Is Sequestration The Answer?

We're just returning the carbon to where we found it and removed it from in the first place. How it that "sweeping it under the rug"? I'd say it is sending it back home!

kinda like energy,

I feel you have inhibited discussion by using the word 'Sequestration'.

Ok ..I looked it up.. but in this context it is ambiguous.

Do you mean forcibly removing power sources... surely not invading for oil?

Or maybe collecting CO₂ and forcibly stuffing it up the arse of the person who generated it?

Confuse a Cat.

Lets have short posts with short words please...my furry brain can't handle the big 'uns.

Se-the act of vision

Quest-a journey towards a goal

Ration-a controlled distribution of resources

hmm could be a nefarious plot to corner the market on carbon black, disabling printers across the planet!

Draw your own conclusions.

Hi Del.

Actually he has a point, and I too think the same way as PWSlack does! At the moment they are talking about pumping exess CO2 down into deep oil wells, this seems to me to be an altogether wrong aproach? By burning fossil fuels we have and still are producing vast amounts of CO and CO2. These gasses were combined with other elements to produce these fuels, in that form they were very stable over many millions of years. One does not need a super brain to understand that these gasses that are to be pumped underground will one day leak from there underground storage. One very small earthquake in these zones and the stored gasses will escape in vast amounts!!!

Another thing, what part of "Sequestration" don't you understand???

Spencer.

See this

1st useage suggests confiscation of property from thos who in some way don't coply with law. The 3rd use is presumably the one that was meant...

It seems a classic use of long words for the ske of it...why not simply say what is meant. If you mean stuffing CO2 underground or storing it in someway then say so.

Plain English please.

Del,

Sequestration is a perfectly good word, and is specific to how the CO2 is removed from the atmosphere.

It means that the CO2 is bound up chemically as a stable compound, rather than as a free gas. This can occur by any number of natural or man made process.

Pumping CO2 into the ground is not sequestration.

Formation of CaCO2 (limestone) is, as an example.

Tad

Isn't carbon sequestration really the question? We'd like the oxygen back please.

Yes it's a lovely word..it has more than one meaning however which could be applied to punitive reparations against those who polute with CO2...

I do understand which use was meant now...but feel simple English would have avoided wasted part of my life decoding unnecessarilly contorted ...sod it I can't be arsed to explain myself yet again...I thought I'd done it twice already...

Hi Tad.

Calcium carbonate (limestone) should read; CaCO3. Spencer.

Well, we'll let the CO2 in the atmosphere help the peat bogs grow. Then we will let them slowly sink under the ground through tectonic plate movements where they will be placed under great pressure and higher heat. Then we will dig it up and burn it in steam-electric plants to operate the telly. Repeat.

I have always had a problem with the concept of hiding away the CO₂. We may just need the oxygen that gets hidden away as well.

I have to agree. I have heard lots of talk about "putting the carbon back where it came from",only problem is, where it came from it didn't have the oxygen!

Now I may be naivie (sorry for the big word), but the earth is (more or less) a closed system. Stuff the CO2 underground and you are taking an awful lot of O2 out of circulation, and we may just need it one day.

I don't see how you can strip the oxygen out of the CO2 before stuffing it underground without supplying at least as much energy as you got from burning the carbon in the first place, so that won't work

The other consideration is what happens when you re-introduce massive amounts of carbon into a closed system.

Global warming anyone?

In short, is sequestration the answer? Not unless you can hold your breath for a REALLY long time!

Run it through a catalyzer and remove one oxygen molecule, then just bury the carbon monoxide.

Without wishing to sound macabre;

Thanks for raining on my parade.

(I'm doing contract work for a company that builds these things)

And I did have it backwards, Catalyzer will bond and oxygen molecule to that carbon monoxide changing it into C02 which is a more environment friendly.

(not for us humans)

Thanks for raining on my parade.

My beloved bath has just 'bit the dust'. I apologize if I seemed tetchy, but my tears are beyond telling.(search and ye shall find).

As it happens I am fairly well acquainted with people who are in the business of making big holes in the ground. Either to take stuff out or put it in - makes no difference to me, they want a big hole - I help design it. I could stick a rock bolt far enough up that you'd believe. Freeze your turf ? No problem. Take you so deep you'd fry ? Come on down. Not so much now, but I sure know some of the basic principles . Don't ask cos you can't afford my freelance rates - just let me say you are probably sitting near a **** load of storage facility I helped design.

What do you want to put in it and how deep - they are my only real questions. Like anything on the net you either believe or you don't, but if you ever want a big safe hole in the ground -ask me. CR4 is where I play and and have fun. Big holes in the ground is serious money - you best believe I take my %. Macho post out.

so your the guy that puts stuff where the sun don't shine.

Wouldn't it make more sense to convert the co2 to algae for the production of biofuels?
