I feel like mostly its a boondoggle. A bridge to nowhere that makes these companies bookoos of money while doing nothing except raising the cost of petrochemical products. We already have a good example of how good stewards energy companies are: coal fly ash slurry ponds. These are used to make coal into "clean coal". Some of the nastiest particulates are captured and stored in giant settling ponds, presumably to eventually be buried. This is a common strategy used by many industries for dealing with byproducts. But the problem with settling ponds is that they concentrate toxic waste, which in the case of coal includes radioactive elements. And these are just earthen damns which can leak, or more disasterously, can be ruptuered and the waste can flood downhill. There are several cases in recent years of highly toxic coal fly ash slurry ponds rupturing in Tenneessee and North Carolina. These have in some cases washed out entire towns (it is unclear if the people were allowed to move back or what the long term impacts were) and at least once a slurry pond located directly beside a river used as a city water source burst contaminating the entire water supply. That wasnt the 1970s, that was 2008. I DO NOT trust that these same companies will suddenly know how to securely store carbon or be willing to put the money in to do it properly when they havnt even been safely storing literal radioactive waste. Also, how are they going to get the carbon to these deep wells with solid bedrock? Transport it by bunker-fuel powered container-ships? Seems more likely they will just toss it down the nearest leaky fracking well and call it a day.

The IRA legislation is attempting to correct the price disparity by offering a $3/kg incentive for zero carbon hydrogen. But at current prices that still won’t bring it to price parity. Without legislation requiring the use of green hydrogen the simple costs will drive purchasing of grey hydrogen. In addition there is a matter of supply. Grey hydrogen is 96% of all the hydrogen produced. So even if you wanted to purchase green hydrogen at 2-3x the cost you will find almost all the supply is grey. So is that enough facts for you to realize that fossil companies are pushing for a hydrogen economy because they know they can trumpet the benefits of green hydrogen but when it comes to reality for cost and supply you will continue coming to them for their fossil fuels to supply hydrogen. Not only that. But they will even benefit from that transition to hydrogen as decarbonizing methane to only use the hydrogen leads to a 40% loss of energy. So for the same energy needs you will have to use 40% more methane then if you had just used the natural gas for energy directly.

Terrific video, more like this please. We'll researched and presented as well as being balanced. Carbon capture - humbug. Simply stop burning things now.

This has been a plan for Peterhead for over a decade. 52% of Uk gas comes ashore at Peterhead. However very little gas is burned there, only around 2% of Scotlands electricity generation. Scotland only needs 20% of this gas annually, the rest goes south. The plan was to pump CO2 back into the gas wells, back down pipes to the same place the gas came in the first place.

Another KZread channel named Climate Town regularly covers this topic in depth with sources and citations. I encourage everyone to watch them. Him being funny as heck is just the cherry on top! He also shows that most of the percentages in real life are much lower than published and the published percentages are cherry-picked in a bad way.

“Just Plant Trees” is a popular proposal that assumes it solves the problem BUT my calc showed that if we planted all the arable land on earth in trees it would not remove a significant fraction of the CO2 Fossil Fuels donate each year. Does anyone have an exact range for how much trees would reduce CO2 by? Much of the CO2 produced IS eliminated by natural means (dissolved by the oceans mostly) but these means are approaching their own tipping points. I use the figure of a 90% reduction in Fossil Fuel usage to get CO2 concentrations to level off but also believe that is too low because it does not take other emission sources into account. Some numbers to use in discussion would be of value.

CO2 to sucrose is about 8:1. CO2 to cellulose is less dense, about 4:1. So for every 1 T of CO2 you need 4T of cellulose fibre to store it. It’s approximate because “tree” isn’t exactly cellulose. Also if the tree isn’t used to displace something like concrete or plasterboard it needs to be buried before it rots or it will decompose and release methane. You’d be better off burying sugar cane, kelp or algae

40% of all worldwide shipping involves transport of fossil fuel, oil rigs and their restocking an personell movement and all other offshore oil and gas movements. Stop burning oil and gas, and you almost half shipping emissions instantly.

I've sequestered carbon by burning waste tree trimmings into biochar and digging it into the garden. It adsorbs fertilizer and water, improves the soil, and lasts hundreds of years. The yield is about 50%, but what escapes is stuff I've grown myself, so it's carbon negative. Growing and burning trees for fuel is just carbon neutral, although you hide the CO2 for a few years.

Can you provide a reference for the 2019 study you mention at 6:36. The conclusions surprise me because you said it covers the intermittency, so I'd love to look at the underlying assumptions.

When you look at the big picture like this, I find it hard to not feel pessimistic about the future. You talk as if we're nearly there all we have to do is just stop using oil, like it's a small task. We've barely even scratched the surface of the level of changes needed to get there and also haven't yet seen any real resistance from people that don't want to change. I'm a regular listener of your podcast and I feel that Robert also doesn't quite grasp how far we have to go. I work as a bus driver, and next year we will be getting our first EVs, but it's 15 out of about 200 buses. I would love an ev and my next car will be one, but most people in the UK don't even drive hybrids, let alone evs. That won't change until better EVs start getting through to the used market, (which I think is starting to happen.) My point is that despite your optimism, and all our hopes, it is going to take a very very long time to change our oil use as a species. The dream of limiting to 2c will never happen, we are going to blow way past that and things will get a lot worse before they get better.

They make 20x more power than the original plants AND the resulting waste has a 1/2 life of 30 years. That’s easily managed. The 30,000 years of just leaving the fuel in storage most certainly isn’t easy.

The depiction of the scale of the problem is excellent (see the video at 14 mins), and yet also really quite depressing. The oil & gas industry, for example, has been injecting CO2 into subsurface reservoirs for ~50 years. With all that learning and knowhow, they still only inject about 20 million t CO2/year, or turning the clock back only 4.5 hours/year 😭

In the Uk Solar and wind will not provide 100% of our energy needs. We don't have enough sunhine hours/land available and the wind is variable or zero. If we are to provide our future needs we need other sources of energy. Nuclear? waste problems and fear of a major accident. The UK is an Island surrounded by predictable tidal seas. Much dearer than wind turbines to construct and maintain, but surely the answer together with solar,wind and energy storage. Also you say the aim is to stop burning fossil fuels? The aim should be to be able to use them with zero impact. Batteries, solar panels and turbines are improving all the time whilst equipment which uses electricity is becoming more efficient. Current methods of cleaning combustion products or storing the waste are not up to snuff yet. There has been no insentive for the oil companies to invest to become a viable clean alternative in the future. The growing production of clean electricity and its use should change that. It would seem insane to me to reduce your future energy options if REAL improvement can be made. Also on the subject of seas and oceans, finding a way to undo the PH changes (caused by soaking up CO2), as well as cleaning plastics and rubbish would greatly help with the abilty of these bodies in reducing the CO2 in the atmosphere and improve the environment for aquatic life.

The time machine analogy at the end was amazing. And very depressing. Excellent video. Thanks.

Out here in West Texas, there are a lot of emissions related to gas flaring at the oil wells. This has always struck me as extremely wasteful since the gas that is burned doesn't even result in energy production. I'd like to see that gas collected and used more productively; however, oil companies probably don't do it because it's cost prohibitive. Unfortunately, I think carbon capture is all just smoke and mirrors. The petrochemical companies just want to kick the can down the road. I think that the effort should not be on carbon capture, but to increase wind, solar and hydro projects to avoid the carbon being burned in the first place.

This is a good description of the different types of carbon capture. I do find it somewhat annoying that the same channel that constantly highlights the trend lines of cost reductions for renewables and batteries doesn't do that here. In fact they take the same approach that many EV detractors take; use issues and costs today and simply say it'll never work, never replace the incumbent technology. But innovation happens when companies invest, when solutions start to be deployed, when competition drives companies to improve their economics. Wrights Law helps demonstrate the effect of this. We actually need these companies to do what they are doing. And we simply shouldn't assume that there will be no improvement in the cost/efficiency of these sorts of solutions over the coming years.

our family have been paying to offset about twice our estimated carbon footprint for 3 years using a company called Ecologi, it doesn't us much and we've worked hard to reduce our footprint too. They say we've removed 99.77tonnes of CO2 with our subscription and have 1,479 trees planted for us. I really hope it's making a difference and it would be great if others who have the means can do so too, and it's not just trees but projects and wind farms etc in developing countries.

An excellent, professional presentation; thank you Helen - such a refreshing change from reviewing yet another unaffordable electric car video!!!

The biggest opportunity BY FAR to capture truly huge amounts of CO2 is letting natural systems absorb it. But that requires land. This is scarce for one reason above all others. The animal ag industry uses 83% of all farmland to produce 17% of our food. The opportunity cost of that wasteful use of land is worth 26GT per year, or 65% of global emissions today. That is why dramatically cutting animal agriculture is the only way that we will get a stable climate.

All life on earth is carbon based. Most if not all plants will respond in yield with increases of atmospheric CO2. Most commercial greenhouses add CO2 by 2-3 times ambient with resulting yield increases. As CO2 levels have increased the greening of the earth has also increased.

This was great. Answered so many of the obvious questions one might think of when pondering carbon capture. Answered a lot for me anyway 👍

From perusing the comments, it seems that many people are of the belief that captured CO2 that's sequestered underground is a sort of "gas bubble" that will inevitably leak back into the atmosphere. Limited by time, the topic of sequestration was abbreviated. In the case of subsurface storage, CO2 is stored in suitable geologic formations where the CO2 is stored in either saline aquifers or depleted hydrocarbon reservoirs. Storage can also occur in other formations where it mineralizes in short order. Other types of sequestration also exist. For example, CO2 can be permanently sequestered in concrete, the production of which is a prolific emissions source. I've long advocated a "silver buckshot" approach to climate change mitigation. Carbon sequestration is part of the mix of solutions that, taken in total, will help us to avoid the worst consequences of global climate change. As Helen points out, we have to stop adding global greenhouse gases to the atmosphere. Otherwise, all these mitigation technologies are like shoveling sand sand against the tide. We must decarbonize as quickly as possible. Easier said than done for sure. But we must.

Good content. I'm so over endless car reviews. Thanks Helen. I do think you under estimate what the natural environment can do to capture carbon, for a start humans don't need to plant the trees as evidenced by Hinewai Reserve, Banks Peninsula, Aotearoa. Just give the land the opportunity to reestablish and the natural processes will "plant the tress". Applies to soils, wetlands and marine environments too. This approach is vastly more scalable than gambling on CCS.

@@dykam Yeah, I should have said increased bio diversity, like limestone is locked up carbon from little sea critters if I remember correctly. Biological systems have done a great job at stabilising the climate in the past... for free and no human effort required. Let's give the biological systems a chance to do that again, nature dutifully working in our favour with zero effort from us just seems obvious doesn't it? We can have our technology on standby for extreme events.

Underrated video, I am sorry the algorithm screwed with this video. Still, CCS is confusing as a subject since it is so broad and so wide. Not to mention the fossil industry trying to push their own take on CCS scam as a viable option.

CCS is a fossil fuel company grift. The cost exceeds the benefit.

Privatise the profit and socialise the costs

Is it bad that I came up with a theoretical scenerio where the Oil in the ground was put there by us in a never ending cycle of climate catastrophy. We discover the oil, we burn all the oil, we realise the damaged to the climate, we capture the carbon, pump it underground, we was too late, most people die from the hostile climate. Hundreds of thousands of years pass, the carbon we put in the ground starts turning back into oil. The survivors start to progress back up the technological ladder and then discover the oil and repeat the process. I suppose it's pretty much the same as nuclear weapons, chances are we would have found evidence if any of this had really happened but it's the same kind of self destruction loop.

Thank-you Helen and team. This is the point, not just about reduction and mitigation but reversal and renewal. After MUCH consideration, assessing my carbon footprint and surprised how high it still was (5.2 tonnes/year) even after car-free cycling life and knowing reducing CO2 is the goal, I looked into a CO2 removal systems which works. The only one I could see with a chance is ClimeWorks. It's not perfect and I've been waiting for over a year to see if someone can fault it but it seems to be valid so far. Expensive, Yes! Small scale,Yes! But it's using geothermal energy to power the system and geologically storing the CO2 so it can't escape in the future, therefore it ticks the main boxes for me. It's been over a year I've paid €50/mth to reduce my CO2 to 4.6 tonnes/year. I wish I could do more but I live in AU so I'm in a system. The main reason I have for supporting ClimeWorks is to see them scale and bring the cost down by one or two orders of magnitude. Meantime I'm continuing to tweak my lifestyle to not produce CO2 where I can. I may have taken my last flight!

Forget trees, fast growing grasses (sea grass and bamboo as an example) are far more efficient at removing CO2 and locking it away.

The plant in Iceland is the most efficient direct from air carbon capture system built to date. If it were scaled up to balance just our current emissions the necessary land would be the size of the State of Texas.

This is different, super cool hope to see more of it!

_Is Carbon Capture An Excuse To Burn More Fossil Fuels?_ Yes.

So once you capture all the carbon, what are you planning to do with it?? We can't keep sticking our waste underground, we need and must learn to or invented technology to not only capture but to recycle in better products or uses.

Absolutely correct. The easiest and cheapest way to mitigate atmospheric CO2 is to not digit up in the first place.

Great episode guys. We forget sometimes that 75% of all carbon emissions come from industry. This is where the biggest effect on climate change needs to happen. Electric cars by themselves will not be enough.

EVs lower local pollution.

Love these types of episodes

BIG OIL should pay for as mush as they produced. That will never happen ofc. What I think will happen is that we subsidize the company's to remove a small % of their own mess, while they all earn even more money. Do what you can, get rid of gas in your house, get an electric car next time you buy one. Support company's that are doing something real for the environment, and not only green-washing.

If carbon capture actually works it would be a great way to allow continued use of oil fuels. The huge snag is that carbon capture does not work. On the plus-side, we don’t need to stop all carbon fuels. The big snag is that any loopholes will be exploited. Ships would absolutely be into that game.

Excuse me but climate change is not the only side effect of oil fuels. The core issue is local pollution that literally kills kids and the elderly. Hence most long living people are from rural communities away from roads.

Please stop burning oil as we need it for manufacturing everything, especially chemistry and composites

although this video puts the CCS into perspective, this kind of non sensical, maybe and soft and peaceful approach is not going to cut it. the oil companies lobbyists are soo aggressive, why should not we be aggressive at stopping them? why do we keep delaying action

Carbon Capture technologies have one big flaw that I can see. Human air pollution creates more than just Carbon Dioxide, it also creates Carbon Monoxide, and other pollutants. So while it is good to reduce the Carbon Dioxide, what do we do about those other pollutants?

Thank you for at least mentioning CCU, although I would have liked it if you elaborated more on it. Big emitter companies don't want to implement CCS because they see it as a net loss in their revenue (and it is let's be honest). However, if they could make something profitable out of the CO2 they capture instead of stupidly putting it in the soil l, they would have way more incentives to do it. Would love to see a video about it in the future

Very clearly explained, and some important food for thought. Wish more people would watch it. Also, we have that same chair 😊

If the Icelandic facility works, why not add an incrementally increasing surcharge to all internal combustion engines and all fossil fuels, to build and deploy more of these plants?

Yes. Eventually the tax on fossil fuels should be raised to the point that it's enough to pay for the same amount of CO2 to be captured. You ate paying to clean up the mess you make. It's only fair.

If the warming gets increasingly significant (enough to endanger coastal cities and low-lying property) ... Then some state actor, whether we approve or not, is going to attempt geo-engineering: Injecting sulphur into the atmosphere. Of all the mitigation methods, it's the cheapest. This is probably not a great idea. But when did that stop human beings acting in their own self-interest?

We won't be able to go without. We do need CCS for industry, As else it fossil carbon they will use. To clean something up that's already expelled we use DCR, wich we will get better at all the time. And yes we need to scale up nuclear and other sustainable sources constantly!

Merci beaucoup for this report. I feel it's not a rhetorical question. Yes, of course it's an excuse. And the IPCC has been captured by Big Oil. Hemp is the only CCT we have that works today, and it can help replace plastic.

Carbon capture takes more energy to take it out of the atmosphere then we got from burning the fuel. We're basically paying for the pasts energy generation with our electricity.

the problem is, the statement we need to make it fast.. no we need to make it right. I work in renewables and have seen what happens when you make things fast to make the projects come on line... Tooo many things break due to lack of proper production. then comes the shipping issues too fast leads to damaged equipment so things have to get made twice. I really feel it is the REDUCTION of usage that everyone needs to do with the slow injection of newer tech and then further the reduction of usage then you can increase the amount of CCS/CCR ideas. I would love to see anything and everything come to be solar on homes, only use ICE when needed, and then get the battery production not using rare metals, and have a good recycling place. I know I said ICE in that, mainly due to it being something to use sparingly. not a daily, but on the weekend at race tracks, for long haul trip for those enthusiasts that like the sound created and the ability to make something with a family member. currently trying to make an electric car or race car with the family is way to expensive and hard to do .. lets use or reuse what is taking up a lot of space with cars currently to keep those enthusiasts going further and slowly adopting when the batteries are better and motors are more plentiful and then motorcycles also can do the same... a slow mythotical plan is always the best so the correct data set can get made to where scaling will be a no brainer, more effective, efficient, and costs will be a LOT less... anyway I look forward to seeing more CCR and CCS happening and seeing how the infrastructure companies can keep up when the oil is not able to be used to make a lot of the products that go in them. cheers.

Great video! You're absolutely right... and yes, there is a big fear that at least some of the CO2 that is pumped into the ground comes back up somewhere else.

Firstly let me state CCS particularly on petroleum production and energy generation projects is pure stupidity. But to your point there is very little possibility that underground sequestered CO2 will return to the atmosphere, other than natural emissions that happen on their own. If the natural gas was not escaping, then neither will CO2 pumped into a reservoir to push out the natural gas and oil. But don't worry, there are so many other arguments against CCS we do not need that one. Best argument is likely that it takes so much energy to do CCS that it produces more carbon than it sequesters. If I said "let's use a huge amount of energy to capture a small mount of emissions from our energy production." Would that make sense to anyone with basic math skills? Not unless they are a petroleum company executive or the politicians they bribe to fund these stupid projects.

Pity no reference to Carbon Capture at sea such as that being worked on by Seaweed Generation. Here they propose taking the excess Sargassum seaweed that has spread due to the discharge of fertiliser into the sea and plagues many beaches and by taking in far enough below the surface that its air pockets burst make it sink to the seabed. Due to the lack of decomposition at the depths involved the carbon in the seaweed should be removed from the carbon cycle for multiple hundred of years, by which time, if humanity is still around, one hopes they would be in a position to deal with its possible slow reintroduction.

Hi Helen Really grateful for your overview 🙏

The CDR facility in Iceland, Orca, cost $10-15 mil to build. Removing 4000 tn of CO2, equivalent to 2 WHOLE petrol cars (average km’s per year with passenger car, gasoline: 9,994 km, source CBS, Dutch National Statistics).

I suppose, you mixed up tons and kilograms. A petrol car will produce around 2 tons (2000 kg) of carbon dioxide per year. However, it's not even a drop in the bucket.

I just can't see any carbon capture method being worthwhile. All efforts should to go towards stopping the burning of fossil fuels, increasing renewables and changing how we move around - basically walking or cycling!

The easiest way is direct CCS where the C02 is not diluted in air and not damaging the planet. The problem is transporting it (via pipelines) to underground sequestration sites that can hold the gas forever. Not many cement works build next to mines not even many cement works are often next to where the mining material even comes from!! As for trees, great idea but you need the landmass of India/etc to plant the trees AND early stage trees do not capture much PLUS trees die and then release their carbon as they decompose. Thats presuming a climate change wildfire or drought does not kill of millions of them first (with the wildfires dumping gigatons in one large fire). How do you capture C02 on a cargo ship or Cruise ship? What about plane carbon exhausts. This is why big oil will love CCS as it can both use it as EOL AND then count that as CCS. Win-Win (for everyone bar the taxpayer/environment and fuel prices).

Great video!

There is no climate problem. There isn't too much carbon dioxide in the atmosphere. Carbon dioxide is the most essential gas in the atmosphere, and it exists as only a trace. If the levels were much lower all complex life on the planet would disappear. Removing it from the atmosphere is hubristic madness.
