Carbon capture is 100% useless until the day that we completely stop using carbon energy sources.
Even if you use solar panels, that energy would better be used directly.
It’s not useless. Carbon capture will have to become mandatory at industries that will still require fossile fuels for a little longer after electrifying everything. Think cement and steel production. This is called on-site carbon capture and prevents releasing more carbon to the atmosphere. This is already happening.
Now that stupid thing that sucks C02 gas out of the air, yes, it’s total bollocka and will never ever work efficiently. Maybe if we eventually develop cheap fusion power.
We will almost certainly need to remove carbon already in the atmosphere. Yes, we can wish getting serious about climate change one or two decades ago would have made that unnecessary, but we’re stuck with this choice now. Short of replacing every single carbon producing device tomorrow, that’s where we’re at.
Yes we are and because of those choices back then, we are fucked. The next generations will be fucked worse with each generation. It will take centuries to clean this shit up if we actively work on it and spend over 50% of our energy budget on cleaning. If we do nothing it might never recover and be the end of us…

No, my statement is perfect correct.
Starting carbon capture while there is still fossil fuel power generation is stupid at best. If you do it for research, sure, go nuts. Anything beyond is just making shit worse.
If you have the energy and no where to get it to, that might be the one exception, perhaps but that’s it.
If you do carbon capture with energy from CO2 power then you’re literally making it worse trying to make it better. If you use non CO2 power you’re still doing it wrong because of losses, that power would be better used to avoid others using CO2, you’d be more energy efficient that way.
My point is that there are multiple companies currently doing carbon capture and its just stupid, its another one of those “look at me being smart! Pay me money!” schemes that want government money that would be better spent on replacing CO2 power sources instead.

I’m not saying that at all, I’m saying that it’s literally throwing a bucket of water on the floor and then mopping it up. Better not throw the bucket on the floor to begin with

No.
People have been throwing water on the floor for 200 years now, since the start of the industrial revolution, and right now a huge hose is connected to an enormous water tap and that hose dumps all the water straight on the floor.
You want to take a mop on that, I say that the mop is make ng it worse, because I need you to help me get rid of that hose.
Once the hose is gone, please by all means, mop away, we will need it, I fully agree. But while that hose is dumping water, I need you ) that is, the entire world) to first focus on stopping the water flow.
Edit: and just so you understand the severity of the situation: even if we spend 5-70% of the worlds energy budget on mopping 24/7, we’ll likely be mopping for the next CENTURIES to get rid of all the extra CO2 we dumped for the past 200 years.
Carbon Capture and Storage has proven highly effective at injecting taxpayer dollars straight into politicians’ pockets
That’s a half truth.
A lot of money was funneled directly into corporate profits and the pockets of carbon sequestration speculators.
If you Google anything the first results are sponsored links.
…and that should tell you all you need to know.
As much as I agree with the implication that O&G companies latch on to every potential carbon sink as a way to greenwash themselves, carbon capture does have merits.
However, the only ones who can currently utilize carbon capture on a significant scale are the ones who produce a lot of carbon to begin with. Technology will have to advance drastically for it to be a carbon sink effective enough to offset emission to the point where emission cuts can be scaled down.
Source: Last year I was involved in surveyon an area that was planned for huge-scale carbon storage after capture.
it’s much more nuanced than that though.
Hey, look at us, we are planting 2 bn trees that are ALL THE SAME.
None of the methods they present as solutions are even close to being viable. The ones that do look promising, however, are where they bind the CO2 to tailings.
Okay? And how are we supposed to deal with the emissions currently in the atmosphere? Even if we abandon all technologies that generate greenhouse gases overnight, we still have shit in the atmosphere warming the planet.
The most compelling strategy I’ve heard is biochar. You immolate organic matter in a medium like nitrogen so you don’t get carbon dioxide, and then you bury the char or use it as fertilizer. The char is relatively stable so shouldn’t create much in the way of carbon dioxide once it’s formed, and because you make it in an oxygen-less atmosphere you don’t get more greenhouse gases from making it.
Absolutely, I also think Biochar is very promising as one way to recapture atmospheric CO2 and to compensate further emissions.
While I understood the production process to be a little different, the benefits of Biochar can’t be ignored.
- low in energy consumption
- low in recourse cost
- very good scalable
- no hidden science or process
- the stored carbon can be used as a soil amendment
The process may be a bit more complex than I understood, but my understanding is that the gist of it is to “burn” plant stuff in a way that doesn’t create carbon dioxide or other greenhouse gases. One way of doing that is to use a chamber flooded with nitrogen or similar inert gas. No oxygen means carbon can’t bind to two oxygen atoms to create carbon dioxide.
I’m confused, how can you ‘burn’ anything without oxygen? Burn literally means to oxidize
That’s why it’s in quotes. You’re subjecting it to high heat, which would normally cause it to burn, but because there’s no oxygen it chars instead.
biochar is awesome
I don’t understand. Biomass already isnt CO2. Why do we take an extra step?
Because when biomass rots, it creates CO2. By charring it you’re making the carbon more stable and less likely to become CO2 in the future. It also won’t rot when charred.
So how do we produce biomass? Plant more trees? Which we already do. Then in how many year we cut it down and biochar it instead of using it reporposing it for something else? I’m kind of failing to see the benefit. Just seems like an alternative that isn’t really any better than some of the other good alternatives.
Make algae ponds, harvest the algae, dry it, char it, bury it. Algae sucks up carbon dioxide like crazy, the downside being that it releases the carbon when it starts to rot. By charring and burying it, you’re helping to make sure that carbon doesn’t re-enter the atmosphere.
Ah. I didn’t think of algae. Might be a good reason to harvest all the algae blooms from the fertilizer run off.
Yup. And they’ve been working on it for 20 years, and have yet to illustrate any scale that would effect the problem.
This binary thinking from activists really annoys me.
How is that binary?
You seriously need to ask? You do not want to actually understand how it may work, how much it may cost, how realistic it is? And instead you would use “energy companies = bad” and if they also want to participate in carbon capture, then it is ALL you need to know and reject the idea simply based on this. You do not see this as binary??
Companies = bad
Or a bit more nuanced: Under a capitalist system, the first order of business is to make money. That does not have to be bad a priori, but with the given scenario of carbon capture, the meme points out the fact, that it is mostly greenwashing. Does that mean carbon capture is bad? No. Is it the best way to tackle climate change? Absolutely not. Does it make them money and delay actual action to combat the climate crisis? Yes.
But that wouldn’t be a meme, would it?
Making a meme does not mean that you have to do it as a one-bit stupidity. That’s not a valid excuse.
There is no single technology that will tackle climate change, it will/does require combined approach and carbon capture quite possible have a role there to play too. And as for companies making money, they do make monies on solar, wind, electrical cars, and they will make money on carbon capture, hopefully. If there is no money to be made, then it would be a very good indication that the idea is dead on arrival.
System change, not climate change
yeah, no one’s getting distracted
Not quite
They said Google.
Good thing I never Googled it
Rich companies have the best SEO?
Carbon capture will only work if the capturing and storage of said carbon uses less energy than it took to release said carbon.
So far I have yet to see that.
Did you mean Regulatory Capture?
Ever heard about trees Mr Techbro
