi…
> no way is Sally gonna trust Homer Simpson.
The Simpsons and its consequences have been a disaster for nuclear power, and the human race.

It's cheaper to capture it where it is concentrated, at the source (eg. power plants).
Is the efficiency gained by capturing it from a stronger concentration enough to offset the costs of building pipelines?
Why not burn wood in a room near the destination site and get extremely concentrated CO2 right there and capture that instead?
Are pipelines somehow even more economical than that?

There's nothing shady about this practice. It's simple science.

#29Can we please avoid mass hysteria about pipelines? As you've seen, bulk shipping by rail is incredible stupid.
Can we please avoid mass hysteria about rail? As you've seen, bulk shipping by pipelines is incredible stupid. Moving dangerous stuff is always risky, there’s plenty of disasters from both. https://en.wikipedia.org/wiki/List_of_pipeline_accidents From 1994 through 2013, the U.S. had 745 serious incidents with gas distribution, causing 278 fatalities and 1059 injuries, with $110,658,083 in property damage. US: From 19…
The science is conclusive that pipelines are the LEAST dangerous and leaky method of transporting anything.

Neither of these things are bad.
