The tricky plan to pull CO2 out of the air

Artificial CO2 removal isn't a technology that is currently viable in any way unfortunately. Don't let big-oil convince you otherwise.

@@SomeKidFromBritain lol, i dont understand, its just a engineering problem, either it works or not. its not an opinion. Are you against cleaning the air? its not the point. the point is viability as a solution for the problem. which in the current state, it is not. is it hard to compreend?

[@pioneer_1148]

No but that isn't the point. No it won't allow us to keep burning fossil fuels and no it's not practical to just offset everything. However, current predictions say global warming is already at 1.2 degrees Celsius and it's predicted that it will reach 3.2 degrees Celsius at the current rate of decarbonisation we need much stronger measures to accelerate that decarbonsiation, most effective would be a carbon tax. But in the long run there are both industries such as long distance air travel which are near-impossible to decarbonise (short distance can and likely will be electrified but the energy density of batteries is far too low for anything beyond a few of hundred miles), where the best solution will likely be to require airlines to pull as much or more carbon from the atmosphere as they emit. Additionally in the long run we will want to pull the carbon which has been and will be emitted out of the atmosphere and to do that at scale we need the technology to be mature, which means we need to start development now.

[@peter_parkour]

​​@@SomeKidFromBritain I think anyone reasonable would. The problem is it's a hypothetical solution to a very real and imminent problem that already has real solutions. The only thing preventing those solutions right now is that it would affect profit of companies that majorly contribute to the problem, and require everyone to put their guns down in a very volatile global political climate.

To all of you, in a scenario where carbon capture can be demonstrated to function effectievly, It must be used. We could go net zero tomorrow and we still need to pull co2 out of the air. Godspeed.

[@nickmangia-forestry]

Big part of sequestering forest carbon is that you have to do something with the trees. A tree falls in the woods, it rots and releases Co2 back into the environment. You harvest timber in a sustainable and silviculturally sound way, then you get products that store Co2 in them. Ideally for this you want structural and architectural products that are durable and last hundreds of years. Not toilet paper and fast fashion construction.

[@puckelberry]

Exactly, plus the trees we plant are very fast growing and typically monoculture and nonnative further disrupting ecosystems.

[@Ninjaeule97]

Well, when you plant a forest in an area that didn't have one before even if one tree dies and releases it's carbon back into the atmosphere another one will take it's place and capture it again. The problem is we are currently cutting down more forests than we plant.

[@girak2]

Not all of that tree's CO2 has to be released. Soil has a huge capacity to store carbon, hence the no-till movement as an effort to reduce climate change.

And the older trees also emit more CO2 once dead. I’d love to hear more about how forest protection is equally important as reforestation & what’s happening around the world regarding that. And the other point is the continents most responsible for CO2 emissions. Is it really the countries or is it specific companies? How is CO2 emitted, what’s the root cause? Who are the biggest players? I’m sure some other channels (like The Story of Stuff) have already touched on these, but maybe we need to get the emitters to be more accountable by mentioning them.

Course tenets have to pay a heft premium for these builds, but it would mean a lot more if companies are willing to pay out a 400% premium for structures to occupy on the front end than to promise futures of CDR without ever actually making that investment.

[@TTB630]

To me, a BIG, BIG part of scaling down CO2 emissions is by demanding less from our lives. Traveling less, wanting less stuff in our house. Size down. I'm passionate about vehicles, but let's be honest, driving a 1300 kg car for 4 people when you are more than 90% driving alone and almost never driving with 3 or more people?... There should be like 2 seater motorcycles/cars that run 50 km on 1 L of fuel. You can design that with NO problem. Look at the XL1, It drives 100 km/L, the Velomobiel Streamliner run 84 km/L... Prohibit the making of cars that are heavier than 1000 kg, and have them run at least 30 km/L. Make these rules stronger and stronger as the years go by...

CO2 capture/removal only makes sense for things like concrete where emmisions aren't avoidable because of the chemical reaction that happens during production and once you stopped emitting CO2 in the first place. Direct air capture takes energy in the form of electricity, so even if you power it exclusive with green energy that electricity could have been used to replace fossil fuels in the electricity grid instead. Which means you didn't actually remove any CO2.

[@anustubhmishra]

that's not necessarily true though if lets say with 1 mwhr of fossil fuel energy 10 tones of co2 is produced while using carbon capture 1mwhr of energy 100 tones of co2 can be removed from the atmosphere it would be better to remove co2 then to not. but at least right now its way better to not produce co2 in the first place and use renewable energy to replace fossil fuels

Third - This is a "solution" fuel companies came up with and are actively promoting to protect their busines. And to add a cherry on top - CO2 is not the only gass that's produced by burning fossil fuels, in fact lierally all the other ones are those we shoud be worried about.

The economic argument for sequestration misses the point entirely, because they don't run on dollar bills, they run off electricity, and that energy even when it comes from renewables takes away from other uses of that energy.

[@puckelberry]

The problem with carbon capture is that its energy intensive and long term storage could become disastrous even if the tech was viable. You need to prevent any leak or chemical interaction which release CO2. The reason why trees aren't a great solution is that they get broken down by fungi etc which releases all the trapped CO2. The reason we have oil and coal to begin with is all the trees that became the fuel were during a period where microbes couldn't break down lignin allowing the trees to be buried and fossilised.

Planting trees is at-best CO2 neutral in the long term, realistically: It's only adding more CO2 to the atmosphere. Before you even plant a tree at its location, you already expel several kilograms of CO2. Then tree grows - captures a few tons of CO2. But after death it doesn't get sequenced into carbon, rather it is used for products that end up roting in waste yards, if it isn't burned directly for heating. And everything between tree being cut down and turning back into gases and ash involves tons of CO2 - the more there is between final remains of the wood being turned into underground carbon, the more CO2 gets emitted. And even in a fully natural environment, without any human activity (which barely exist in Europe or US), majority of the mass of the dead tree is expelled into atmosphere at one point or another, from roting to cow farting off last atoms of carbon re-used by other plants that grew from that dead tree. In nature very, very little of the dead tree actually remains underground. That's why it takes hundreds of thousands of years to accumulate even 1 centimeter of rock.

Not to gloss over the spike in Asian production of CO2 emissions, but how much of that has been in production of goods for the West? The issue that would be a great subject for another video is that Asian markets are keeping up with western demand for cheap goods by using the cheapest energy source: coal. In a way, western nations didn’t reduce the flow of emissions coming from their taps, they merely outsourced it to Asia.

[@henryfarberfilms]

The problem with CDR is that in order for it to work it can’t make any emissions in the process of removing carbon or it would pointless. And since long term cdr storage is only viable in certain geological conditions, there is a very tiny portion of the world that can actually do it. Otherwise you’d have to transport those emissions to places where they can be stored. CDR is just another way to pretend we’re actually making a dent in climate change but in actuality it may make it worse. Because just like with carbon offsets cdr gives a false sense of security that may make companies emit more they normally would. And since cdr isn’t that efficient you can see how we’re actually making the climate crisis worse by doing things like cdr and offsets. The solution to climate change is not to greenify our current rate and scale of production it is to simply reduce it. Infinite growth on a planet with finite resources is not possible.

CO2 does not warm the earth! It simply acts like a blanket over the earth trapping the heat in and it could just as well keep the heat out! The heating of the earth is caused by solar radiant energy being absorbed by the earth itself combined with all other things that can warm the air including volcanoes, bush fires, and all other direct human activity. The main accelerator of the warming is the higher air temperatures drying out the soils and increasing desertification. Just as the earths flora absorbs the suns energy they avoid excessive temperature rise by expiration. Exposed soils including soils under grasses release water vapour when heated until there is no moisture remaining. Sure CO2 is a problem BUT it may just be the catalyst for the starting of the change and once started the process is just going to snowball. Tackling CO2 emissions alone is not tackling climate change because simply consider the amount of Methane being released from the thawing permafrost and methane is far worse in effect than CO2. Obviously we need to tackle both BUT to do so we need abundant energy. Whilst many point straight to solar panels, the truth is that solar panels may generate about 100 watts per square metre they reflect or otherwise absorb 900 watts of other solar energy including infrared radiation, (HEAT). The heat is dissipated by atmospheric cooling, air! So for every 100 watts of generated solar power there is 900 watts plus the heating effect that the energy's usage supplies. Now if the same area was flora or adequately watered land there would be water evaporation which would cool the ground and the water vapor would rise into the upper atmosphere where the CO2 blanket was thinner and a portion of the energy would be lost to space! Solar panels are only good for a power source which does not produce CO2 once installed but up until then they are a reason for massive CO2 emissions. I know that there are two camps about what to do about CO2 emissions, well 3 if you include the climate deniers, but solar panels and even wind generators use the atmosphere as their heatsink at a time when we are seeking less atmospheric warming. Whilst everyone who advocates the use of renewables ignores the heating effect of their choices they also abhor the only real soultion to the entire crisis. Nuclear in the form of SMRs can supply electricity without increasing atmospheric CO2 but they do have a heating effect. Thankfully that heating effect can result in steam or water vapour release which can radiate most of its heat into space. Additionally the same nuclear power can produce the power for desalination and even the carbon capture industries when they are developed. Now, if the captured CO2 and the desalinated water were combined with electricity from the nuclear power stations then synthetic oil could obtained. This has the ability to finally CLOSE the carbon cycle and the need to burn fresh fossil fuels would be done away with. One further benefit is that we would not have the toxic legacy that solar panels and wind generators present.

The bathtub metaphor is a wild, dangerous oversimplification of how CO2 in the atmosphere affects extreme weather caused by climate change. CO2 in the atmosphere causes more heat which is more like more momentum. More heat, more evaporation (drier, wildfire prone land), more water moving (heavier rains elsewhere including floods), stronger winds because of more moisture moving leading (more frequent and more intense tornadoes and hurricanes). Weather has inertia, and just removing CO2 will not immediately stop extreme weather events already in motion, though it will help prevent them from getting more extreme. So we still need net zero and CDR, but its not magic that will save us and is a dangerous distraction from substantive net zero changes. Also, pollution and non CO2 GHGs are still a thing....

They say that CDR is useless unless we stop emitting CO2 in the first place, but then go on to say that stopping emissions completely could be really difficult and expensive, and therefore we could use CDR as part of our net zero strategy. But how are we going to use it as part of a net-zero strategy if we have to stop emissions first? Wouldn't that be a negative emissions strategy? For anyone who doesn't know, any CDR that does not involve photosynthesis is currently extremely energy-intensive, meaning that if you use clean energy to power CDR you could have just used that energy to prevent CO2 from being emitted from a different source in the first place, thus CDR will only reduce total CO2 in the atmosphere after we stop emitting it from every other source first.

All carbon capture methods require inputs, Energy, chemicals, land, etc. Where do we get billions of tons of resources from? every method right now would shift the problem from one industry to the next. the carbon capture plant would need resources at an unheard of rate which would shift the problem to mining companies to dig more, which would require equipment manufactures to build more equipment, which would require more resources. which would require mining companies to dig more... and all along the way Co2 is released in enormous amounts.

As long as we continue with the profits-over-people model of business I see little hope of reaching a carbon neutral outcome. So I've become open-minded (and probably too hopeful) that we can devise a way to remove carbon dioxide from the atmosphere. Of course, trying to reach a carbon neutral status AND removing carbon dioxide from the air would be ideal, humanity isn't always known for its wisdom.
