back to article Only bicarbonate of soda can save mankind!

A US firm has come up with a plan to turn the carbon dioxide emitted by coal-burning power plants into bicarbonate of soda. Joe David Jones, founder of Skyonic, says he can capture 90 per cent of the carbon coming out of a smokestack and turn it into a harmless baking ingredient thanks to his Skymine process. The "baking soda" …

Using it in industry...

...would just release the CO2 anyway. I don't know how the Bicarbonate cycle works, though, so maybe it would cut down on fossil fuel used to produce it.

Just don't get it wet...

Bicarb will keep every fridge on the planet smelling sweetly, and we'll have plenty left over for scones and other baked goods.

And it does scrub up a bath nicely.

Trouble is you can't even use it for baking

...because that just releases the CO2 it's sequestering. Which is a shame, because I desperately want to see a harassed power station manager shouting "Quick! We need MORE CUPCAKES!"

The point is

the CO2 needs to be sequestered, i.e. not used for anything, given baking sodas chemical reactivity with water its probably not a good sequestration medium.

An Orwellian moment

Notice how, in a fairly short time, CO2 has become a "pollutant"?

Time was, a "pollutant" was SO2, or NOx, or a VOC.

Now, it's something people exhale. Something that plants call "food".

Already, China has claimed that they should be given carbon credit for their population control program.

I suppose methane will be next, which means we can expect the US to declare war on Mexico -- to "save the planet".

Rebranded Sodium Hydroxide scrubber

So he starts with Carbon Dioxide C02, and produces Baking Soda, NaHCO3.

Without any additional Sodium, or Hydrogen added, just heat. Methinks he's reinvented the sodium hydroxide scrubber and just forgot to mention the sodium hydroxide part. These are used on power stations to remove toxic metals and sulfur dioxide from high sulfur coals.

It does reduce CO2 aswell, now if only there was a way to make Sodium Hydroxide without generating huge amounts of CO2 (either directly LeBlanc or indirectly electrolysis).

Looks like somebodies rebranding their scrubbers as a fix for climate change.

I wonder how many news papers won't notice the missing sodium or hydrogen....

American?

We call it baking soda over here too!

I'd question whether this is a serious idea. Baking Soda works because the CO2 is loosely bound and is easily released in baking. Any scheme based on it would have to arrange for long term storage of the sodium bicarbonate in controlled conditions.

Mars because it would work fine there!

Huh?

So... How is this helping? Did NaHCO3 become a valuable resource or nutrient? If only there was some kind of self-replicating solar powered machine that could separate the carbon and oxygen atoms from CO2.

Hmmm... interesting.

http://skyonic.com/whatWeDo.php

says that:

"Our feed chemical for the reaction to remove the carbon is sodium hydroxide, which is produced on site as a part of the SkyMine™ process. This reaction to produce sodium hydroxide also produces hydrogen and chlorine as byproducts. These can be sold to market at a profit, not only defraying the cost of CO2 removal, but even generating a profit for the SkyMine™ operators."

It produces Sodium Hydroxide, Hydrogen and Chlorine. Sounds suspiciously like a salt-based reaction... The chloralkali process, mayhaps?

Is the super new technologically advanced "SkyMine™ process" on-site electrolysis of sea-water (cheaper at a power-station -- no transmission losses) followed by "scrubbing"? Followed by the disposal of half a million tons of water-soluble waste?

When I read this bit of the article I thought this was a mistake:

"Some googling, and little more serious research later,"

I thought it was supposed to be "*a* little more", but it doesn't take much serious research to come up with this (apparently) poorly thought-out system.

More about Skyonic

From a news release:

"Called the SkyMine process, Skyonic has created a new method that captures carbon dioxide and other pollutants and converts them to commercial-grade chemicals that are less harmful, such as hydrogen and certain forms of chlorine."

Now, wait a minute...

It "converts" Carbon Dioxide to "hydrogen and certain forms of chlorine."? There's only one "form" of chlorine -- unless you're counting isotopes.

And, how does it "convert" them? Do they wheel up a fusion reactor to the plant exhaust?

I smell a SCAM!

Raising agent

Not sure how edible it would be if it contained heavy metals or other contaminants

Baking powder: add 2 parts Cream of tartar to1 part Bicarbonate of soda.

Besides Kim & Aggies many uses it could be added to toothpaste, or instead of, for extra cleaning power, or a tsp. in a glass of water as an antacid for those morning after the night before moments (much cheaper than those over the counter remedies).

Talking of over the counter. A shop I used to work in sold Bicarb (mostly to old grannies who knew how to bake and/or were aware of its magical cleaning properties). Anyway 2 dozen tubs would take most of the year or longer to sell out. Suddenly however, it started selling out in a matter of weeks sometimes days, until a member of the local "Young Team" informed us that they use it to make Speed (Amphetamine Sulphate). They mix it with a concentrated paste to bulk it out into the familiar white powder. Similar problem with Jif lemon juice (used for dissolving Heroin prior to injection). We were surprised at the sudden interest in cookery shown by the younger generation. Now we know why. Needless to say we stopped selling both Jif & Bicarb

I don't know about everyone else but Baking Powder/Soda contains extra raising agents.

I've always called it Sodium Hydrocarbonate, because it surly isn't Sodium Bicarbonate (i.e Bicarb).

how?

Where does he get the alkali from? Its easy to produce it from limestone or sod carbonate. You just heat it up (?) and it expels CO2 into the air.

It can then be used to catch CO2.

Other methods I know of are equally pointless (eg electrolysis)

Anybody know how he gets round this?

Would be cool if he actually had a source.

OK their site says the heat is from waste emissions (fair enuff) and their feed source does not produce CO2. Still unsure how they get the NaOH. Electrolysis from electricity from waste (?)energy or wot? Probably as "This reaction to produce sodium hydroxide also produces hydrogen and chlorine as byproducts"

Still sounds like perpetual motion, but just possible.

Stop

Stop being so paranoid, Steve

"Time was, a "pollutant" was SO2, or NOx, or a VOC."

Nope, not so. You're simply being over-specific about the definition of pollutant. The dictionary calls it a waste material, something that renders a natural resource harmful or unusable: that seems a pretty reasonable term to describe CO2 to me. It describes "pollute" as to make impure with waste matter; again, a perfectly reasonable term to describe the excess CO2 emitted as a useless byproduct of industrial processes. Take a look at dictionary.com if you don't believe me.

"Now, it's something people exhale."

Umm, yes, that's exactly what a pollutant is: a useless byproduct.

"Something that plants call "food"."

That doesn't make it not a pollutant. Hell, some beetles eat shit. I'd still call it a pollutant if I found it in my sandwich; you can't just ignore the context like that.

Of course, you never actually say what you're getting at in your post.

Funny, that.

You suggest that someone has changed the meaning of the word - which as I show above has not happened at all - therefore implying that they have some ulterior motive; presumably the "Orwellian" reference is an attempt to suggest that it's some kind of propaganda or mind control exercise. But you stop short of coming right out and saying what you think it would be for, or about. My guess would be that you think CO2 is somehow not a pollutant, and that you believe that not because you've looked at the definition of the word pollutant and found it doesn't match, but because you have a hidden agenda which, in order for your point of view to be true, would have to mean that CO2 was not a pollutant, and you're reasoning backward from your assumption that you must be right about everything to what-would-have-to-be-the-case in order for you to be right about everything without any reference to facts, evidence, or even a dictionary.

Go on, tell us how you really feel.

@ Anonymous Coward

The pile of Bicarb would be twice the size of the "pile" of CO2 - so over 700,000 tonnes of the stuff.

As the 2006 world production was a mere 2.6million tonnes (http://www.google.com/url?sa=t&ct=res&cd=30&url=http%3A%2F%2Fwwwdev.ulb.ac.be%2Fdb%2Frevue%2Farticles%2F20092007%2F20092007REF_501.pdf&ei=rFdMR-XQO4GkwgGx562DDA&usg=AFQjCNFVvdyGME0_76kcAF7RbStkvIkmhw&sig2=G1F1MEGHmeGlqNrzJQ26YQ), I think an excess would be reached a little too easily... and the landfills would just release it far too quickly.

Nice(ish) idea, but clearly retarded.

Almost as retarded as the size of the url I just referenced...

Enzymes

This may not be the same technology, but there are some clever approaches to this that use enzymes. You first dissolve the CO2 in seawater, which isn't difficult. Anything with bones or a shell has an enzyme that can precipitate calcium carbonate from a suitable solution, like this. I think they also work for magnesium carbonate. Sodium carbonate [baking soda] might be a bit harder, but there are obviously plenty of sodium ions to play with.

I think that the bi-product is that the seawater ends up more acidic, which may not be a good thing - especially if it then dissolves the shells of marine organisms or the limestone seafloor, releasing CO2. But I'm sure they would have thought of that....

Hahahahahahaha....

Stick that up your ass Mr Gore! A way to carry on using power stations as we are without those nasty "Carbons" getting out.

Shame it's absolute bolocks -- think how muh energy would be required to transport the bicarb, not to mention lining the "old mines" with waterproofing.

Does highlught the major issue more though -- it's not the "carbons" that are the prblem, it's our reliance on fossil fuels for producing virtually everything, from foods to dyestuffs, that could be addressed. The climate will change by itself, reardless of the planetery disease "humans".

Baking soda with heavy metals? Yum!

Saves me time putting the cadmium in there myself... What a greatly convincing idea.

So indeed you save some effort in distilling the soda you need, but that's a pinch of that stack. You could maybe store it underground, where it will slowly react with water and release itself in the environment anyways.

A reasonable solution

Sorry, I just realized the titel might be considered a pun; not intentional.

Anyway... The State of Nevada is mostly desert (arguably, including Las Vegas, in a cultural sense). Burying the stuff in tunnels under the desert would lock up the CO2 for the foreseeable future, but make it accessible if it's ever needed (I can't imagine why it might be needed, but that's why you have "contingency plans" - for things you can't foresee).

And it would make large parts of Nevada, outside of Groom Lake, useful.

Some terrorist would pilot a plane full of vinegar into the mound, which would be pretty spectacular a scene if there were red dye mixed into the vinegar and the hill sized pile of sodium bicarbonate was thinly protected with a waterproof covering.

Twice as large as the pile of CO2, that's what.

" Assuming an average 500-megawatt power plant produces 338,000 tons of CO2 a year, we'd be left with a pile of bicarb roughly twice as large."

Wnat the article is saying is that an average 500-MW station outputs a certain amount of CO2 per year, and that if all that CO2 was combined with sodium and hydrogen and even more oxygen (in order to make bicarb) it would end up weighing twice as much as the original CO2 did before you added the extra ingredients to capture it.

Blimey, a straight answer to a straight question. I'll get me coat.

Re. Rebranded Scrubber

Our old friend AC has hit the nail on the head with regard to paying close attention to the 'total energy/pollution balance' considerations of the process; something that easily excited politicians hardly ever do.

The Skymine sites http://www.skyonic.com/whatWeDo.php and also the pdf at http://www.ostp.gov/PCAST/agenda_9_20_05_files/Jones_Skyonic_PCAST_20Sep05.pdf give a good top-level view of how they achieve it.

Essentially they use a small percentage of the power station output to electrolise sodium chloride hence producing sodium hydroxide (used as a scrubber) and also hydrogen and chlorine as 'valuable' byproducts. (That was my understanding, please read it yourself since I may have misunderstood).

How they manage to produce 'better than food grade baking soda' is a mystery to me given the toxic metals that need stripping out but is probably related to the ''Patent IP chemistry' they use. (How you can patent a chemical reaction is a separate issue of course, unless they use a specially developed catalyst?)

My main concern would be potential involvement of Durga The Hutt so this outfit needs to be watched carefully and all financial flows carefully accounted for. See http://starwars.wikia.com/wiki/Orko_SkyMine for an explanation of why.

And when the coal runs out?

Chemical attraction

"This reaction to produce sodium hydroxide also produces hydrogen and chlorine as byproducts"

So this is sounding a lot like hydrochloric acid - the dolphins would love that too. In fact, it seems as though they are producing chemicals that absolutely love to react with each other in a nice endothermic kind of way. I can't see this ending any way other than messily.

What's wrong with the old sinking the carbon dioxide to the bottom of the sea, or ejecting it into space on a carbon nanotube escalator?

Re: And when the coal runs out?

We actually have an enormous amount of coal globally. At the current rate of consumption we have 160-200 years left. Compare that to Oil and Natural gas which are closer to 30 years. Figuring out better ways to use coal to replace the other fossil fuels will be quite beneficial in the not-too-distant future.

Convert the sea water to sodium, chlorine, and water. Add the sodium to the water and get sodium hydroxide and hydrogen (and energy and the water has gone).

Ah, I understand now, "large" has become a description of weight, not size. Who says that standards of English aren't dropping? Of course, if you were to use the language properly, the pile of baking soda would be many times smaller than the "pile" of CO2, one being a solid and the other being a gas at more or less standard temperature and pressure after it comes out of a power station.

Good Ideas Bad Ideas

So the Bicarbonate is unstable when water is around, what we need to do is further process the bicard. This is not a solution in itself but as a method of catching the emissions at the point of production it sounds good.

@Desalination Plant, bad idea you don't say where all that chlorine ends up, we still have to think about the ozone layer.

CO2 is a pollutant. yes I know we all breathe it out but we all pass urine as well. If I piss in the loo then no harm done, if I piss in the local swimming pool then that pollution, same goes for CO2 it depends what you do with it.

This reminded me of the carbon recycling scheme used in the South of France:

The only reason the Med isn't more polluted than it already is, is that huge mussel beds grow around the sewage outlets, filtering all the crap out of the water. These mussels are then harvested and fed to the tourists, thus removing two problems at the same time.
