A Modest Proposal For Sequestration of CO2 In the Antarctic

timothy posted about 2 years ago | from the no-salt-domes-in-sight dept.

Earth 243

First time accepted submitter Alienwise writes "Judith Curry reports a scientific concept of an atmospheric CO2 sequestration plant. It would be based in the Antartic to profit from the cold weather, which would facilitate the creation of CO2 snow — which would then be buried. The plant could be powered by windmills." The lead author has agreed to let Curry link to a copy of the final manuscript, if you'd like to read more.

Well, given that most of the newly minted CO2 that we are concerned about is produced by digging up carbon that was swept under the carpet and setting it on fire(with a side of deforestation), I'd say that under-the-carpet storage is a time-proven part of the carbon cycle.

Now, techniques for sweeping it under the carpet without titanic amounts of energy and in less than geologic time... that's still in progress.

I will tell you what I like. I like it a lot.

I think it is great when I have lots of hot farts. You know. The farts that feel warm and hot when they come out your asshole. The farts that stink so bad but to you they smell so good. The farts that can clear a room. The farts that can end a marriage, to use Carlin's words. But no test fart. Oh no, this is the full monty and lots of it!

I work with the general public. I love to let silent farts like this! It makes people leave me alone. When it comes to old people, smellin' to high hell is the ONLY way to get them to leave you alone! Their vision might be dim and their hearing impaired, but by God they can smell. They can smell my farts and leave me the fuck alone, like God intended.

I just wish I could figure out what to eat to have those more often.

Not quite. The CO2 maybe sweeped under the carpet, but if you would actually read the paper, page 21 shows that there may be a significant amount of excess heat produced by the process, which needs to be release to the environment. The CO2 is not the problem. The heat is?

So, in order to combat global warming, we install 400+ heaters on Antarctica? I'm sure the science behind it will work, but my initial response is: uuh... what?

Either way, I simply just don't understand the logic. Antarctica is being threatened by melting ice, and now a scientist (who I'm sure is very intelligent) comes up with an idea to install huge heaters in that area. I'm sure they will remove co2, but won't the side-effects be worse than the medicine?

Chris Mattern (191822) | about 2 years ago | (#41126137)

The amount of heat produced directly by all human activity combined is tiny compared to the heat applied by the sunlight the earth receives. The contribution of all human direct heat production is so small that no large-scale analysis of global heat retention even bothers to include it. Global warming is effectively entirely the result of increasing CO2, which increases the amount of incoming solar heat the Earth retains. Removing significant amounts of CO2 from the atmosphere would relieve global warming regardless of how much direct heat the process generated.

Every time a politician blows hot "air", he only releases heat once. But, it's the CO2/legislation that has the long-term, magnifying effect.

We are saying that the observed variations in the Sun's output in the last 50+ years have had a negligible impact on the Earth's temperature. But we still know that the Sun is essentially the only* source of energy driving the Earth's temperatures and any significant change in the Sun's output would be reflected on Earth.

* The other sources of energy are so small relative to the Sun that they can be ignored in first order calculations.

Um, you do realize that no human activity *creates* carbon, right? It just moves it around; in the case of global warming, we're moving it from in the ground (where it's not a problem) to in the atmosphere (where it is a problem). This moves the carbon back into the ground. How does that not work?

Err, actually no, the reason we're in this mess is because CO2 is a by-product of our favourite way of liberating energy.

That energy will probably come from burning fossil fuels

If the process was (possibly magically) efficient enough, you could run it on fossil fuels as long as you put away more than you create. You may also be fascinated to know that the back of your fridge is hot.

Seems feasible (5, Interesting)

gman003 (1693318) | about 2 years ago | (#41125977)

This actually seems like a feasible plan.

It plans not just for the extraction of atmospheric CO2, but the long-term storage of it. The power source is wind, so it doesn't fall into the trap of generating more CO2 than it generates.The choice of location makes sense for both the temperature and for the political neutrality. They don't list an actual cost, but it would likely be only in the tens of billions, hundreds of billions in the worst case. Which is a lot of money, yes, but not the trillions or quadrillions some plans have required. And it calls for a demonstration plant first, which would be just a few dozen million.

The only thing I see stopping it is politics. In particular, America and China. Europe seems to at least recognize the need for action, and they're willing to work together to try things. China is generally too selfish and shortsighted to worry about the environment, but you could probably convince them if you could make it somewhat-profitable for them (just have the wind turbines and such made in China, that should satisfy them).

But then it falls on to America. And you're going to need America at least not fighting this plan, because if the US decides to actively fight it, it's not happening. Period. You'd also need them to at least chip in a good chunk of the funding if you're going to do the full plan, make a serious dent in CO2. Problem is, denying the very existence global warming is a political *requirement* for half the country. They'll fight it just on principle, and I can't see the rest of the country fighting back for a project that doesn't have any immediate gains for the US specifically. While some sort of "compromise" could probably pull it off, or with luck it could be swept under the rug and never become a political issue, that's not guaranteed.

Still, it's the best plan I've seen so far.

The worst this could be called is a pork barrel project by those that are skeptical of the AGW claims. I would be one of those that is skeptical, given the amount of money to be made on both sides, and the politics involved with that. That being said, if CO2 is causing AGW, this sounds like a sensible plan. If it isn't causing AGW, then certainly sequestering as much as has been released in the last 200 years isn't going to do any harm. If it turns out that CO2 is causing AGW and we sequester too much and overshoot into too cold of temperatures, then the effects could be reversed by simply melting the solid CO2.

This actually seems like a feasible plan.

If it is feasible (and he has a rather odd title for a feasible plan), I wonder how it compares to fertilizing parts of the ocean with iron to encourage carbon sequestration through plankton growth. (Short explanation - in parts of the ocean, plankton growth is limited due to low iron levels, this plan adds iron to the ocean, the plankton take up CO2, die, then some of that CO2 ends up in the ocean abyss, where it tends not to escape (hopefully).)

Re:Seems feasible (1)

gman003 (1693318) | about 2 years ago | (#41126505)

The problem with that plan is that it's not completely under our control. It could bloom out of control, causing even worse climate change in the opposite direction, and we'd have no way to stop it. And it would cause damage to the regular oceanic ecosystem even if it did work perfectly - plankton blooms already cause mass killings of fish.

And I've also heard that it may not actually sequester the CO2 all that well (much of it returning to the atmosphere), but I can't be assed to check up on that.

Re:Seems feasible (2)

Let me ask you a question.

China could probably be convinced to do this on their own. A carbon credit right now is about $10 if I remember correctly. It's equal to 1 ton of carbon dioxide. If this plant cluster sequesters 1 billion tons per year, then that's China banking 10 billion per year. That would surely be a very short payback time for China, and if the program were expanded significantly enough, then China could eventually keep reinvesting the money from carbon credits into the wind farms, to eventually balance out the entire carbon output of humanity.

Re:Seems feasible (1, Interesting)

fermion (181285) | about 2 years ago | (#41127117)

So I am assuming that this proposal is meant to be tongue in cheek. While completely workable, it kind of throws the baby out with bath water, so to speak

To break it down, the climate change has to do with the production of energy, either to run our machinery or run our bodies. It is basically a result of a system that has not scaled well to out current level of consumption. For an end user solution we might help fix this problem by using less energy. This can be done by eating lower on the food chain, using more efficient appliance, such as LED for light, or releasing fewer pollutants form power generation facilites. This paper does not of these, so is not really a solution.

For a productions solution, we can change the kind of inputs we use to deliver energy to the end user. Cattle can be a source of pollutants, so maybe fish and vegetables instead. Coal can be very polluting, so maybe natural gas or nuclear or solar or wind. This paper suggests using a less polluting input, but this energy is not delivered to the end user, so is not a solution either.

So the tongue in cheek part is that we have an idea that can and will remediate the problem without solving any of the problems. It might lead to a solution, in that if we build lots of windmills for this, presumable we will have mass produced windmills we can use elsewhere. It might give us time to solve the problem, in that the "greenhouse gasses" will accumulate more slowly. One thing I must disagree with is that this plan would be favored by those who agree with human caused climate change. Quite the opposite is true. This plan is for those who climate change is a natural process. If climate change were man made, then the sensible solution would be for us to change our habits to stop it. If it is not man made, then something like this, technology to fix the problem at the atmospheric end, is the only justifiable solution.

That said I am not sure that machines like this are inevitable. There was a time when humans could just hunt and gather. At worst they could do limited agriculture. Now look at the amount of machinery the complexity of the supply chain just to get an ear of corn out of the ground. And look at flowers. We can't just keep bees around to pollinate them, they have to brought in special. And if cross pollination between orchards occur, and entire crop can be ruined. Is it inconceivable that as our population grows, as we cut down wild forest for crops of ranch land or managed timber, that the ability of the troposphere to support human life will begin to degrade. I can see atmospheric machine to insure oxygen content, CO2 content, even heat and humidity to be developed and deployed in the next few generations. Is this bad? I don't know, but it is something to think about.

Yes, but -- like anything else useful (water, oxygen), too much of it (also too fast an increase) can kill you (or, in this case, cause catastrophic climate effects).
CO2 isn't the worst of the greenhouse gasses, we're just generating lots and lots and lots of it all of a sudden, and the ecosystem doesn't have the ability to effectively deal with it that fast.

For an example of the effect, try drinking 20 litres of pure water tomorrow (just make sure to do it at a medical facility where they have some hope of reviving you when you collapse).

The dumbfucks who wrote the article copypasted the 10^12kg without copying the font. In the original abstract, the 12 was a superscript, indicating exponentiation.

I don't know... Formatted copy and paste fail? Yeah, I'm going to put part of the blame the shit state of software in general -- That's something that could have been fixed a long time ago.

At the same time sequestering 1 gigaton of CO2 a year as in the proposal is a drop in the bucket compared to the approximately 30 gigatons currently emitted by humans yearly. It's not that helpful unless we reduce emissions below 1 Gt and even then the reduction will be slow compared to the rate we've increased CO2. And you are right, those deposits of dry ice will have to be maintained essentially forever to keep the benefit. The plan just doesn't seem that practical to me.

Petroleum-funded proposal (-1)

Release Comrade X or we'll firebomb Antartica. You don't want all that carbon up in the air, do you? On the other hand, maybe it'll be cheaper just to burn more fossil fuels or start a fair-sized forest fire.

Please explain how your imaginary terrorists could firebomb Antarctica but couldn't do the same in a city. In theory, yeah they could detonate nukes in every city at the same time, but in practice that's very unlikely.

Interesting but... (1)

darkonc (47285) | about 2 years ago | (#41126189)

An interesting idea in the short run, but...

Building and maintaining a large infrastructure (especially something particularly mechanical like a wind far) in the especially hostile environment of Antarctica is going to have some really interesting engineering problems associated.
Then there's the problem of making sure that the CO2 remains frozen -- especially once the infrastructure is abandoned/broken
finally, there's the time bomb effect -- The antarctic ice belt Isn't static. It moves (albeit slowly) towards the sea, which means you're actually creating a CO2 TIme Bomb for some future generation to deal with.

Perhaps a better solution would be to put the power generation stations on Antarctica and find a way to distribute that energy to the rest of the world (or at least South America, Africa and Australia)

Re:Interesting but... (1)

ocratato (2501012) | about 2 years ago | (#41126455)

Agree completely.

Once we have a means of sequestering CO2, then there is no longer much incentive to stop creating it. We will just build a lot more coal fired power stations, and probably a lot more of these plants to cope with the ever increasing demand.

Eventually all this CO2 goes back into the atmosphere, and probably very quickly.

Another option (0, Troll)

Grayhand (2610049) | about 2 years ago | (#41126259)

I had wondered about artificially creating methane hydrate crystals either for storage in deep water or to be used as a cleaner fuel source. They should burn as clean as natural gas. I'm not a hundred percent sure of the process but I believe cold and pressure would cause the crystals to form so it'd involve mostly pumping CO2 into the deep ocean. You'd probably want to keep it semi closed to avoid raising acidity of the ocean water. I never liked the idea of underground storage since some of the biggest disasters in known history have been caused by major releases of CO2. Hydrate crystals are really stable so long as the temperature is stable. Raising deep water temperatures one degree would involve such a massive increase in global temperatures we'd all be dead anyway.

Poplar Farms In Northern Canada (1)

Anonymous Coward | about 2 years ago | (#41126389)

I like the plan of fast-growing trees like poplar being planted in Northern mainland Canada, then being cut and sent north to the Arctic ocean, and towed to places like Ellesmere Island for storage. Those high Arctic islands are so dry and cold, we simulate Mars missions there. The logs will sit there for centuries, holding carbon.

Modest Proposal (3, Insightful)

MyLongNickName (822545) | about 2 years ago | (#41126405)

I am amazed at how many people can't figure out that the dude is joking.

If you are saying that you need to create a power source to convert the CO2 from the atmosphere into a form that can be buried, then the logical choice is why you can't simply use this power source to eliminate CO2 producing power sources in the first place.

His 'modest proposal' should have tipped you off. Apparently, it was far too subtle for Slashdot.

Re:Modest Proposal (3, Informative)

Re:Modest Proposal (0)

MyLongNickName (822545) | about 2 years ago | (#41126529)

Hmmmm... you are correct. My argument stands though. It would be much more efficient to use the non-CO2 power source to replace CO2 instead of using it to bury CO2.

Because this power source is in Antartica (4, Insightful)

robbak (775424) | about 2 years ago | (#41126611)

A big point of this proposal is the strong, constant katabatic wind currents around Antarctica, which make the generation of large amounts of power feasible. But that power is in Antarctica, not New York, so you can't do much with it.

And, yes, you can extract much more CO2 from the air with a unit of power than is produced generating that power, even from Coal.

WE might want to fund a project called: HOTH Cli GigA DRIL (Halt Overt Terran Heating of Climate via Gigntic Arctic Death Ray and Intercontinental Laser), but one has to be a bit more subtle when presenting plans to the general public.

An Interesting Proposal (-1)

Ferretman (224859) | about 2 years ago | (#41126477)

Leaving aside the utterly disproven notion of AGW, this proposal has some merit and I'd like to see it proceed.

Several purposes would be served with a project like this:

- The infrastructure necessary to build and sustain these bases would be useful path-finding for outer space exploration;
- The technological innovations this type of project would generate could prove impressively useful for other, more concrete purposes;
- The Warmites would at least feel like they're doing something rather than just whining, so perhaps they'd actually leave people alone to go about their lives in peace

The plan is a good one if only for the first two points. I propose it become the UN's sole responsibility, with funding coming from dues already being paid by member nations and a direct tithe from various green energy organizations.

What a dumb idea (-1)

Anonymous Coward | about 2 years ago | (#41126537)

The question is not whether CO2 causes the climate to warm. The question is how much.

The application of basic physics says the climate will warm about a degree for every doubling of CO2 in the atmosphere. The alarmists postulate some kind of positive feedback that causes the planet to warm much more. The evidence to support that hypothesis is quite weak.

The skeptics like to point out that CO2 is plant food. It enables the world to produce more nutrition for the huddled billions. In that regard, CO2 sequestration is a dumb idea.

We should soon know who is right. There is a famous bet between an alarmist and a Russian scientist. The bet is whether the climate will cool between now and 2017. []

Those who think solar activity controls the climate point out that we are in for a serious slump in sunspots similar to what we had in previous cool periods. In any event, we should see who is right within the next decade. Our problem could be global cooling. That, if we take a lesson from history, is a much more serious problem than warming. We may look back at the idea of sequestration as idiotic.

Profit? (3, Insightful)

guttentag (313541) | about 2 years ago | (#41126545)

1. Build plant in really cold place
2. Profit from cold weather
3. Pull CO2 from atmosphere
4. Bury CO2 snow
5. Mankind benefits

You must be new here, because you've got this all out of order. Here's how it's supposed to go:
1. Build plant
2. Pull CO2 from atmosphere
3. Bury CO2 snow
4. ???
5. Profit!
If profit is not the end goal, then fail. If "mankind benefits" is the last item on the list, then fail. Go back and try it again. You don't have to be evil to get this right, but it helps.

Carbon can be sequestered on any good farmland (3, Insightful)

rycamor (194164) | about 2 years ago | (#41126663)

With the appropriate farming techniques, which have pretty much been forgotten in the age of high-volume industrial farming, carbon sequestration can be greatly increased [] .

It frustrates me beyond measure how our society tends to want to solve things with big, sweeping high-cost measures, and then when that becomes a problem, add yet another layer of over-engineering on top of that. Modern farming is one of the biggest problems in the carbon debacle. Cows are kept on bare concrete and fed a steady stream of grain, and the waste is just sloughed off to be turned to muck and eventually dried. Meanwhile, farms that grow produce tend to focus on only one crop (corn, wheat, whatever), thus progressively depleting the soil of resources for that crop, necessitating the high-volume production of fertilizer. Simple measures [] that can both increase the yield of farmland and create much healthier food, also happen to increase and thrive on carbon sequestration. If this were done on a major scale, I suspect our carbon problems would start to reverse.

But I know... promoting wholistic measures like this make one seem like an old hippy. Honestly, it's too bad. There are so many ways to save effort and improve things, but instead we focus on the dramatic high-effort, high-risk solutions.

An even more "modest" proposal: (2)

John Hasler (414242) | about 2 years ago | (#41126717)

Use orbiting shades to shade much of Antarctica so that it is dark most of the summer. This should make it cold enough to form CO2 snow, removing CO2 from the atmosphere. It also would increase H2O snow accumulation, but that's ok as it would bury the CO2 and also tend to counteract sea level rise.
