That's a time machine that takes a year to bring us back to an atmosphere we had 0.1 second ago (i.e., less time than it took to read this post).

@davidho Such a large facility just to negate the CO₂ footprint of 14-18 Germans.

I take it that you did not bother to read the article, but just started the snark-generator right away?
From the article:
"But the plant is not built to move tonnage. It is built to prove a process."
Seriously, being able to run a carbon capture on electricity alone is significant if it can be done at scale, and the way I understand the article, that is what they are trying to prove.
Yes, the amount of carbon captured is - again, according to the article - a mere rounding error in the grand scheme of things, but the future ramifications of a functioning electrical carbon capture are huge.
The process can be scaled up or down, depending on the amount of surplus green electricity in the grid, making it truly "green", compared to other methods that includes chemical reagents in the capture process.
@madsenandersc @davidho or they could just plant some trees instead.

@davidho Is it more suspect now, that we have viruses resembling #greenwashing, gone awry?
*sigh*
We're so screwed.

@davidho not to mention that it would probably be much more efficient to remove carbon from thick air

@madsenandersc @davidho But that would require surplus green energy in the grid to begin with
Like I'm not knocking the idea straight off the bat, but I do think this would need to NOT be a standalone plant, but something that could be implemented as a standard feature in every single factory, to function on the factory's manufacturing heat or exhaust pressure as opposed to electricity on the grid

@davidho I wonder how much CO2 Sodastream sell around the world, in a single day? I'm guessing they buy their gas from companies like Afrox which sell liquid nitrogen and other atmospheric gases, for whom a bit of CO2 is an industrial byproduct

@nick_appleyard @davidho that's a lot, thank you for the calculation. This would create an equilibrium only. Need more te revert... I think this is not feasible.
-
@davidho the article does mention that this is only a proof of concept. Are you skeptical that it proves anything of value?
@chris_e_simpson @davidho that is such a miserable fraction though that it does not prove the concept at all.
-
@madsenandersc @davidho or they could just plant some trees instead.
No, planting trees would not be useful for two reasons.
1) Trees are a relatively short term storage solution. Yes, we do have trees here in Denmark that are several hundred years old, but many types of pine dies after 100 years or so. Once they die, they rot and release the stored CO2 again. Unless they have been caught in a forest fire. Or was in the way of a property development plan. Or...
2) The article mentions that they are looking to provide the CO2 for e-fuel production. We can't realistically replace all fossil fuel processes with electric ones in a useful time frame, and in those cases you can either go with pure hydrogen (which is a bloody bastard to work with in so many ways), or you can add some carbon molecules and have hydrocarbons, which probably is compatible with everything running on natural gas today.

True, surplus green electricity is not a given, but at least the electricity (surplus or not) CAN be CO2 neutral - that is not necessarily the case with other CCS-technologies.
That said, this technology is still a decade or more away from really large scale deployment, so a lot can - and will - happen to the electricity production in the meantime.
I'm not sure that I completely follow your last part - do you suggest that the electricity for the carbon capture system should come from waste heat from the industrial production in front of it, and the carbon capture should happen on site?
My understanding of the article is that this process is for atmospheric air, not exhaust from an industrial production, but I may have gotten that wrong.
Also, I really don't think that producing electricity on site is financially viable. There is a reason why the majority of wind power in Denmark is offshore- those turbines are gigantic, but they are efficient like nothing else. Bigger really do mean better in this case, at least up to a point.

@madsenandersc @s_d_brath @davidho A short term storage system that self-propagates and that can serve as a low/no maintenance bulwark to buy us time we desperately need while we work on longer term solutions.

@davidho It's crazy, isn't it. A single small-scale LEILAC lime kiln can avoid 30,000 tonnes a year of CO2 emissions (and 100,000 to 500,000+ for a full scale plant), but somehow that doesn't make the news...).
Oh, and it's also cost competitive with the fossil alternative too.

@WhiteCatTamer @s_d_brath @davidho
You conveniently skipped part two of my answer.
I'm not saying that planting trees is a bad idea, it's just not the solution for the problem they're trying to solve here. They want to capture CO2 in order to be able to either use it for e-fuel production or to store it in the ground permanently.
Storing CO2 in trees will accomplish neither of those goals.
But, as you said, as a short term solution for simply removing CO2 from the air, planting trees is a no-brainer that might buy us another couple of decades to find more permanent solutions.

@madsenandersc @s_d_brath @davidho So your point is not that tree planting isn’t useful, which is what you said, but that it isn’t part of the plan for this organization, which sells itself by highlighting the carbon it has captured instead of the fuel it has produced, the amount of which is far, far smaller than what a small forest can capture at a fraction of the startup cost.

@WhiteCatTamer @madsenandersc @davidho additionally they will probably sell the CO2 quotas for what has been captured to someone like Microsoft so they can freely polute more. At least that is the way these companies does it in Denmark.

@davidho 150 tonnes ..... I thought that was a typo at first.
That's like me claiming I won 10€ in the lottery as a "proof-of-concept" for winning 10.000.000€

It's not there to prove a process. It's there to distract from the fact that coal-fired power generation -- essentially the same process in reverse -- still emits BILLIONS OF TONNES of CO2 each year.
Unless you see a path to negative energy prices, there's no realistic way to burn a traded commodity (electricity) to generate a common good (DACCS) while private companies are doing the opposite at a massive scale. You must brake and come to a stop before you can reverse.

@WhiteCatTamer @s_d_brath @davidho
Jay, would you stop quotefucking me? It's really annoying, and anybody can read exactly what I said a few posts higher, so you'll get absolutely nothing out of it.
But, okay, let's put it all in one post for you. Here is what Brath said:
"or they could just plant some trees instead."
- notice the "instead" at the end of the paragraph, indicating that planting trees would be more useful than creating a new carbon capture process (at least that is how I read it).
I then answered:
"No, planting trees would not be useful for two reasons."
- and followed it by two reasons why planting trees instead of testing a new carbon capture process would not accomplish what the researchers were trying to do.
I know that you read the first part of my answer because you answered it, but probably skipped the last part of my answer.
At no point did I say that planting trees was not useful or a bad idea, actually I explicitly said the opposite - you just ignored it.
And, just to finish it off, you demonstrate that you have either not read the article, or at least that you didn't understand it. They don't produce fuel, they capture carbon in order to be able to sell it to someone who produce carbon neutral hydrocarbons that can be used as a replacement for fossil fuel. And it's a TEST.

@davidho How much carbon does a healthy mature tree take out of the atmosphere each year? How many trees would be needed to sequester the same amount of CO2?
