The train idea hurts my mind as it's generally a transportation system that runs on fossil fuel, and the energy is not "free", as the added weight ends up taking more energy for the train to accelerate, and then you have to factor in the percentage of runtime that actually involve braking, which shouldn't be often as this is a train. Not to mention that the size of each unit is so small, it's hard to imagine it making an impact. Every little bit helps I guess.
Also, the energy gained by breaking could instead be used to power the electric train engine, making the train use less energy from the grid, making it easier tostop using gas to generate enough power. Regenerative breaking is a good idea in it self, does not need a shiny co2 capture thing.
I hope I can explain with an example. You move an empty train to a mine up on a mountain. The train needs some energy because he needs to move his empty weight up the mountain. Things that fall down have energy. The heavier it is that falls down the more energy. Now you fill the train up with heavy iron ore. You didn't need to move the iron ore up the mountain because it was produced there. The train is now much heavier, so if he moves back down the mountain, he will produce more energy than it was needed to drive up. You harvest the energy with the "extra energy" of the cargo with your brakes. This is a system that is already used in many ways, but I doubt it would be a good idea to use it as said in this video because you don't speed up to use your brakes just to "get energy".
Very dissapointed about this topic. I've never heard of this "solution" but I can find a lot of problems with it in 10 seconds. First, you will increase the train air friction (no such things as free energy, remember?). Second, if you do recover the braking energy, use it directly on the purpose of the train - transporting (hybrid locomotive for diesel or put it back into the grid for electric ones). Third, do not attempt to suck CO2 from normal air (remember what ppm actually means) and apply this (heavy) machiery near a power plant that emits CO2 like crazy, and at the same time you dont't have to move the weight of this carbon capture device, but rather move... people and goods... This is what trains are for, not for catching molecules of co2. Etc, etc. At least, at the end of the video you mention REAL solutions for ccs - trees.
Lol they think they have free energy 😂, They are ignoring the solar panels are useless and all the energy comes from an old school diesel engine, Not even a deltec.
Trees die, decompose and pump back CO2 into the atmosphere. The only real (theoretical) way of reducing CO2 is using nuclear energy to transform CO2 into other stable fluid or solid forms of carbon chemicals, and store it safely somewhere where the carbon won't escape back into the atmosphere after a few hundred/thousand of years.
Either way, the most energy-intensive trains don't brake all that often. Freight trains travel point to point and don't usually stop. The ultra direct high speed service from, say, Barcelona to Madrid only accelerates once (at Barcelona) and maintains its top speed uninterrupted until Madrid, where it decelerates once on arrival. You're not saving that much energy. Trains don't have regen braking because it's this huge solution, it's just that fitting regen to an already existing electric motor is so easy and cheap that it's convenient for that little kickback you get from the power company.
To be fair, after coming here via Thunderf00t, most videos seem fine. As with all 'science influencer channels', they must never taken fully as fact. So I subbed.
@@dfsafadsDW Most channels like this have a staff, they try to make it seem like a one man show but reality is its a cast/crew. They have mangers, writers, illustrators, video editors etc.
I don't know who came up with the (stupid) idea that trains have a surplus of energy. any energy recuperated from regenerative breaking should be store back in batteries in order to move the train and reduce their energy consumption (same way it is used in electric/hybrid cars). solar panel are nice, but their *average* (daily) output is about 100 watt per square meter. even if you completely cover the train with solar panels that is about 5 horse power per train carriage, so no energy surplus there either.
Why even put the solar panels on trains. Its such a stupid idea. You're literally just lowering the amount of energy they produce to look more futuristic AND weighing down trains a touch, leading to even more energy loss. Just...??? I cant believe I used to watch this pop science guff
@@scoutbane1651 wow I didn't even take that into consideration. you are absolutely right, it will weigh down the train, and half of the solar panels will always be in the shade 🤦🏻♂️

2:45 except that the train now has to use more energy to move because of the extra drag so essentially i don't think it's that much different from using a fan for this.
It's even a more stupid idea than that! Why wouldn't you just use the energy captured by regenerative braking to help in re-accelerating the train itself and save on the fuel required, thus not produce as much CO2 in the first place? That would be MUCH more efficient than all the BS being spewed here!
The train "idea" is likely appealing to a toddler. It speaks volume about the pseudo scientific skills those guys have. They are precisely what is dangerous on internet, spreading stupidity all over.
Wouldn't the braking energy be better used to propel the train? Trying to do it on the train will only add to weight and energy needed to accelerate it. The fan is not the energy intensive part of the process so putting it on a train is less efficient.
I don't understand why you claim that this would not require energy to push the air through those train carriages, 'because they're already moving'. Wouldn't such a car increase drag, forcing the engine to work harder, thereby requiring more energy?
Many magnitudes more energy can be recovered than is indirectly lost due to drag forces placed upon the train from aerodynamics, rolling resistance, and mass acceleration. We would also be happy to show you exactly how meaningful Rail DAC can be. The global rail system has the advantage of being very well established and very, very enormous.
@co2rail That’s absolutely not true and breaks the laws of thermodynamics. What you’re describing is free energy, it will always take more energy to keep the wind turbine accelerated than it will recover.
The title is SPOT ON ! This video is why channels like this are entertainment and not a science resource. For that you have Thunderf00t, potholer54,Sabine Hossenfelder, NileRed, PBS Space Time & co, Sean Carroll, etc.
It would probably be better for the environment for the trains to use that energy to charge a battery to help power the train, rather than to use it for carbon capture, which has always been a technology that has been not been worth even the energy cost, let alone all the other costs.
Yeah that's definitely a better solution. However, it can be used in existing trains which is significantly cheaper than replacing the entire world's fleet of trains with an electric alternative. Hopefully it's used as a transition technology and an excuse for people to stop moving to electric altogether.
@wW-ns6uu I don't think it would be. Something that is always better than carbon capture is just paying to reduce your carbon emissions, dollar per CO2 reduced, has always been better and probably will always be better. CO2 capture technologies are literally sponsored by oil and coal companies to make people feel less bad about using their products.
You are aware that the very people that say carbon capture is impossible now said EVs where impossible 20 years ago right? Predicting what will be possible in the future believe it or not is still guesswork, it’s not breaking any laws of physics. And more importantly we want it to happen
@@josephsalomone there is so much independent research regarding electrochemical CO2 reduction now because it is one of the few tangible technologies that can reduce atmospheric CO2. The thing is - we will always probably need fossil fuels e.g.aviation, steel production. The technological world where we completely stop using them is so far away compared to the rate we need to reduce CO2 emissions. Even if this application is kind of stupid (and this video does a terrible job at explaining CO2 capture tech - it's poorly researched) it is something worthwhile implementing in other applications.
@wW-ns6uu We do not need fossil fuels for airplanes nor for steel production. There are eco-friendly ways to make steel, and several steel mills are already carbon-free, also known as green steel, and while no one is building them or even researching them, much like green energy is the 90s, many proof of concepts of eco-friendly planes exist. Seems like a pro-oil argument you got there. Dollar for dollar, carbon capture just does not make any sense. It is why no company that is serious about being carbon neutral is making these. Power companies know it is cheaper AND more effective to just switch to green energy as fast as possible rather than to even bother with carbon capture. The science behind carbon capture isn't great either. Yes, it is possible, but CO2 is only 300 to 500 ppm, 0.03% to 0.04%, and we want to reduce it to 100 ppm. The numbers are just too low for the tech to ever be effective, and the idea that some building size capture facility on the ground is going to remove CO2 from the upper atmosphere is ludicrous.
You are absolutely right. However right now on every diesel train in the world, this regenerative braking energy (called dynamic braking in rail) is completely wasted by passing it through large resistor grids mounted atop the locomotive during every stop or deceleration. Even on electrified lines, if the transmission losses of supplying the regenerative braking energy back to the grid exceed the drag forces of the car, it is advantageous to perform direct air capture on-board the train. This point occurs over fairly short distances given the *realitively* low transmission voltages of catenary lines (e.g. 3-15 kV). Also, many magnitudes more energy can be recovered than is indirectly lost due to drag forces placed upon the train from aerodynamics, rolling resistance, and mass acceleration. We would also be happy to show you exactly how meaningful Rail DAC can be. The global rail system has the advantage of being very well established and very, very enormous.
@@co2railOk. . . but why use the energy captured by regenerative braking for carbon capture? Wouldn't it make much more sense to just use it to help re-accelerate the train and thus cut down on CO2 emissions from burning diesel to begin with??? Answer: YES!!!!
Not true, used Google and did the math. Carbon capture is a more efficient use of renewable energy than using the same renewable energy to 'replace' fossil fuels in daily electricity generation. (Efficient in the sense, more CO2 removed per kWh)
I'm no engineer/physicist/scientist but this just seems like a stupid idea. Electric trains already have regenerative breaking which puts energy back into the system so you may as well use that energy for a carbon capture plant on the ground. Yes it could work for diesel trains but seeing as most countries that operate those don't care about climate change then good luck getting railways to purchase and use these.
Congrats on becoming a target for Thunderf00t- he tore this episode apart in his latest Busted vid. Wonder what else he’ll find in your back library of mistakes?
The fact that every advancement made to clean up this problem is used by the oil companies as an excuse to just keep drilling is a real kick in the nuts.
Think of it this way: no one would use carbon capture unless it makes them a profit. This is a great way to make carbon capture commercially viable at least initially until the technology has matured enough to be widespread
The framing of climate change as a technical "Problem" rather than the destruction of society embedded and inherent in capitalist growth and the othering of nature is part of the reason we are where we are.
The reason why carbon dioxide is stored in petroleum reservoirs and not inside rock formations in Iceland, is due to the reservoirs containing oil and gas have tight seals that make sure the CO2 does not escape (The oil and gas would have escaped millions of years ago if these seals did not exist). You cannot store it in random rocks, as the porous structure and fractures in the formations will cause the CO2 to leak back out.
I think there's something about the volcanic rock they're using that chemically binds the co2 so it's locked in and not what is essentially tons of tiny co2 balloons that can be popped to let it escape
I just don't understand how a channel claiming to be a proponent of science could post a video with such blatant pseudo science as the train air capture system. I came here from Thunderfoots latest video saddened to realize one of the channels I subscribed to and thought were some good blokes trying to edutain the internet clearly either did not care at all about due diligence or simply were motivated by ulterior means to slip in pseudo science amongst the real science on the channel.
The system is powered by regenerative braking which captures energy that is normally just wasted. It's still a bad idea overall, but there's no perpetual motion or breaking laws of thermodynamics here.
@AbruptAvalanche They claim that the train will not only not need energy, but will also clean the air. This clearly violates thermodynamic and Gibbs free energy
This idea has a "solar -roads- FREAKIN' roadways" feel to it. But more ideas are good, as some will probably work. edit - corrected to show Dave Head's input.
@@CLOCK-WORKmethane is more potent of a greenhouse gas (and you’re still kind of right as it is still a big problem too), but the quantity of CO2 way overpowers methane. There are cool developments though, like special cow feed that reduces the amount of methane cows produce (they breathe out a ton); also there are ways being developed to keep cow waste from releasing methane into the air after being processed. Cool stuff!
Agreed. It would be nice on paper, but I can’t see trains, especially since public transportation isn’t being utilized enough, ever contributing much to carbon collection. Also wouldn’t trains use more co2 from energy than the co2 that they would take out of the air?
You could say the same about not taking a flight, or using an electric car. The point isn't about how much we capture today, it's about how much we could capture at scale as the tech improves. Without it, we will miss our targets, so you better hope it works.
@@hamsterminator the issue is, it doesn’t yet exist on a workable scale, and may not exist before we reach the tipping point of climate breakdown. Governments and businesses are today using carbon capture as an excuse to cut emissions by less than they should. It should not replace the significant emissions reductions that we need to make, but at the moment it’s being used to greenwash
@@johnwhittaker311 the only way that carbon capture technology would allow companies to avoid cutting emissions would be if the current emissions targets, which are set to represent a world without carbon capture tech, weren't adjusted. People are applying the rules of today to the tech of tomorrow. Its exactly the same nonsense people parroted about electric cars being slow and having no range while basing their assertions on decades old tech.
@@hamsterminator we have the technology and resources and knowledge to fix climate change now. Just a lack of willingness to do so, which mostly stems from the fact it's not short term profitable to the companies who already have invested in the old fossil fuel system. All these future hypotheticals are just a distraction to make no meaningful changes now. This is intentional and the companies pushing this narritve know it. You mention electric cars. I suggest you think about this question. Are electric cars here to save the planet or to save the car industry? We've had a viable solution to reducing car emissions for decades in the form of human centric walkable cities with public transport. Electric cars don't actually save a whole lot of emissions. Maybe 50% over the life cycle of the car. (Ebikes are the new tech everyone should be excited about, they have MPGe in the thousands and use 1/10 the resources of an electric car). Yes in isolation EV's are a good technology and it will have specific use cases in the future BUT it distracts from the problem of car centric cities and car centric culture. If you have an electric car that saves 50% of the emissions but you sell 3x the number of vehicles you have made your problem 50% worse, this is the trajectory we are currently taking.
This video highlights one of the biggest issues with the effort to tackle man-made climate change (besides uncooperative governments): over-reliance on 'new technologies' instead of, you know, getting corporations to cut down their emissions in the first place. Too much attention is given to startups with tech buzzwords and fancy CGI promo videos of futuristic-looking pods while factories and such continue to pump out greenhouse gases unaffected. We have to be tougher on corporations (and associated billionaires).
And by extension be tougher on consumers for buying and using carbon emitting technologies, services and products - all of which come from the corporations which we skewer on a daily basis. High five!
@@4203105 if you look at way rare earth metals are mined as well as where they are found. Add that with how we will need alot of it with over 1000% increase I production for some.

Rare earth metals are usually found with thorium and sometimes arsenic which damages ground water erodes soil etc. Mining at the moment also emits 10% of all co2.

from what I understand problem with plants is that when they die they that release carbon back, so they can't account for the carbon that was once previously deep underground that is now in our atmosphere. Not that grasslands and forests aren't good they just cant put carbon back into deep Earth storage like the way millions of years of organic matter did. That why they want to sequester and store it again or ideally we just don't pump the oil from the ground at all and it stays there.
@@ayoCC plants are actually pretty shit. Photosynthesis uses less than 1% of the suns energy a plant receives. But at least plants are cheap and they don't produce CO2 while being built and run.

it seems that this magical Harry Potter Hogwarts train can ignore the second law of thermodynamics ("no extra energy needed" claim), also ignores the fact that carbon capture costs more per kilo than the same kilo of fossil fuel (the problem of economical viability), and also that in studies carbon capture facilities emit more emissions than they capture.
I grew up in communist Eastern Europe where we had to face a lot of political propaganda in which ideology was above science and laws of physics (and we all had to agree with the ideology, otherwise we would have faced harsh consequences). This video with its complete lack of understanding of basic physics brought me back to the scary old days...
IMO carbon capture tech is a complete red herring. A much more efficient system already exists on the form of Bogs and Swamps. So they just need more green stuff. 1/2
I doubt feasability is very high. Electric trains already return the energy gained from braking back into the grid. I once had a talk with someone from the swiss rail company (SBB) and he said that on average, for every three trains going down a hill, one could go up for free simply by the energy recovered from braking. On those electrified networks you don't gain a lot by using that energy to power carbon capture technologies because you now lose the energy recovery into the grid, and have to make up the difference by supplying more energy from your generators. Also if they use the energy from braking to power carbon capture cars, it looks like they only capture carbon when the train brakes, and modern commuter trains brake much faster than a freight train. In the end, I think this technology may only be viable in banana republics that run non-electrified networks *cough* the US *cough* but also can afford said train cars. And in those situations, you may need to evaluate whether this even offsets the diesel burned in the locomotive, or if it would be better to electrify the network instead.
Not great, carbon capture is not a feasible technology and will probably never be a feasible technology. All current carbon capture technologies actually produce more CO2 than they consume. Honestly, just a huge field of algae would work better. How carbon capture produces CO2: Power Costs Transmission Costs Repair Costs Transmission Repair Costs Setup Costs
@radio4active Most Europe trains are electric, most American trains are diesel, but the carbon capture wagon would probably be more expensive than switching to an electric locomotive while also consuming less carbon than the train produces. So yeah, not feasible.
@@josephsalomone And all the CO2 created building the capture plant and creating the materials used. Maybe a one time cost but if you’re making thousands of plants it adds up.
You do realize that Iceland is seismically active. So carbon being stored underground in Iceland isn't a very good idea as all it would take is the the mid-Atlantic ridge to form fissures to rereleased that captured carbon. Also, plants aren't the answer either. Plants are carbon sinks, however, it is a slow, temporary sink. Trees cannot actively remove carbon from the air, but use a passive system. Also, photosynthetic plants require sunlight to convert carbon dioxide and water into sugars and oxygen. However, when they cannot get that sunlight energy, the process works in reverse because it is easier to get energy from sugars and oxygen (which is how most animals on the planet survive).
What do you mean it doesn't work? Of course it works, there have been multiple demonstration plants like Petra Nova and Boundary Dam. Their economics are difficult in a situation without carbon pricing.
@@gregorymalchuk272 multiple demonstration plants that did not work because they leaked that CO2 right back into the atmosphere, sooner or later. I'm actually not sure why they are all so shit. Maybe it's just a matter of doing it better, but so far it doesn't work.

This video is what happens when you mix opinion with science fact. This behavior is why I abandoned this channel years ago. Injecting opinion into education is the absolute worst.
Doesn't this create additional drag on the train? It's also extra weight that needs to be set in motion and it likely takes space away from passenger capacity. Things like solar panels can be used to decrease the train's energy usage. So I'm not sure if there are significant gains to that idea compared to stationary CC units

Well, at least a lot of the comments here see the glaring issues with all this, glad to see it a lot of people did not fall in this stupid trap. Why did AsapScience fall into that trap? this video has a real "Undecided with Matt Ferrell" feel to it
We here at CO2Rail have read most of the comments and the following answers cover a good majority of the questions: 1.Right now on every diesel train in the world, this regenerative braking energy (called dynamic braking in rail) is completely wasted by passing it through large resistor grids mounted atop the locomotive during every stop or deceleration. The amount of energy that is wasted every year is enormous and equivalent to over 100 Hoover Dams. 2.Even on electrified lines, if the transmission losses of supplying the regenerative braking energy back to the grid exceed the drag forces of the car, it is advantageous to perform direct air capture on-board the train. This point occurs over fairly short distances given the *realitively* low transmission voltages of catenary lines (e.g. 3-15 kV). 3.Many magnitudes more energy can be recovered than is indirectly lost due to drag forces placed upon the train from aerodynamics, rolling resistance, and mass acceleration. 4. There is a fairly simple calculation that anyone can do that will show that what we are doing is about 500% more effective from a carbon mitigation perspective than using that same amount of stored regenerative braking energy for additional propulsion. Happy to provide the equation if you are interested. 5. Our research paper was authored by some of the best in the field from such institutions as MIT, Princeton, University of Toronto, and University of Sheffield. 6. Everyone loves trees. Yes we should plant more. However, to do what needs to be done, it would take a land area approximately the size of North America. Must be aerable land, too. Then there is the fire issue where the stored carbon is released right back into the atmosphere. Trees, unfortunately, will not get it done. 7. We are not funded by oil and using our captured CO2 for Enhanced Oil Recovery is prohibited in our Code of Ethics. We simply will not do it. 8. If we do not quickly decarbonize, no amount of direct air capture will matter and it is a complete waste of time and money. However, once we do decarbonize, DAC can bring atmospheric CO2 concentrations back down to pre-industrial levels. We would be happy to show you exactly how meaningful Rail DAC can be. The global rail system has the advantage of being very well established and utterly enormous. Love the questions. Happy to answer more. ---CO2Rail Team
"it would take a land area approximately the size of North America. Must be aerable land, too. Then there is the fire issue where the stored carbon is released right back into the atmosphere. Trees, unfortunately, will not get it done." Could you provide a source for this statement?

I am shocked that @asapscience did not upload or correction statement nor even bothered to answer the comments. Thunderfoot uploaded a video about the topic, of course. But the comments here already mentioned months ago how stupid the carbon capturing train is.
Confused european: Why the heck would you want to carry around a CCS system when you can just put the energy back into grid ... "As a result, electrified rail is currently used on less than 1 percent of U.S. railroad tracks while electricity supplies more than one-third of the energy that powers trains globally." Oh THATS why!
We're doomed if people think a carbon capture train is anything but pure stupidity. I thought this was a science-based channel. I was clearly mistaken. Is it April Fools Day?
Those trains already return the energy they get by breaking back to the grid (inductive breaking). In this sense there is no difference between building CC on a train or somewhere else on the power grid. This means you waste energy in this inefficient process of filtering molecules with a concentration of 420ppm which makes only (ONLY) sense if your complete energy grid is already green and you have excess energy or you have only locally available excess energy that you cant get rid of. But it is also inefficient to have a bunch of CC systems around the world, waiting for that solar/wind spike to turn on.
This might be a unpopular opinion, but having oil companies buy and sell captured carbon is far, far better than the alternative. If they can get to net neutral, this solves a huge number of problems. This can effectively bankroll and accelerate the technology.
Another problem with storing co2 in underground caverns, esp ones created by oil and gas drilling and fracking, is that you can't guarantee an air tight seal and that some of the highly pressurized co2 you put down there won't snake it's way back to the surface and atmosphere through channels of cracked and fractured rock
The natural gas we extract today stayed underground for millions of years. It's pretty stable down there actually (if you select the right places of course)
Couple this with carbon credits and it’s even worse. Can you look at how forestry is pushing carbon capture through storage in trees that become timber? Doesn’t that just delay the release until the building gets renovated and the wood ends up in a landfill?
Carbon capture of any kind is a dead end. It's a very energy intensive process and it produces way more CO2 than it captures if you fuel it with fossil fuels. If you do it with renewables, you're wasting energy that could go at replacing a fossil fuel source in the first place. And think about it, CO2 concentration is ~420 parts per million. This means that to reduce it to pre-industrial levels (280 ppm), you would need to process, assuming a 100% capture rate, 33% of THE ENTIRE ATMOSPHERE'S VOLUME. And that's not even taking carbon sinks like the ocean into account. Can we stop talking about this idiocy already and work on real solutions?
"There's no such thing as a free lunch." Meaning to say that, while this train concept does sound technically feasable, I wonder about the overall impact. Wouldn't it have a bigger impact to use this energy to regenerate electricity back into the grid it got its power from in the first place. Thus having overall more electric power available. Power which may have otherwise come from fossil fuels (FF) themselves or replace it where a FF power source would otherwise be needed. While we eventually need to remove co2 from the atmosphere, currently the MUCH larger concern is to avoid it entering the atmosphere in the first place. I don't know where the turnover point is … but at the current rate, we're decades removed from it.
Did I miss a joke? Trains do not magically accelerate with no energy... to power 20 houses from regenerative braking would require using 20 houses of power to first accelerate the train!! Why do we even have the train?? Just power the damn houses with a solar farm??
The fact is the oil companies aren’t disappearing and they have the knowledge to make a lot of this stuff work. I have no problem with then turning a profit to sequester carbon.

The train idea hurts my mind as it's generally a transportation system that runs on fossil fuel, and the energy is not "free", as the added weight ends up taking more energy for the train to accelerate, and then you have to factor in the percentage of runtime that actually involve braking, which shouldn't be often as this is a train. Not to mention that the size of each unit is so small, it's hard to imagine it making an impact. Every little bit helps I guess.
Also the drag created by the air scoops would increase the power needed to move the train right?
Also, the energy gained by breaking could instead be used to power the electric train engine, making the train use less energy from the grid, making it easier tostop using gas to generate enough power. Regenerative breaking is a good idea in it self, does not need a shiny co2 capture thing.
I hope I can explain with an example.
You move an empty train to a mine up on a mountain. The train needs some energy because he needs to move his empty weight up the mountain.
Things that fall down have energy. The heavier it is that falls down the more energy.
Now you fill the train up with heavy iron ore. You didn't need to move the iron ore up the mountain because it was produced there. The train is now much heavier, so if he moves back down the mountain, he will produce more energy than it was needed to drive up.
You harvest the energy with the "extra energy" of the cargo with your brakes.
This is a system that is already used in many ways, but I doubt it would be a good idea to use it as said in this video because you don't speed up to use your brakes just to "get energy".
@@joggetur Haha, you are assuming they drive electric like a developed country, but 99.45% of the U.S. rail network is not electrified!
this idea actualy hurts more than it helps lol, pure hopium!
Very dissapointed about this topic. I've never heard of this "solution" but I can find a lot of problems with it in 10 seconds. First, you will increase the train air friction (no such things as free energy, remember?). Second, if you do recover the braking energy, use it directly on the purpose of the train - transporting (hybrid locomotive for diesel or put it back into the grid for electric ones). Third, do not attempt to suck CO2 from normal air (remember what ppm actually means) and apply this (heavy) machiery near a power plant that emits CO2 like crazy, and at the same time you dont't have to move the weight of this carbon capture device, but rather move... people and goods... This is what trains are for, not for catching molecules of co2. Etc, etc. At least, at the end of the video you mention REAL solutions for ccs - trees.
Even there, they were wrong. So long as they are replanted, harvesting trees is a great way to sequester carbon dioxide.
Trees die and decay though. It's just kicking the can down the road.
Lol they think they have free energy 😂, They are ignoring the solar panels are useless and all the energy comes from an old school diesel engine, Not even a deltec.
Trees die, decompose and pump back CO2 into the atmosphere.
The only real (theoretical) way of reducing CO2 is using nuclear energy to transform CO2 into other stable fluid or solid forms of carbon chemicals, and store it safely somewhere where the carbon won't escape back into the atmosphere after a few hundred/thousand of years.
Either way, the most energy-intensive trains don't brake all that often. Freight trains travel point to point and don't usually stop. The ultra direct high speed service from, say, Barcelona to Madrid only accelerates once (at Barcelona) and maintains its top speed uninterrupted until Madrid, where it decelerates once on arrival. You're not saving that much energy.
Trains don't have regen braking because it's this huge solution, it's just that fitting regen to an already existing electric motor is so easy and cheap that it's convenient for that little kickback you get from the power company.
How did this get past QA? This will produce more CO2 than it captures.

I don't know who came up with the (stupid) idea that trains have a surplus of energy.
any energy recuperated from regenerative breaking should be store back in batteries in order to move the train and reduce their energy consumption (same way it is used in electric/hybrid cars).
solar panel are nice, but their *average* (daily) output is about 100 watt per square meter. even if you completely cover the train with solar panels that is about 5 horse power per train carriage, so no energy surplus there either.
Exactly,

It's even a more stupid idea than that! Why wouldn't you just use the energy captured by regenerative braking to help in re-accelerating the train itself and save on the fuel required, thus not produce as much CO2 in the first place? That would be MUCH more efficient than all the BS being spewed here!

Wouldn't the braking energy be better used to propel the train? Trying to do it on the train will only add to weight and energy needed to accelerate it. The fan is not the energy intensive part of the process so putting it on a train is less efficient.

I don't understand why you claim that this would not require energy to push the air through those train carriages, 'because they're already moving'. Wouldn't such a car increase drag, forcing the engine to work harder, thereby requiring more energy?
Many magnitudes more energy can be recovered than is indirectly lost due to drag forces placed upon the train from aerodynamics, rolling resistance, and mass acceleration.

It would probably be better for the environment for the trains to use that energy to charge a battery to help power the train, rather than to use it for carbon capture, which has always been a technology that has been not been worth even the energy cost, let alone all the other costs.
Yeah that's definitely a better solution. However, it can be used in existing trains which is significantly cheaper than replacing the entire world's fleet of trains with an electric alternative. Hopefully it's used as a transition technology and an excuse for people to stop moving to electric altogether.
@wW-ns6uu I don't think it would be. Something that is always better than carbon capture is just paying to reduce your carbon emissions, dollar per CO2 reduced, has always been better and probably will always be better. CO2 capture technologies are literally sponsored by oil and coal companies to make people feel less bad about using their products.
You are aware that the very people that say carbon capture is impossible now said EVs where impossible 20 years ago right? Predicting what will be possible in the future believe it or not is still guesswork, it’s not breaking any laws of physics. And more importantly we want it to happen
@@josephsalomone there is so much independent research regarding electrochemical CO2 reduction now because it is one of the few tangible technologies that can reduce atmospheric CO2. The thing is - we will always probably need fossil fuels e.g.aviation, steel production. The technological world where we completely stop using them is so far away compared to the rate we need to reduce CO2 emissions. Even if this application is kind of stupid (and this video does a terrible job at explaining CO2 capture tech - it's poorly researched) it is something worthwhile implementing in other applications.
@wW-ns6uu We do not need fossil fuels for airplanes nor for steel production. There are eco-friendly ways to make steel, and several steel mills are already carbon-free, also known as green steel, and while no one is building them or even researching them, much like green energy is the 90s, many proof of concepts of eco-friendly planes exist. Seems like a pro-oil argument you got there.
Dollar for dollar, carbon capture just does not make any sense. It is why no company that is serious about being carbon neutral is making these. Power companies know it is cheaper AND more effective to just switch to green energy as fast as possible rather than to even bother with carbon capture.
The science behind carbon capture isn't great either. Yes, it is possible, but CO2 is only 300 to 500 ppm, 0.03% to 0.04%, and we want to reduce it to 100 ppm. The numbers are just too low for the tech to ever be effective, and the idea that some building size capture facility on the ground is going to remove CO2 from the upper atmosphere is ludicrous.
Thermodynamics: am I a joke to you?
Pretty handrawn pictures: Yes
/s
Immediately suspicious of anything that claims to have no waste energy. Literally impossible to get something from nothing or to halt entropy.
You are absolutely right. However right now on every diesel train in the world, this regenerative braking energy (called dynamic braking in rail) is completely wasted by passing it through large resistor grids mounted atop the locomotive during every stop or deceleration.
Even on electrified lines, if the transmission losses of supplying the regenerative braking energy back to the grid exceed the drag forces of the car, it is advantageous to perform direct air capture on-board the train. This point occurs over fairly short distances given the *realitively* low transmission voltages of catenary lines (e.g. 3-15 kV).
Also, many magnitudes more energy can be recovered than is indirectly lost due to drag forces placed upon the train from aerodynamics, rolling resistance, and mass acceleration.
We would also be happy to show you exactly how meaningful Rail DAC can be. The global rail system has the advantage of being very well established and very, very enormous.
@@co2railOk. . . but why use the energy captured by regenerative braking for carbon capture? Wouldn't it make much more sense to just use it to help re-accelerate the train and thus cut down on CO2 emissions from burning diesel to begin with???

The biggest lie about carbon capture is that it would somehow be more efficient than using the energy generated to replace combustion engines.
@@oz_peter you haven't really said anything relevant
We should be pushing nuclear power now, it’s the cheapest most efficient way to produce energy with the smallest carbon impact.
Not true, used Google and did the math. Carbon capture is a more efficient use of renewable energy than using the same renewable energy to 'replace' fossil fuels in daily electricity generation. (Efficient in the sense, more CO2 removed per kWh)

The fact that every advancement made to clean up this problem is used by the oil companies as an excuse to just keep drilling is a real kick in the nuts.
Think of it this way: no one would use carbon capture unless it makes them a profit. This is a great way to make carbon capture commercially viable at least initially until the technology has matured enough to be widespread
Almost as if global warming is not a technological problem, but a social problem 🤔
The framing of climate change as a technical "Problem" rather than the destruction of society embedded and inherent in capitalist growth and the othering of nature is part of the reason we are where we are.

It's better than nothing. Even storing them in empty/abandoned wells helps offset what was taken out.
This entire train makes complete sense once you start with the assumption that perpetual motion is possible and entropy doesn't exist.
You just made my day XD
But you know what they say about assumptions?
This video is for people who glue their hands to the road.
The reason why carbon dioxide is stored in petroleum reservoirs and not inside rock formations in Iceland, is due to the reservoirs containing oil and gas have tight seals that make sure the CO2 does not escape (The oil and gas would have escaped millions of years ago if these seals did not exist). You cannot store it in random rocks, as the porous structure and fractures in the formations will cause the CO2 to leak back out.
I think there's something about the volcanic rock they're using that chemically binds the co2 so it's locked in and not what is essentially tons of tiny co2 balloons that can be popped to let it escape
The CO2 litterally turns to stone within the basalt in a couple of years. So exactly how could it escape?

Agreed. It would be nice on paper, but I can’t see trains, especially since public transportation isn’t being utilized enough, ever contributing much to carbon collection. Also wouldn’t trains use more co2 from energy than the co2 that they would take out of the air?
The amount of carbon that is captured is beyond negligible.
That's what I am thinking.
You could say the same about not taking a flight, or using an electric car. The point isn't about how much we capture today, it's about how much we could capture at scale as the tech improves. Without it, we will miss our targets, so you better hope it works.
@@hamsterminator the issue is, it doesn’t yet exist on a workable scale, and may not exist before we reach the tipping point of climate breakdown.

I suggest you think about this question. Are electric cars here to save the planet or to save the car industry? We've had a viable solution to reducing car emissions for decades in the form of human centric walkable cities with public transport. Electric cars don't actually save a whole lot of emissions. Maybe 50% over the life cycle of the car. (Ebikes are the new tech everyone should be excited about, they have MPGe in the thousands and use 1/10 the resources of an electric car). Yes in isolation EV's are a good technology and it will have specific use cases in the future BUT it distracts from the problem of car centric cities and car centric culture. If you have an electric car that saves 50% of the emissions but you sell 3x the number of vehicles you have made your problem 50% worse, this is the trajectory we are currently taking.
This video highlights one of the biggest issues with the effort to tackle man-made climate change (besides uncooperative governments): over-reliance on 'new technologies' instead of, you know, getting corporations to cut down their emissions in the first place. Too much attention is given to startups with tech buzzwords and fancy CGI promo videos of futuristic-looking pods while factories and such continue to pump out greenhouse gases unaffected. We have to be tougher on corporations (and associated billionaires).

Wow my head hurts... You guys ever heard of a thing called 'thermodynamics'? This will never work.
Would like to see a breakdown of the feasibility of such a train (if possible).
I doubt feasability is very high. Electric trains already return the energy gained from braking back into the grid. I once had a talk with someone from the swiss rail company (SBB) and he said that on average, for every three trains going down a hill, one could go up for free simply by the energy recovered from braking.
On those electrified networks you don't gain a lot by using that energy to power carbon capture technologies because you now lose the energy recovery into the grid, and have to make up the difference by supplying more energy from your generators. Also if they use the energy from braking to power carbon capture cars, it looks like they only capture carbon when the train brakes, and modern commuter trains brake much faster than a freight train.
In the end, I think this technology may only be viable in banana republics that run non-electrified networks *cough* the US *cough* but also can afford said train cars. And in those situations, you may need to evaluate whether this even offsets the diesel burned in the locomotive, or if it would be better to electrify the network instead.

Perhaps this would work if you power the train via a perpetual motion generator!
You do realize that Iceland is seismically active. So carbon being stored underground in Iceland isn't a very good idea as all it would take is the the mid-Atlantic ridge to form fissures to rereleased that captured carbon.
Also, plants aren't the answer either. Plants are carbon sinks, however, it is a slow, temporary sink. Trees cannot actively remove carbon from the air, but use a passive system. Also, photosynthetic plants require sunlight to convert carbon dioxide and water into sugars and oxygen. However, when they cannot get that sunlight energy, the process works in reverse because it is easier to get energy from sugars and oxygen (which is how most animals on the planet survive).
Not to mention that when plants die and are eaten/decomposed, CO2 is released again. Plants only sequester CO2 when they're alive.
Carbon capture doesn't even work when you are doing it directly at the emitter.

1.Right now on every diesel train in the world, this regenerative braking energy (called dynamic braking in rail) is completely wasted by passing it through large resistor grids mounted atop the locomotive during every stop or deceleration. The amount of energy that is wasted every year is enormous and equivalent to over 100 Hoover Dams.
2.Even on electrified lines, if the transmission losses of supplying the regenerative braking energy back to the grid exceed the drag forces of the car, it is advantageous to perform direct air capture on-board the train. This point occurs over fairly short distances given the *realitively* low transmission voltages of catenary lines (e.g. 3-15 kV).
3.Many magnitudes more energy can be recovered than is indirectly lost due to drag forces placed upon the train from aerodynamics, rolling resistance, and mass acceleration.
4. There is a fairly simple calculation that anyone can do that will show that what we are doing is about 500% more effective from a carbon mitigation perspective than using that same amount of stored regenerative braking energy for additional propulsion. Happy to provide the equation if you are interested.
5. Our research paper was authored by some of the best in the field from such institutions as MIT, Princeton, University of Toronto, and University of Sheffield.
6. Everyone loves trees. Yes we should plant more. However, to do what needs to be done, it would take a land area approximately the size of North America. Must be aerable land, too. Then there is the fire issue where the stored carbon is released right back into the atmosphere. Trees, unfortunately, will not get it done.
7. We are not funded by oil and using our captured CO2 for Enhanced Oil Recovery is prohibited in our Code of Ethics. We simply will not do it.
8. If we do not quickly decarbonize, no amount of direct air capture will matter and it is a complete waste of time and money. However, once we do decarbonize, DAC can bring atmospheric CO2 concentrations back down to pre-industrial levels.
We would be happy to show you exactly how meaningful Rail DAC can be. The global rail system has the advantage of being very well established and utterly enormous.
Love the questions. Happy to answer more.

"it would take a land area approximately the size of North America. Must be aerable land, too. Then there is the fire issue where the stored carbon is released right back into the atmosphere. Trees, unfortunately, will not get it done." Could you provide a source for this statement?
2. If we're willing to put all this effort into inventing a new type of train, surely we could instead invent train lines that could better transfer the braking electricity, or a battery to store it?
3. What's the math behind this?
4. Please provide.
5. Irrelevant.
I am shocked that @asapscience did not upload or correction statement nor even bothered to answer the comments. Thunderfoot uploaded a video about the topic, of course. But the comments here already mentioned months ago how stupid the carbon capturing train is.
Confused european: Why the heck would you want to carry around a CCS system when you can just put the energy back into grid ... "As a result, electrified rail is currently used on less than 1 percent of U.S. railroad tracks while electricity supplies more than one-third of the energy that powers trains globally."
Oh THATS why!
We're doomed if people think a carbon capture train is anything but pure stupidity. I thought this was a science-based channel. I was clearly mistaken. Is it April Fools Day?
Was this posted on April First? It makes no sense. None at all. Absolutely ZERO.
Dude, have you not heard of the second law of thermodynamics... None of this makes sense...
You seem like the kind of chap that'd be interested in buying my hamster powered perpetual motion machine...
Thunder! Thunder! Thunder! ThunderF00t! Hoooooooooo!
Those trains already return the energy they get by breaking back to the grid (inductive breaking). In this sense there is no difference between building CC on a train or somewhere else on the power grid. This means you waste energy in this inefficient process of filtering molecules with a concentration of 420ppm which makes only (ONLY) sense if your complete energy grid is already green and you have excess energy or you have only locally available excess energy that you cant get rid of. But it is also inefficient to have a bunch of CC systems around the world, waiting for that solar/wind spike to turn on.
Not to mention you spend energy *moving* your carbon capture system around along with whatever else the train is carrying
I feel like passive systems would be more ideal. Put wind capture on top of sky scrapers or wherever wind farms are located.
Obviously. It's how trees do it, lol... We just can't learn from nature.
Why is this video still up?
Thunderf00t sent me 😂
BUSTED!!
this is so dumb that I'm suspecting it's psyops by oil companies
This might be a unpopular opinion, but having oil companies buy and sell captured carbon is far, far better than the alternative. If they can get to net neutral, this solves a huge number of problems. This can effectively bankroll and accelerate the technology.
Another problem with storing co2 in underground caverns, esp ones created by oil and gas drilling and fracking, is that you can't guarantee an air tight seal and that some of the highly pressurized co2 you put down there won't snake it's way back to the surface and atmosphere through channels of cracked and fractured rock
lol tin foil hat much
The natural gas we extract today stayed underground for millions of years. It's pretty stable down there actually (if you select the right places of course)
@@augustintommasini7389 since we are now fracking everywhere, not many stable places will be left.
@@augustintommasini7389 that's because they were sealed... once you drill to get to them, you've cracked open the seal.
Pro-tip. Don't trust people who don't know what they are talking about yet sell it anyways.
BUSTED!! by a real scientist called Thunderf00t.
Couple this with carbon credits and it’s even worse. Can you look at how forestry is pushing carbon capture through storage in trees that become timber? Doesn’t that just delay the release until the building gets renovated and the wood ends up in a landfill?
AND THERE IS THE THUNDERCLAP!
Carbon capture of any kind is a dead end. It's a very energy intensive process and it produces way more CO2 than it captures if you fuel it with fossil fuels. If you do it with renewables, you're wasting energy that could go at replacing a fossil fuel source in the first place.
And think about it, CO2 concentration is ~420 parts per million. This means that to reduce it to pre-industrial levels (280 ppm), you would need to process, assuming a 100% capture rate, 33% of THE ENTIRE ATMOSPHERE'S VOLUME. And that's not even taking carbon sinks like the ocean into account.
Can we stop talking about this idiocy already and work on real solutions?
There are so many bad takes I don't even know where to start.
Hmmmm Goggle search: how much carbon is generated by carbon capture?
"There's no such thing as a free lunch."
Meaning to say that, while this train concept does sound technically feasable, I wonder about the overall impact.
Wouldn't it have a bigger impact to use this energy to regenerate electricity back into the grid it got its power from in the first place. Thus having overall more electric power available. Power which may have otherwise come from fossil fuels (FF) themselves or replace it where a FF power source would otherwise be needed.
While we eventually need to remove co2 from the atmosphere, currently the MUCH larger concern is to avoid it entering the atmosphere in the first place.
I don't know where the turnover point is … but at the current rate, we're decades removed from it.
I think AsapPseudoscience is a more suitable channel name for you.
Did I miss a joke? Trains do not magically accelerate with no energy... to power 20 houses from regenerative braking would require using 20 houses of power to first accelerate the train!! Why do we even have the train?? Just power the damn houses with a solar farm??
The fact is the oil companies aren’t disappearing and they have the knowledge to make a lot of this stuff work. I have no problem with then turning a profit to sequester carbon.
When I was a kid, I used to wonder why we aren't doing anything like that. Apparently it wasn't feasible
Me too lol
and still isn’t. this video is pure sci fi and cgi
