Catastrophic Carbon Removal. How the 'Big Solution' is failing badly.

Carbon Dioxide Removal is our only chance of keeping the atmosphere of Earth at a habitable temperature in the 21st Century. That's what our scientists tell us anyway. And they say we will need to remove billions of tonnes of the warming gas in the coming decades if we are to succeed in this ambitious goal. So what is Carbon Dioxide Removal? Why is it different to Carbon Capture and Storage, and how on earth will we do it?

I agree with the gist of what you're saying, "humans as a group are incapable of doing...". Collectively, "we" are inventive but individually conservative. Science & technology advances are readily picked up, mostly through the filter of an outdated brain shaped by equally outdated evolutionary forces. The lack of common language, overpopulation, warmongering, excessive economic disparities and irrationally biased education systems are only but symptom of "our" collective failure as a species whose good luck is running out. I, too, think that trying to improve is important and morally righteous, but I am not optimistic. Eventually, and hopefully before an extinction event, a better intelligent entity will take over the running of the planet, but this will mean that humanity, as we understand it today, will not be the leading force shaping the destiny of our dying planet (dying because over 80% of the theoretical span life can subsist on this space rock, is already gone). This could be, perhaps, the fate of all, or nearly all, of any evolutionary biological intelligence. This "intelligence" is shaped by the complex interaction of ecological constraints and when a successful organism significantly alters them, disaster is a likely outcome. Miniature events of this kind happen in the "boom & bust" cycles of prey/predators populations in unsettled ecological systems, and "we" as humanity are now playing with the whole planet. No other home is available to us to immigrate to, so the magnitude of what going to happen is guaranteed.

[@CplusO2]

Hi Dave, thank you once again. As a soil scientist and 30yr veteran of Australia's carbon wars I would like to make 2 points. Firstly we are at war, the fossil fuel industry profits from war and the fertilizer industry was born from war. Since the earliest days the carbon industry has been targeted as an enemy, the list of dirty tricks is long. My second point is that we have the capacity to store carbon at the scale needed. The state of agricultural and forest soils is heartbreaking. We are also facing what some scientists call phosphorgeddon, where we are simultaneously running out of rock phosphate whilst destroying waterways with too much phosphorus. This is an inflection point, the solutions to climate change are also the solutions to food insecurity. The solutions to climate change are also the solutions to biodiversity loss. The solutions are beautiful and that has to be the message.

[@CplusO2]

@@Monkeyboysdontknow That is a very long answer. Luckily not my solutions but a vast array that offer at least some hope. C+O2 has developed a system to plant trees as fast as we currently plant wheat, which is pretty rocking. Planting trees of course is not enough, we need to get that carbon into the soil. For our part we are working on a Terra Preta project to identify the biological mechanism that makes soil "self replicate" it's pretty exciting stuff. My point about phosphorus is that the global supply is very finite and western leaders seem hell bent on a war which would lock the west out of over half the global rock phosphate supply! The first rule of Empire is that hungry people are dangerous. Using soil biology is the only feasible way to produce enough food without synthetic fertilizer. I would like to note that precision fermentation, particularly from cellulose, mycelium and methanol gives me hope.

[@kimwelch4652]

Our real problem is not a technological one; it is a social or behavioral issue. We have the technology to solve any number of humanities problems including climate change and its cause ecological overshoot. However, as a species we do not have the social capacity to respond in an effective way. You could consider the whole human species to be suffering from an addiction problem where there are no non-addictive support systems to help us stop and no way to clear our system to get sober. That's not even talking about carbon, that's all about the game of wealth and the way it coopts every bit of society's energies. You cannot do anything unless someone makes money off it, and that generally requires subverting the game so the goal is lost. We don't talk about the progress of projects to solve our problem, we talk about how much money we spend or make on them. I've said it before, and I'll keep saying it: As long as we measure our survival in monetary terms, we cannot afford to survive.

It uses solar panels to split water for hydrogen, which is what photosynthesis does to combine that hydrogen with carbon from the air and nutrients from the soil to make our food. But plants only get 6% of the sunlight. The crop must grow and maintain itself, and we only eat part of that crop. Sometimes we eat less than 1% of that incoming sunlight, and it’s often mostly carbohydrates when what we really want is more protein. But now scientists use solar panels to get 20% of the sunlight, and split water at about 80% efficiency for hydrogen so now we’re at 16% of that sunlight. Then they feed that hydrogen directly to hydrogen-eating bacteria, and with a little water and a few mineral fertilisers, it can produce all the proteins and fats we want.

When electric motors came along, it took years before machines were arranged in more functional configurations. In the same way, we are trying to use electric cars like ICE cars, but it would make a lot more sense to use them as smaller, NEV (neighborhood electric vehicles) and use mass transit options between urban centers.

Even if I were to go completely carbon free, it wouldn’t make any difference at all. How can I do more? I think that it comes down to the fact that, as an “average” person, I have very little influence and affluence. However, there are thousands of billionaires on the planet, each with orders of magnitude more influence and affluence than I have, and presumably a much bigger carbon footprint too. Convincing even one of them to go carbon neutral would be a big deal, the equivalent of convincing thousands of “average” people to do so. What if, for instance, Jezz Bezos went carbon neutral? Covering the roof of every Amazon warehouse with solar panels would help too. Doing so would even make him money in the long run. Maybe to make up for past behavior he could also buy a few square miles of damaged Amazon rain forest, protecting it and allowing it to recover and become a carbon sink again. It would make a very small dent in his personal fortune, probably less than he loses on a bad day on the stock market. However, you don’t need to be a billionaire to make a difference. Going carbon neutral isn’t that expensive anymore. How about getting the influential “one percent” involved? What if, for instance, Barack Obama, Taylor Swift, Drake, Graham Norton, Jimmy Fallon, Tom Brady, the Kardashians, etc., etc., etc. went carbon neutral, and told all of their millions of Twitter followers about it? How many millions of them are there, each with lots of money, lots of influence and an out-sized carbon footprint? Even getting a small fraction of them on board would be a tremendous boost to the carbon-free industry. So, how do I do it? How does the average person like me convince billionaires, multi-millionaires, politicians, etc., etc., that something needs to be done NOW, and THEY need to start doing their part?

We have lost a third of our forests to both crops and grazing - 2 billion hectares. It took 9,000 years to lose the first billion hectares - an area the size of the United States. Then in the last 100 years we cut down the next billion hectares! 2 Billion hectares of forest are gone - a third of the world's forests - largely to grow crops and graze cattle. If we eat Precision Fermentation 'meats' instead of animals or fish, we can let those forests regrow and the oceans recover. We only eat just over half the crops we grow - we feed a third to animals and more to industry for jokes like ethanol. When we stop eating meat, we can stop growing a third of our crops - and let that return to forest or grasslands. When we stop the farce that is ethanol crops and use EV's instead - we can return the industrial croplands to forest or grassland. Regrowing the third of our forests lost to agriculture will solve climate change. The maths is simple. At an average of 1,600 trees per hectare multiplied by the 2 billion hectares of forest to be regrown that's 3.2 TRILLION trees. We know just 1 TRILLION trees would sequester a third of our historical carbon emissions. Therefore 3.2 TRILLION trees would sequester it all! Precision Fermentation could solve climate change!

We all need to start adopting UNEP's current stategy to focus on the triple planetary crisis of climate, biodiversity, and pollution/waste. And climate is not an umbrella but sibling, overlapping crisis. Some of these carbon dioxide removal approaches like BECCS, afforestation, soil carbon capture will damage already strained biodiversity and ecosystems and byproducts in a non-circular economy will exacerbate pollution. Simply, we need more nature-based solutions (NbS), consumption pattern and production process change, and not geoengineered or tech solutions. NbS may not be sexy or fast but in long run rebalances the Earth System. We need to restore degraded ecosystems in the current UN Decade on Ecosystem Restoration not more land use changes that have fragmented and destroyed natural habitats. Biodiversity also has its tipping points, positive feedbacks, and accelerating extinction rate trajectory. Let's not be razor focused on climate but on totality of our nature crises!

I could also heat the water "on site" essentially without gas. My aim is to insulate the house as best as possible, making sure that the house is air tight yet ventilated etc.. Essentially following PassivHaus principles Then and only then will I have a heat pump, and move over my cooker to an induction one.

Yeah, it's a little worrying that the only reason DAC is developing is for assisting fossil fuels extraction. But I should remind everyone that fossil fuel companies were helpful in getting solar PV off the ground in the second half of the 20th century with installing panels on offshore drilling rigs, onshore storage tanks, and other equipment and wellheads for remote, microgrid support of critical functions. We'll probably see a lot of maturation here with DAC in the next decade due to those companies. At face value I think this is a bad thing, but the global energy transition will take time. So, while fossil fuel companies will have to search harder and harder for oil and natural gas, trying to prolong the realization that they're sitting on soon-to-be stranded assets, we as a society will get a CDR platform/technology that could be incorporated in many other applications over time.

You hit the nail on the head exactly! I have been researching this topic from the biomass to syngas through gasification for about 20 years. It dawned on me at the time that instead of putting a wood gasifier in a truck bed, have a stationary gasifier and make methanol to put in the tank. The woodgas people I guess couldn't grasp the concept that if you can produce methane, you can produce methanol. It is a holy grail I have been passionately pursuing. I have studied about Mobil Oils MTG (methanol to gas) using the zsm-5 catalyst they accidently discovered. I have read about the oil companies pumping hydrogen into the underground CO2 storage caverns. Over time it produces methane (natural gas) and water, to be later pumped out and turned into gasoline and other hydrocarbons. SO, in conclusion. It smells like a big con job. Tax credits and great PR for investing in carbon capture, maybe some federal taxpayer money to boot. Meantime they squeeze every last penny out of petroleum until they are regulated out of that business. Wow, neverending big corporate (centralized) money machine. THAT'S why I search for the holy grail (catalyst) to decentralize the stranglehold.

[@jeffanderson-lee1574]

Methanol generation may potentially reduce the need for burning new fossil fuels but it does not remove carbon for the air for very long - only as long as you keep it in your tank. And oil/gas companies will continue to drill and sell new fossil fuels for as long it is profitable. Methanol might actually delay the switch to electric or hydrogen which we will ultimately need to kick the fossil fuel habit.

The most hopeful approaches imho are Climate Restoration, using simple technologies such as: 1) Sprinkling tiny amounts of iron particles on iron-deficient areas of the ocean to stimulate plankton growth which in turn creates food for marine life while absorbing carbon; 2) Using beaucoup mirrors to reflect sunlight away from the ocean as being proposed by MEER. The immediate need is to reduce temperatures, especially ocean temperatures, to avoid a crescendo of extinctions of marine life, as well as terrestrial life. At the same time it is essential to rein in the astonishingly high and steady rate of decline in insect life and the similar rate of decline of bird populations.

America could start today, at almost zero cost, by changing farm policy from chemical to natural, and cancelling corn ethanol into fuel. At 1 ton of CO2 capture per acre with hemp cultivation and cover crops replacing most corn & soy, globally, that could easily become a billion tons per year absorbed from a billion acres of farmland. Hemp produces much more protein per acre, and the ethanol corn wasn't eaten. The byproducts of hemp oil & heart production is seed cakes, which is better feed for cattle than corn is. Farmers could make more money, building up soil. That's the research we need from our ag universities. Instead, they're owned by Monsanto & Bayer, who want more (fossil fuel based) fertilizer & more (oil based) chemicals.

You mention how carbon removal by natural means (reforestation mostly) uses a lot of land. I have heard that restoration of wetlands was much more effective than reforestation, allowing for the same amount of carbon removal with a fraction of the land use. Peat-forming wetlands seem to be surprisingly effective at carbon removal because dead plant material does not decay in the same way as a dead tree in a forest would. Instead, the dead plants sink, get cut off from oxygen, and create layers of peat. We have drained a lot of wetlands, but the process is easily reversed. Also, there is the added benefit of the wetlands as buffers for flood water and refuge for a variety of rare species.

The downside being the current animal order will have to change, and there are greenhouse gases involved. Alaska is getting marshier with beavers taking up residence. Iceland will green up. I think we don't have to control the uptake of carbon, it will happen as a natural order, but the problems will come with weather or not humans and current life will be able to stay healthy and functioning as societies. There is almost no indication in my small farming district that anyone other than me is interested in putting in the proven sustainable and regenerative land management techniques that could help direct the carbon uptake in a win win direction...even though our government zoning laws etc support and promote that positive direction.

Restoring such ecosystems also provides the following benefits - mangroves & kelp forests protect the land from the action of the sea, especially during storms - mangroves & kelp forests also provide nurseries for juvenile fish & other species - forests stabilize local climates and manage water (as part of the water cycle) - enhance biodiversity by providing habitat & resources for other plants & animals - provide food resources for local communities - provide fiber & materials for construction, clothing, medicines and other sustainable economic activities - provide amenity & utility for tourism & wellness (people do better mentally & physically in nature) Trees in urban areas (the right kind of trees) provide shade (keeping cities cool during hot summers), calms traffic, helps clean the air, manages water and enhances wellness (especially for children) and property values. It's no surprise that governments prefer the former (concentrating wealth to the well connected few) rather than the latter. What could possibly go wrong?

As you said, pretty much everything we do emits GHG, so if you ask me, we need to rationalise our economy to cut back unnecessary consumption and scale down related industries, redesign products so that they last longer and can be effectively recycled, invest in public transport, redesign our cities and homes and shorten supply chains as much as possible.

I’ve said it before and I’ll say it again. The creation of artificial reefs via electrolysis driven mineral accretion has the potential to store thousands of tons of carbon in each site. Furthermore, it creates new habitats for thriving marine biomes, which in turn will create more seafood that a growing human population will need to survive.

[@jimthain8777]

The problem with that is identifying which politicians, business leader, and others are really serious, and which are selling us a line to get themselves elected, more money, or other goals. This is something that's REALLY hard to gauge. We simply have no clue what these people really think. I've watched many politicians and business people sell snake oil over the last 40 years. Frankly I don't have much faith in our leaders. I believe our only real hope is ourselves. We can do whatever we can to reduce our personal use of fossil fuels. We can't control others, but we can control ourselves. So I do what I can and encourage others to do so too. I do know that if a significant number of 8 billion people all did just a little bit, that would amount to a huge reduction.

Your video on Carbotura was amazing and seems very scalable. I would like to build Agrivoltaics Microgrids paired with those hemp biomass biochar bioremediation systems and possibly replace existing fossil fuel feedstocks with syngas from the gasifiers. Love all your videos and appreciate your dedication. We can do this! The Airminers Boot up free online course and Frontier Climate are excellent resources. The Agrivoltaics solar farm summit 2023 in Chicago was amazing. Really, we can do this. I also believe the space industry will be hugely instrumental in catalyzing the decarbonization of the economy/ CDR. The methane rocket fuel must be made carbon neutral and we must start sending all carbon negative materials into space for offworld habitats and mining operations. Space based carbon removal will likely never exceed a tiny fraction of the total CDR needed but they can advance the industry immensely with the technology needed to fully draw down CO2 on earth. It is a terra forming conundrum we are in.

The thing about carbon removal that requires electricity, it only makes sense when it is on a grid where no carbon is added to the atmosphere. And even if it is, then it only makes sense, if there is nothing that can be moved from a carbon burning grid to this carbon free grid. And in the cases where carbon capture is being used, the carbon is usually used in industrial processes or farming meaning that the carbon goes straight back into the atmosphere. All in all, currently a good old forest is the best way to sequester carbon, whereas mechanical carbon capture may be cool, but there is no use in scaling it up until such time as the energy grid is completely green.

[@jeffreyroberts4637]

It has always been the case, that reaching net zero by the use of renewable energy was only ever going to be half the job, it should have always been clear that we would have to spend the next 50 years removing all the excess carbon dioxide, we had already put into the atmosphere, the big 3 questions are how is this to be achieved? How energy efficient is the procedure? And most importantly how will it be paid for? But first, there is one theory that was very popular 20 years ago, but now seem to have been completely forgotten, even banned, the theory suggested using Iron in a fine powder form to be sprinkled over the northern oceans, which would invigorate the bottom of the food chain phytoplankton, which in turn would use sun light and Carbon Dioxide in a photosynthesis process to rapidly multiple, and whether they were consumed by higher organisms or decay they would take their converted Carbon Dioxide to the ocean floor, it seemed to be a plausible idea to me, and the oceans are certainly big enough to play their part, so what happened? was there a fatal flaw in the scheme? The first of my 3 questions how are we to remove Carbon Dioxide out of the atmosphere? Well letting nature take the lead would be a start, it has been doing this much longer than we have, replanting forests and letting green things grow, but as you have already stated there is a limit on land for such projects, because as a species we need that land for housing and food production, there are other options like growing algae on land then burying it underground, just how efficient or cost effective that would be is uncertain. Then there is the mechanical method, which I believe uses a lot of energy, so there is no point in using a fossil fuel power station to generate the electricity to run such a plant, so we would have to use renewable energy to operate such a plant, but as it stands we are a long way off from having surplus renewable energy for such an enterprise, you can currently criticize what they do with the captured Carbon Dioxide, but I am certain it will eventually be stored in deep abandoned coal mines or similar, and you worry about whether such plants could rapidly be increased, if there is money to be made from it, investment money will not be a problem. then there is the cost, for now companies are willing to buy Carbon credits, but what happens if by some miracle we actually reach the goal of net zero, somewhere close to 2050and even shipping and jets run on some green fuel, nobody will be buying Carbon credits, and we will be back to the arguments over who should pay and who is responsible for historic Carbon Dioxide emissions.

[@SeattleCoorain]

In my opinion your idea to engage phytoplankton is spot on. The Germans experimented with iron sulfate ocean seeding around the antarctic several years ago with modest success. If I am remembering correctly the main disappointment being the phytoplankton benefiting most from iron seeding had the lowest body weight and therefore after expiring lingered too long in upper water levels which caused their lightweight bodies to dissolve releasing the carbon into the water then back into the atmosphere before reaching lower depths where it could remain fixed and sequestered. There was also some iron seeding experiments in the Pacific NW in Canadian waters designed to improve fish habitat for native fishing communities.
