So Occidental Petroleum, a big American oil company, they are really good at a kind of oil production that involves injecting CO2 underground to squeeze more oil out of old wells. So when they heard about this technology to pull carbon out of the sky, they thought, wait; this could work for us. They plan to put some carbon underground just to store it.
This is worse than a zero sum game. Every litre of oil produces multiple litres of CO2 gas.
Sorry, but not that uplifting at all.
Technically, it's uplifting if you are a deposit of oil.
Doesn’t that mean that the oil produced here emits less net CO2? Since CO2 was used to extract it, taking it out of the atmosphere, that mean that the entire process of extraction and consumption emits less net CO2 than more traditional methods.
Hardly carbon neutral, but an improvement.
This is greenwashing at its crudest.
Like open/closed source, if they don't provide the source and data very likely they are lying to you.
damn.. can't even trust NPR anymore.
Good news everyone! It's time to present my newest invention: a solar powered CO2 scrubber! To activate it, just throw a few of these small seeds on the ground and wait a few years.
Unless your grid is running on 100% renewables and has excess capacity carbon capture causes net positive emissions.
This is just another attempt at greenwashing. They're presenting carbon capture as a way to keep burning fossil fuels. Until our energy generation is fully decarbonised, there's no point even thinking about carbon capture.
I mean, someone needs to be thinking about it and perhaps even building infrastructure so it can be used once the grid is clean but it's not something that should be in use
No, it's not. But now that everyone is realizing carbon credits are bullshit, they need some other excuse to prevent them from doing what needs done.
I can't believe we're still burning fucking coal. It's incredible.
I've always held high hopes (albeit uninformed hopes) for carbon capture... Thanks for the links, looking forward to reading them.
Fuck the naysayers: Any realistic long-term solution to this needs to include removing CO₂ that's already in the atmosphere. The best time to start developing this tech would have been 50 years ago. If we don't do this now, someone else will be saying the same thing 50 years from now.
Climate change doesn't have a single-target solution. This tech may not be very impressive yet but it's important we figure it out eventually.
I agree but this is not the way to do it.
Oil companies pumping it underground is just a way for them to justify business as usual.
Removing co2 from the atmosphere requires energy input, If that energy comes from a co2 producing source it will never work.
Developing nuke/wind/solar co2 extraction is possible but this is astroturfing of the highest order.
I think it's more nuanced than that.
Some people are saying it's bad because they're using it to "produce more oil" - and that I don't buy. Sure, they're directly pumping oil with the CO₂ they inject - but this is oil they'd extract either way, with or without direct air capture. In a strict comparison between the two situations, doing it with direct air capture is less bad than doing it without.
The actual harm that could come from it is mentioned in the article - that they want to use this to justify pumping for longer than they would otherwise. It was actually a bit shocking to see how brazen and open the oil company representative was about that. If they succeed in using this to justify continued pumping, then that's definitely bad. I don't think the politics will work out in their favor though, especially not 10 or 20 years from now.
But in the long-term I still see this as an absolute win. Above all else, what this technology needs to do is exist and be effective. For that it needs to be invested in heavily, and built and tested and run even when it's ineffective and unprofitable. We aren't anywhere near the stage where we have the technological capability to actually do direct air capture on a scale that matters globally. Helping us get to that point, to me, makes this move still a net positive. A pragmatic good.
Yeah, it needs to be developed and we need to invest in running it off renewables, but our immediate priority needs to be stopping emissions
While I don't disagree, I think it's important to note that "our immediate priority needs to be stopping emissions" doesn't mean "we shouldn't be investing in this yet". Technologies take time to develop and reach maturity - sometimes decades. If we wait on developing the tech until removing CO₂ that's already out there out-prioritizes reducing ongoing emissions, then we'll be multiple decades behind where we should be when it matters most.
I think this is necessary, but we need to stop trying to make it profitable or using it as an excuse to pollute more. This needs to be paid for through taxes. Any other source of money that is enough to actually get the job done will result in the carbon going right back into the air. Using it for extra oil extraction is doubly bullshit.
I both agree and disagree with this. If it can be made profitable, then all the better - because then economics and policy can combine to bring it about faster than either would alone. But if it can't be made profitable then I agree absolutely that it should be done anyways with tax revenue.
Long-term it's definitely not good to use it as an excuse to pollute more - these won't do an ounce of good if they only exist to offset emissions we still produce. In the short term though, allowing carbon capture to act as an offset for emissions could still be a net long-term positive, in that it would shift the economics more in its favor - allowing faster development and a wider buildout. This assumes that the industries that use it in this fashion do eventually decarbonize anyways - which you could perhaps guarantee by having carbon capture stop counting as offsets at some designated future date.
I think the pragmatic solution is to introduce yearly shrinking carbon caps, and allow them to be offset with carbon capture for a limited time - say, 10 or 15 years after the "net zero carbon" goal date. After that it's all about building up that net negative number.
If you’re going to capture any of it, you should build your capture factory right next to the source such as a blast furnace. In normal air the concentration is so low that you end up playing that game in hard mode.
How about make the polluting company purchase this and plop it on top of their emissions tube?
The rules will only say “no carbon emission”, and however a company wants to make that happen is up to them.
This is the way I would want to see it happen. If pollution tax is high enough, it will incentivize companies to act more reasonably. Hopefully coal power plants will shut down permanently while blast furnaces will be modified to meet the new requirements. Processing all of that CO2 won’t be cheap, but steel production has to continue so the company doesn’t really have that many options. The government could also support the transition so that production won’t disappear into other countries.
i thought i read somewhere its still more efficient to just plant trees or some biomass.
I think algae is more efficient than trees. Not sure tho.
Thing is, the tree is mostly carbon at the end of it's lifespan. So then what? You merely delayed the problem at that point.
Even if you don't decompose the material or burn it, you will have the carbon released back eventually.
