14. is insufficient.
Just “putting aside 50% of land and oceans” will not preserve their biomass, biodiversity, ecosystem function, or climate services unless these are actively regenerated.
Regeneration of high biomass, high productivity, high biodiversity ecosystems is essential to restabilize CO2 at safe levels, and that won’t happen if we just continue to kill them through our mismanagement of land, water, air, and ice.
Active Geotherapy of entire ecosystems is needed, the methods to do so are established, but hardly used.
They will be needed whether or not a Geoengineering deus ex machina can be found to minimize climate overshoot.
If we don’t do so, it will happen naturally over millions of years after we are gone.

Do you have a view on Michaux's argument
that the low EROI of renewables is such that there aren't
enough metals in the ground to build a renewable energy
infrastructure to replace fossil fuel, at least not with
existing technologies? And that recycling is not
thermodynamically viable at scale.

Dan
Thanks for the ambient carbon link, which mentions using Cl2 which splits in the presence of light. It produces HCl (and CO2 and H2O), and each Cl atom removes one methane molecule. (BTW we’ve known David Miller several years.)
What we have been proposing for the atmosphere is using a photocatalytic cycle, in which each chlorine atom gets recycled many times to remove many methane molecules – we estimate around 1000 with our latest proposed aerosol formulation.
Solar PV and renewables
I wonder what the embedded CO2 is in this cheap solar PV? China appears quite happy to install ever more coal power for any of its manufacturing.
RethinkX seems to think any location is suitable for renewables, which doesn’t seem credible to me for places that are not very windy or sunny. The cost of transmission then becomes a constraint. The mining of ever lower grade ores to satisfy renewables’ (and the associated grid’s) voracious appetite for resources per unit of energy generation capacity looks ecologically damaging to me, not to mention a health hazard to those who live nearby or work in the mines.
Moltex Energy foresee a future complementing renewables by peaking during the troughs. They have no fear of their power stations becoming stranded assets. They also don’t see the (for now) declining cost of lithium batteries threatening their GridReserve heat storage. Other storage types maybe. But heat storage in nitrate salt tanks is cheap, and they’ll just replace those with whatever becomes cheaper.
But whether a mix of energy sources, or renewables wins out it’s good news if energy becomes cheap all around the world, because that ought eventually to enable the politicians to enact carbon pricing to phase out fossil fuels. That is the important point here.
But let’s not hold our breaths, and not forget the need for immediate cooling of the oceans.

scenarios, where scenarios are assumed futures. The $0.03 kWh
natural gas scenario at $94 per ton removal used the cheapest
fracked gas at the time. Using a renewable energy scenario,
Keith's costs are about 66 percent less than his published work.

History of Carbon Dioxide Removal
Nobel Prize
winner Carl Linde was the first to remove carbon dioxide from
air. His technology was developed from his refrigeration
discovery that itself was first used in the 1870s to help the
brewing industry overcome limitations on summer season brewing
and beer storage that was plagued by bacterial contamination. By
1890 Linde had sold 747 of his “ice machines.” In 1892 Guinness
contracted with Linde to build a CO2 liquefaction plant to sell
excess CO2 from fermentation. This set in motion the ultra-cold
refrigeration technology that Linde later used in cryoseparation
to distill the components of air into usable products that
included, oxygen, nitrogen, carbon dioxide and argon. The
cryoseparation technology first supercools air to a liquid, then
evaporates the liquid in a tall column where the temperature
rises upwards in the column, condensing individual components at
different temperatures, much like water vapor condenses in
clouds.
Image Caption: The WWII Gato-Balao Class submarines were the first US subs to use the potash process to remove CO2 from submarine air to keep our sailors safe from CO2 poisoning.
Early
20th Century Air Capture of CO2
In 1904 the recyclable lime-potash process was
discovered to separate CO2 from air as a simple chemical
reaction using extremely common potash and lime. In 1930 the
first patent was issued for an ammonia-based process that
used amines to remove CO2 from air. Notable applications
were in submarines in World War II to keep our sailors safe
form carbon dioxide poisoning. Also in World War II, the
Habor-Bosch Process was developed to synthesize ammonia from
hydrocarbons in Germany, mostly for explosives, as the
Allies had cut off the German supplies of guano needed to
generate the ammonia. This process became an extremely
important process globally in synthesizing fertilizers. An
important part of this process is removing CO2 to allow the
formation of ammonia. This CO2 removal process advanced the
state of amine technology for removal of CO2 from air. These
three processes are mature today and represent some of the
most important industrial processes known to humankind.
Their components are widespread in industry making their
implementation into a scaled atmospheric CO2 removal
infrastructure a challenge of motivation and money, not
technology.
NOTES:
Slide Summary: Below are references to the three major, mature carbon dioxide removal technologies, their discoveries and invention and notable developments in these technologies: Cryoseparation, recyclable lime/potash, and amines.
Cryoseparation of air… Carl Linde was a Novel Prize
Winner in 1913 for his refrigeration invention and
advancements in science of distillation of the constituent
components of air (cryoseparation). In 1897, Carl Linde gave
up his professorship at the Technical University of Munich
to found "Linde's Ice Machine Company." This company made
possible one of the greatest developments of the human
culture of all time – summer beer. Historically, summer beer
was contaminated by different warm tolerant bacteria that
fouled the beer. In Bavaria in Linde's early years, summer
brewing of beer was strictly forbidden because of what would
later be understood as bacterial contamination in warm
weather. Linde's refrigerator made summer beer possible.
Linde had sold 747 of his ice machines by 1890. In 1892
Guinness Brewing contracted with Linde to build a carbon
dioxide liquefaction plant. In 1894 Linde began his famous
work liquefying air and distilling it into its constituent
components.
In 1897 Linde was knighted as Ritter von Linde. In 1913
Linde was awarded the Nobel Prize in Physics for his work in
refrigeration and cryoseparation of air.
Potash/Potassium Carbonate… A US patent granted in 1904, described a process for absorbing CO2 in a hot solution of potassium carbonate and then stripping the solution by pressure reduction without additional heating (Behrens, 1904).
Potash/ Lye… Giammarco was the first to patent an activated potash solution in 1955, and there are now a number of such processes - Kohl and Riesenfeld mentions some - they are still widely applied.
Haber-Bosch process… This was an extremely important process developed just before WWI that allowed nitrogen production for use in explosives and fertilizers, with a key part of the process being the CO2 removal. It was a German invention because the Allies controlled all the guano deposits that were the nitrogen source. CO2 is a byproduct of the process and development of removal processes played an important role in advanced amine processes today.
WWII – Lime/Potash and Amines: Keeping our sailors safe from CO2 Poisoning… The history of CO2 removal in submarines begins in World War II… "Air monitoring was by colorimetric tubes, soda lime was used to remove carbon dioxide and oxygen candles provide a source of oxygen replenishment." With the advent of long submerse times with nuclear submarines , amines were used to scrub CO2 from submarine air.

Mention of soda ash and amines…
https://www.sonistics.com/wp-content/uploads/A-Brief-History-of-Submarine-Air-Quality.pdf
Amines… In 1930, Robert Bottoms was awarded a patent for removing CO2 from air with amines. The discovery of amines was first published in 1911 by Kazimierz Funk. Funk was inspired by Christiaan Eijkman work that showed eating brown rice reduced vulnerability to beri-beri, compared to those who at normal milled rice. (Beri-beri is a vitamin B deficiency that causes nerve and heart inflammation.) He was able to isolate the substance and because it contained an amine group he called it "vitamine". It was later to be known as vitamin B3 (niacin), though he thought that it would be thiamine (vitamin B1) and described it as "anti-beri-beri-factor". Amines have gone on to become one of the most important chemical groups in all of industry with processes that include: dyes, nylon, medicines, cooling systems, surfactants, cosmetics, agrochemicals, corrosion inhibitor, machining fluids, powder coatings, polyurethane, and epoxy coatings. Amines are a $32 billion industry in 2023.

Hi Dan
I'm definitely outside my comfort zone
here. I'm going to have invest a bit of time and intellectual
energy in getting to grips with all this stuff. My natural
inclination is to resist suggestions that we have access to a
bottomless pit of resources My guess is that we will have to
tailor our wants to match the available resources. But that
implies that we will have to forego some things because the
resources will not be available in sufficient quantity or
quality.
I really struggle to imagine a world in which there will be sufficient resources to enable all 8 billion and more to enjoy the same or better standard of living enjoyed by today's better off. Unending material growth on a finite planet just doesn't compute for me. I haven't yet considered plundering other planets' resources to keep our Earthbound dreams coming true. But I also know that the devil is in the detail.
I also wonder whether the full environmental and social costs of acquiring these future resources has been factored in or whether yet again, we're assuming that the cost of these raw materials is limited to the engineering cost of extracting them.
On a pedantic semantic note, am I alone in really being annoyed by the now very common practice of referring to reducing things by multiples of themselves? If we reduce mining by 500X, wouldn't we end up with -499X as much mining as we now have, i.e. we'd be busy refilling all the pits? What's so difficult about saying it'd be reduced to one five hundredth of its present amount or by 99.8%? I put this in the same category as that awful expression about 'not disagreeing', which, when deconstructed, means absolutely nothing. I know, this is my problem and somehow I need to deal with it! 😉
See comments in red below. As a general
observation, I'm very wary about the Promethean assumption that
there's a technological fix for all our problems.
Robert
If Michaux was right, oil production would be rapidly declining now because of peak oil. Why couldn't it peak and stay ythere rather than declining? There's a difference between the resource being exhausted and it being abandoned n favour of successor materials.
For every one ton of lithium we extract, we extract 50,000 tons of oil and 100,000 tons of coal. So what?
As others have said, if we move from a fossil fuel to a renewable-based economy, we would reduce total mining by 500X. It’s hard to comprehend the scale of fossil fuel mining. Renewables are mined once, provide energy or energy storage for 20~30 years, then recycled. Fossil fuels are mine it, use it once, start over. I think the point that Michaux is making is that the physical infrasture required for renewable that provide the same amount of usable energy as fossil fuels currently do, requires more raw materials than will be available. He also says that the amount of recycling is much l;ess than the rhetoric would have us believe. I find your comment about about fossil fuels (if I'm correcting your typo correctly to the effect that you're saying that fossil fuels are single use resources) is misleading because what you should be comparing is the production infrastructure, the oil well, the coal mine, to the solar panel and wind turbine installations.
Lithium is abundant, cooper is getting less so, but we will figure out how to find more or replace it. Same for the other components such as sand, iron, etc. Obviously if sufficient individual resources are no longer available we will have find more or replace them. It is an article of faith that resource constraints will never hold back 'progress'. It is probably wise not to approach these issues in a reductive manner.
For example, it is often said that hydrogen electrolyzers can’t scale because there is literally not enough iridium in the world to build more than a small amount. But companies like Ecolectro have figured out how to build electrolyzers without using rare metals. Great, but that doesn't mean that every shortage can be magicked away by innovation. I'm not familiar with what Ecoelectro are doing but I'd need to be satisfied that they were factoring in all the costs, including the indirect environmental and social costs, of whatever their innovation enatils.
I do not find a link to a “20-point plan” that is being praised. Please provide the link.

As some of you have said today in emails, we are stalled at reducing emissions because the fossil fuel companies appear to own most politicians (all the Republicans and some Democrats in the US) and they have assumed way too much power during the COPs. Also many people (again, at least in US) don't want to change anything (diet, their gas cooktop, how much they drive), which slows things down. We have not yet reached the social tipping point at which enough people DEMAND change of the politicians. However, I do not think that is very far off. Even with their problems, however, the UN IPCC should be in charge because they are TRYING to give all countries a say and to invoke our "better angels" (rather than allow us to marinate in our own self interest all the time). I believe Oswald suggested an international panel like the IMF, with regulations, to replace the UN. I think such a panel would be instantly bought by the fossil fuel companies and they have certainly done a great job at making sure they are subject to few regulations. We need some democratizing force to remind us that we are all in this together. In general, human societies in the Western capitalist tradition appear to run on self interest and the belief that the Earth's resources are there for us to use. If we can't get over that, we will be among 99% of all species ever to have lived on Earth to go extinct. The Earth doesn't need us.2. I have been reading a lot of the work from the Rocky Mountain Institute, particularly their "peaking" series, in which they analyze how the learning rate for wind and solar has dramatically sped up deployment by dropping the price (https://rmi.org/peaking-the-series/). Those papers have been a real education for me. In fact, RMI is pretty convinced that globally, we have reached peak fossil fuels (though not in some countries like China and India). They are not alone in this viewpoint, or in the opinion that the rapid fall in the price of wind and solar will soon cause fossil fuels to be more expensive than renewable energy. They also have a hilarious table in one of the reports outlining how for every energy/tech transition, the incumbents ridiculed the inventors or proponents of the new. We hear that all the time now about renewables, electrification etc. Incentives from the miraculous Inflation Reduction Act here in the States with its $367 billion for climate solutions is also really helping speed the deployment of wind, solar, batteries.3. Clive, I think your concern that we won't have enough minerals for the renewables we need is a bit overblown.a. Yes, there are problems with mining and communities are being hurt by this, particularly in countries like DRC that care nothing about child labor. BUT, consider the environmental and human damage done by coal mining - both in the UK and the US (probably everywhere else too). Ditto, oil drilling, particularly offshore, and drilling/fracking to obtain methane. The impacts of all those on health and the environmental destruction they've caused in the US are shocking. Recycling used panels and wind turbine blades is coming along, and I don't see how Dr. Michaux can say recycling is thermodynamically impossible. See below, but I wasn't able to find his argument about that in any written form.b. More on Michaux -- I don't think that a YouTube interview is the best way to transmit scientific information so I looked him up to find what he's written about it. I was unable to find any peer-reviewed articles about this. Apparently some of his mining conclusions are in a report to be released from a company/organization named SEB, but the link was broken. Then I saw his technical report about the same thing and scanned the summary. He appears not to have factored in the key information that we don't need to replace ALL the energy in fossil fuels, because so much of the energy is lost as heat in power plants (up to 60% lost) and internal combustion engines (70-80% lost). When we have clean renewable electricity, there's no loss from burning or changing states (as in hydrogen, which is why EVs are 2.5x more efficient than fuel cell cars). Also, Michaux's data are from 2018, and it is a totally different world now wrt wind, solar, batteries and recycling. Call me an "arrogant academic ass" (it's been done before), but I don't put the same faith in technical reports etc that I do in peer-reviewed papers. I'll trust Mark Jacobson (professor at Stanford and champion of wind,water and solar) for info about renewables WAY before I'll trust Michaux, with his outdated data and non-peer reviewed papers. You might want to check out Jacobson's book, No Miracles Needed, for a ton of details about renewables, or just look up his papers.c. Things are changing remarkably fast. Every day I read about new ideas and inventions for new types of batteries, making green concrete and steel, floating solar panels in reservoirs or installing them over irrigation canals, better ways to farm under solar panels, or how to induce big box stores and warehouses to install solar panels on their gigantic roofs and use the power for themselves and/or sell it for community solar. There is plenty of room for solar and wind without putting it all on farmland, which has been a big misconception. And on and on. Most of this has happened since 2018.d. "Virtual Power Plants" are already being used to save the grid during peak times, and they will dramatically reduce the need to build out a huge utility-scale system of storage batteries for use with renewables. A VPP is a control system that can take power from EVs, solar panels on commercial & residential buildings and various storage batteries, and reduce demand during peaks by communicating with water heaters, building controls etc. For this, people and companies get paid. Sounds like the wave of the future to me, and I like seeing creative ideas surface to replace the old obvious stuff like expecting every utility to need banks of permanent energy storage. Check out https://rmi.org/clean-energy-101-virtual-power-plants/, and https://www.brattle.com/wp-content/uploads/2023/04/Real-Reliability-The-Value-of-Virtual-Power_5.3.2023.pdf. This is huge.4. Concerning Franz' idea about turning methane into hydrogen and soot -- that is NOT an emissions-free strategy, since lots of methane will leak out (or be flamed) during fracking or natural gas drilling, then there's also leakage during transport, storage and probably even during the process. Finally, I suspect that people pursuing this strategy would use methane to power the pyrolysis, just like methane is used for the power required for "blue" hydrogen.Sorry, I'm out of time for this, but I wanted to get a few of my ideas out there.Thanks for inviting me to join the group, Clive.Sara

This is techno pessimism to the extreme.
Global warming is an excess of energy that Thermodynamic Geoengineering breaks up into manageable and beneficial tranches.
Per the attached, the primary materials required to implement this solution, Magnesium, Calcium and Lithium exist in the oceans in multiples of at least 50,000 compared to the reserves on the land. And the oceans contain a 700,000 year supply of Chromium which is required for the metal oxide catalysts that can dynamically split water molecules and capture hydroxyl anions with existing electrolyzer designs and there is twice that available from the land.
Talk about checking out the mouth of the gift horse?
It seems to me you’d rather shoot it?

Subject: Re: [CDR] 20 point plan
I think you are misunderstanding what I am saying. I am not suggesting we can live the same lives we did before and happily go on making more and more stuff. I’m thinking more about a WW2 style of focusing a sizable amount of our resources to fight the enemy: climate change. In WW2, people sacrificed to provide resources to the war effort. But I don’t think that CDR takes away from renewables, though it might take away from 1000s of other things we make that we don’t need. Some examples I gave are cruise ships, Marvel movies, and golf carts, but those are only examples.
My point is that if we choose to go all-in to fight climate change we can do things that won’t happen under the current approach of subsidizing renewables (but subsidizing fossil fuels much more!) and then crossing our fingers and hoping for the best.
It still will be difficult and we may face societal collapse before we get the infrastructure in place. We likely will need to start SRM soon to fight off an AMOC collapse (expected in 20~30 years!) that I describe as the mother of all near-term tipping points.
But my other point is that digging up fossil fuels is a more difficult task than making renewables. All the easy oil has already been accessed yet we continue to spend more and more to find more, including tar sands which is really nasty and expensive to convert to oil. So we can find more cooper, lithium, etc. That will not stop us.
But we waited too long to take action so bad things are happening already and worse is on the way. But if don’t act, things will get much worse than bad, with a collapse of society/civilization sooner than most people think is possible.
If you haven’t seen it, I suggest you watch Paul Gildings 2012 TED talk, The Earth is Full: https://www.ted.com/talks/paul_gilding_the_earth_is_full?language=en
It’s our job to prove Paul wrong. So far he is correct and we are ignoring his message.
I’ll also leave you with a quote from climate scientist Kevin Anderson.

> If Michaux was right, oil production would be rapidly declining now because of peak oil.Michaux's thesis is quite a bit more nuanced than that, Dan. He's a very qualified mining engineer, and he's quite familiar with crustal abundances and resource pyramids. His arguments have more to do with EROI and the cost of mining infrastructure than with resource depletion. I'm not even sure it makes sense to discuss his work in terms of whether or not he's "right". His work is predicated on a set of assumptions, and he's pretty good about spelling out what those assumptions are. He relies on data and numerical analysis to project as best he can what is or isn't feasible, consistent with those assumptions. He arrives at the conclusion that a "business as usual" economy based on 100% renewable energy plus storage will not and cannot fly.One can certainly challenge the assumptions that underlie Michaux's conclusions. In fact, I picture Michaux standing before a class of prospective mining and materials engineering students at ANU and announcing "Here's your assignment class. I've shown that the common assumptions on which our governments have been basing their energy and climate policies are hopelessly at odds with the results they're supposed to achieve. Something will have to change. In two weeks, you will turn in papers detailing what changes to assumptions and goals you think will be needed to allow for a realist solution. Quantitative justification for changes must be given; no hand-waving allowed. Collaborative efforts are permitted and encouraged. Have fun."On Sunday, August 20, 2023 at 2:37:31 PM UTC-7 dan wrote:If Michaux was right, oil production would be rapidly declining now because of peak oil.For every one ton of lithium we extract, we extract 50,000 tons of oil and 100,000 tons of coal.As others have said, if we move from a fossil fuel to a renewable-based economy, we would reduce total mining by 500X. It’s hard to comprehend the scale of fossil fuel mining. Renewables are mined once, provide energy or energy storage for 20~30 years, then recycled. Fossil fuels are mine it, use it once, start over.Lithium is abundant, cooper is getting less so, but we will figure out how to find more or replace it. Same for the other components such as sand, iron, etc.For example, it is often said that hydrogen electrolyzers can’t scale because there is literally not enough iridium in the world to build more than a small amount. But companies like Ecolectro have figured out how to build electrolyzers without using rare metals.What we can’t do is continue to emit CO2 and other GHGs into the atmosphere. We are already passed that limit.DanOn Aug 20, 2023, at 11:40 AM, Robert Chris <robert...@gmail.com> wrote:Dan
Do you have a view on Michaux's argument that the low EROI of renewables is such that there aren't enough metals in the ground to build a renewable energy infrastructure to replace fossil fuel, at least not with existing technologies? And that recycling is not thermodynamically viable at scale.

Nuclear is safe, but it is much more expensive than renewables and takes much longer to install. By the time that Gen4/SMR are available, solar PV will cost $0.01/kWh and batteries will cost a fraction of what they do now (which is 10% of what they cost 10~15 years ago).

The winning driver for climate mitigation is lowest cost, which can Thermodynamic Geoengineering can provide.
