Yes clathrates. Methane forms them too. There are large
deposits of methane clathrates on the ocean floor, metastable
at their present temperature of pressures. But if they warm
up just a little, they'll let lose.
It might have happened in the past, google methane
They're talking about pumping it into the voids under the
North Sea left over from petroleum extraction. At those
depths it will liquefy, or maybe form clathrates.
Sounds nuts to me.
I think there are some oil drilling and distribution rigs. Would not be
good if they get damaged. There was an earthquake of sorts (3.5 on the
Richter scale) in the province of Groningen (Netherlands) where there has
been so much subsidence and damage that the local government and the gas-
winning company (NAM by their Dutch initials) are paying compensation. I
don't know whether there are plans to "fill" those voids with anything,
but I believe that in some places water injection is used to crank up gas
and maybe oil winning. That's where CO2 or carbonate injection could
What about converting the CO2 to carbonate? I think this is how some
The product of which (Na2CO3, K2CO3, CaCO3) could be sold to off set the
cost of scrubbing.
The product carbonates also take up less volume to store.
And what would they do with it? Remember, you can't allow any uses
that result in it releasing CO2--if you do then you may as well not
have wasted your time making it in the first place. That means no
baking with sodium bicarbonate, no making cement out of calcium
SOOOO very WRONG!!!! Most carbonates are mined. Which is better for
the environment? Dumping tons of mined carbonate-co2 into the atmosphere
or recycling/reusing co2?
Below are a few from Wikipedia:
Sodium carbonate uses that do not release CO2 (From WIKIPEDIA)
In casting, it is referred to as "bonding agent" and is used to allow wet
alginate to adhere to gelled alginate.
When mixed with water and put in a spray bottle, it is sold for its
anti-mold cleaning ability. It is also used to blast off mold from wood or
In domestic use, it is used as a water softener during laundry.
FYI after your dry ice density response, I am beginning to think you are a
Can you replace the mined carbonates one for one with that produced
from your power plants?
Yes, those are "some uses". What is the _major_ use?
And if it's used as a "water softener during laundry", _then_ what
happens to it?
Same for "anti-mold cleaning"--what happens to it _after_ that? Does
it cease to exist after it goes down the drain?
I dug up a reference for ya. This guy is using NaOH as the base so he ends
up with NaHCO3 (baking soda). Is there a market for super pure baking
CO2+H2O <----> H2CO3
H2CO3 + NaOH -----> NaHCO3 + H2O
Not carbonate in this reference, but bicarbonate. I suppose if you adjust
the amount of NaOH and monitor the pH you could also make Na2CO3 with his
Now, find out what the major use of baking soda is. I believe that
you will find that it is, well, _baking_. Then look at what baking
soda does when baking. It reacts with acidic components of the recipe
to release CO2. So the CO2 is not locked away where it doesn't
contribute to greenhouse emissions, it's just released a little later.
Of course you could make baking soda and store it in a warehouse
somewhere forever and ever and ever and ever and ever and pray that
the warehouse doesn't burn down, because when you get the stuff hot,
what does it do? It breaks down and releases CO2.
