Pretty sure they will find a way to look good on paper while still doing more harm than good
“In order to adequately test our new carbon capture system, obviously, we had to dump a couple trillion more tons of carbon into the atmosphere. Which, yeah, granted, does make it all that much more upsetting that the system didn’t actually work.”
They’ll all buy credits, problem solved!
Can we rebrand normal taxation as Non Fungible Energy Credits??
Considering that the USD is sometimes called the “petrodollar”, we’re just a name-change away.
“We changed the legal definition of carbon and have saved the planet”
They already do! It’s called carbon credits
They will probably overdo it, probably with iron fertilisation of the ocean, and start a fucking ice age.
It is a distinct possibility.
I bet they’re too dumb and poor to even know how to remove carbon from the atmosphere. Only people with really big penises and lots of money know how to remove carbon from the atmosphere. Oh, well…
They can’t even remove micro plastics from the environment and even my peasant testicles can do that
Step 1 - Take carbon from atmosphere
Step 2 - Compress carbon into diamonds
Step 3 - ???
Step 4 - Profit!
Swap steps 1 and 3.
There is a company trying to do this.
It’s very stupid.
Carbon capture in general is stupid.
First law of thermodynamics: energy cannot be created or destroyed.
In a perfect world with 100% efficient capture, it would take just as much energy to remove the carbon as it took to put it there in the first place, so if we just wanted to offset what we put into the atmosphere this year, we’d have to double the total global energy production. If we wanted to start putting a dent into “legacy carbon” we’d have to start generating more than twice the energy we use. Half that new energy infrastructure would have to go towards extracting carbon, so even though we’ve double the supply of electricity, electric costs would likely skyrocket, as electric companies now have to pay to maintain an entirely separate grid that only carbon capture facilities are using.
So unless every government in the world wants to cripple their economies for decades by forking over trillions of dollars to double the scale of their energy production, it’s never going to happen.
You do realize we have an unlimited energy source burning down on us during the day? Energy isn’t the issue here. We already overproduce during the day (though electric cars might take the load off of that in the near future).
Also you don’t have to make the carbon go poof, you just have to capture it and store in in another form (that’s not in the atmosphere). So yes, if you have a way to capture it and you use solar power (or any other renewable) you can reduce the carbon in the air.
Earth isn’t a closed system.
And earth’s atmosphere is even less of a closed system
The only carbon sequestration that makes any sense is small-scale, on-site or local (so you can avoid transport) biochar production via retort.
–> Biochar if you’re not familiar is similar to charcoal, it’s a form of “carbon black” that is elemental (isn’t going to decompose or oxidize and contribute to climate change) and when added to soil helps plants (by acting as a sponge for water, nutrients, bacteria) while sequestering carbon for millennia in the soil.
For example, a landscaping company that burns it’s waste to fuel a biochar retort and then using the resulting biochar to amend the soil used in the landscaping operations. (Think in cycles)
–> A biochar retort is form of furnace or fire pit that uses the flammable gasses produced by pyrolizing organic materials to fuel itself.
–> Pyrolysis is decomposition of organic material with high heat and no oxygen. It produces gases like methane which are burned in the retort producing particulates, CO2 and water (and that carbon does go back into the cycle) and leaves behind large amounts of elemental carbon black that is not going to contribute to climate change.
Sequestration by millions of backyard gardeners and little landscaping companies doing a little is better than trying to do it on a large scale because the large scale requires (as you note) resources. Hundreds of engineers and architects and workers driving to work for years so they can design and build a large device made of metal (that had to be mined, smelted, and shipped) and likely has an accompanying parking lot and office building would take years to break even sequestering as much carbon as it took to design and build it.
Sequestration as I describe here doesn’t require much. For example, I make biochar using coffee cans in my fire pit .
Q: But won’t burning some of the waste in the retort to heat the biochar contribute to climate change?
A: Any carbon in landscaping wastes, unless sequestered, is going to decompose into carbon dioxide (e.g. composting). Burning doesn’t add any extra carbon, it’s just that burning is a faster reaction than composting (but both burning and composting are part of the short term carbon cycle, biochar is not) . But because this burning is done to fuel pyrolysis it’s part of an efficient process.
The real danger from burning the waste is particulate pollution, but that could be controlled with common scrubbers tech.
How do you make the biochar with the coffee tins? Do you just sit them in the fire pit?
I did what this guy did, works really well.
Imagine that you have a fire in a fireplace. You’ve expended j₁ joules of energy moving that firewood into your house, setting it up correctly, and igniting it.
Now, you’ve got another fire, using the exact same amount of wood, in the forest under a tree. The wood happens to have been piled up perfectly to ignite, and–oh, look at that, a squirrel brought an ember over, igniting that fire. You’ve expended j₂ joules of energy starting the outside fire, and j₂ = 0.
Ok, let both of the fires burn out. Now let’s clean up the ashes, and we’ll call the amount of energy required to do that c₁ and c₂. Assuming that you’re moving the ashes the same distance to dispose of them, c₁ and c₂ are equal; in any case, any difference is completely unrelated to j₁ and j₂.
Carbon capture isn’t trying to rebind the molecules or anything. It’s just trying to vacuum up the carbon and sequester it. In fact, plants already do carbon capture really, really well, and they certainly don’t require a ton of energy to do it. Amine scrubbing (an ~100 year old technology) is used to capture carbon from power plant exhaust, and it’s using 0.11 mWh to scrub about one metric ton of carbon; but to create that much carbon the plant produced about ten times as much electricity.
Now, does any of this mean that carbon capture should be the first step? No! The cost is currently huge; something like $50 per ton removed, and that’s even before you consider how you’re going to get all the air through the amine scrubber. It’s definitely more cost-effective to switch to renewables, reduce usage, etc. But the time will probably come (and honestly might already be here) where that’s just not enough. When that happens, we don’t need to worry about doubling our total output; increasing it by 10% or so should do it, and if we’re really good at usage reduction, we can probably divert some of that saved energy toward capture.
Reducing usage is not cost effective because we use energy for valuable things.
Maybe if energy’s actually being wasted, that helps. Reducing energy waste is a good thing. But I mean like reducing drag on vehicles, not just shutting down what people are doing with energy, categorizing their activities as “waste”.
we use energy for valuable things.
That’s eminently debatable, and I even think an argument could be made that if it were exclusively true we probably wouldn’t be in this situation.
But even if I grant that premise, reducing usage (even energy usage on “valuable things”) can still be cost-effective. We can select times to perform heavy-load activities (such as AC cooling and vehicle charging) when the load on the grid is lower, we can replace lower-efficiency devices with higher-efficiency devices, we can employ vernacular architecture and better arborism to reduce HVAC usage, we can promote better transit and build 15-minute cities and continue developing electronic vehicles and e-bikes. There are any number of ways to reduce usage without causing disruption, especially as we develop better technologies that utilize energy more efficiently.
I guess you could just be saying “we can’t eliminate usage, we can only eliminate waste, because if it was able to be eliminated we didn’t need it anyway” but then we’re really just in a semantic argument; and one I’m not particularly interested in having.
That doesn’t make sense. Turning CO2 into methane would take at least as much energy as we get from burning methane to produce CO2, but we don’t have to turn it back into methane. There are probably other ways to capture it.
There are non-carbon-releasing sources of energy though.
They’d still do more harm
They still haven’t decided the pissing match over who can profit the most off pumping the atmosphere full of CO2.
They will urinate us to the stone age.
Reading the word ‘billionaires’ and then ‘removing … from our atmosphere’, my brain wasn’t computing.
‘Billionaires removing oxygen to sell back to us’ would make sense.
Removing oxygen from billionaires isn’t the worst idea either. Maybe by sending them down to the Titanic or off to Mars.
That’s a doctor who episode
Gotta sneak it in the side… let’s try “who can build the largest/most diamonds from atmospheric carbon”.
Oh. It’s a thing. I thought it was an onion type site for a few moments.
It’s a start. Honestly, industrial grade diamonds - the small ones with poor optical quality that go into abrasives, saws - would be even better. And that would side-step the elephant in the room: upsetting the DeBeers diamond cartel.
That said, we need a staggering amount of renewable energy to pull this off, but it’s doable. And as far as sequestration goes, the only tech we have that’s anywhere near as good is turning CO2 into plastic and permanently burying it in landfills. That’s how important this is.
I think biochar production is pretty effective and scalable. Check this company out: https://bioforcetech.com/
No, because someone would remove all the carbon and all the plants world die.
imagine atmospheric carbon becoming a delicacy. fuck…
But then the line might go up more slowly for a while! Everything must be sacrificed to the line!
Maybe it’ll be a new “line go up” metric and replace the existing line with a better one…?
Wishful thinking, I know.
There is only one chance to end world hunger, as soon as its solved nobody else can do it! Imagine the prestige!
Sadly, even that wouldn’t work, they would just start sabotaging each other and no one would accomplish it, and once again the suffering would fall on the impoverished
We already could end world hunger if we stopped feeding so much of our crops to other animals https://awellfedworld.org/issues/hunger/feed-vs-food
No, it wouldn’t.
They’d come up with dodgy and dangerous schemes that would probably just cause more damage. And that would just be before they found a way to monetize it all…
Does the liberals on here not have the foggiest clue how capitalism works?
Absolutely! Look at what happened to Mr I Want To Go See The Titanic Personally. That was with his own life on the line! Not to mention his teenage son! Please god don’t trust the rest of our fucking lives to these maniacs.
Exactly.
They’d do what they do with green washing currently; measure what they took out, but not how much the put in doing it!
Yep: Easiest place to capture carbon is probably inside a coal power plant chimney, so the winner would be the one who invested in the most coal power plants and put a little sponge or something on the end of the chimney to capture ~0.1% of the carbon emissions…
Neal Stephenson wrote a great novel about this. Check out Termination Shock.
I’d rather see a posting match over who can pay the most taxes.
Elon, probably: “You’re all trying to undo your carbon emissions while I’m making electric cars to lower my carbon footprint. If it’s not clear who’s the winner, it’s because you’re too focused on being a pedo.”
They’d find a way to fuck it up
