Proposals to store CO2 underground

We are told that the world is warming and humanity is the cause.
We are told that our burning of fossil fuels releasing CO2 is the main problem.
I am not entirely convinced
but surely this new proposal to inject super cooled CO2
800 metres underground is coming at the problem (if there is one)
from the wrong end and damn risky.
Already too much CO2 in caves.

"A storage site 800m or more underground will ensure that the pressure will be great enough to keep the CO2 in its liquid state."
 
Sounds like a good idea to me, and i think i'll just trust that the engineers get it right. I find life's much better when taking that sort of attitude.
 
Who should I trust - the whingeing windbags who take a negative view on anything they don't understand (or think they do understand but don't really), or the engineers who have been properly educated to investigate things properly and come up with viable answers. A difficult one that.

A link to a news item about a pilot scheme in Germany to extract the CO2 from the exhaust gasses. Seems to me the biggest problem is that having done this the cost is then comparable to the renewable energy sources like windpower. As ever, funding and agreement will probably be more significant than practicality or usefulness
 
Methane, a highly volatile substance, has remained underground for many millions of years in one of the very same places that it is proposed pumping carbon dioxide. Whether gas or liquid, if carbon dioxide stays in the same place for a fraction of that time then I have no concerns. Sounds like a good plan to me. Go do some simple research before making obviously naive false scientific statements.
 
WL, these so called scientists have obviously missed some easy points that you've spotted.
you'd better ring them up and explain why their evil plan will fail.
 
Just maybe.... they haven't thought about it that much yet other than as a hypothesis. BUt nice headlines in the BBC should help with getting grant aided funding for a few years of employment whatever the outcome of the research!!  ;) ;)
 
A good deal of practical work towards a functioning system seems to have taken place already. I just do not believe that money would have been spent without a good degree of certainty that the ultimate procedure would work. The technology to handle liquid carbon dioxide in quantity has been around for decades and this is one step further along the chain of technological development.

Why always go for the technological approach.
This carbon sequetration seems very involved and expensive, I agree that it is jobs for the boys.
Were nuclear bombs such a good idea?
Nuclear power is a nonesense
what's wrong with renewables 
:thumbsup:

Do you not think, Kay, that is a very good indicator that, as a species, we should be looking at reducing our relentless demands on finite resources, and perhaps consider living within our means?

Not entirely convinced by that argument, Mick. I wonder, will you think it's a nonsense when your power supply is rationed?

Kay we could always have another crack @ The Three Day Week
I have fond memories of that
:)
http://en.wikipedia.org/wiki/Three-day_week

The Three-Day Week was one of several measures introduced in the United Kingdom by the Conservative Government 1970-1974 to conserve electricity, the production of which was severely limited due to industrial action by coal miners. The effect was that from 1 January until 7 March 1974 commercial users of electricity would be limited to three specified consecutive days' consumption each week and prohibited from working longer hours on those days.
 
It'll make no difference to us, we will still have to work every day!!

I am all for attempting something new. After all, what is the worst that can happen? It will all turn back into gas and escape back into the atmosphere poisoning a few cavers on its way up!

No, the worst that can happen if we generate 2 tons of C02 for every ton we put underground, and it STILL leaks out again.

It takes energy to capture the CO2, energy to freeze CO2, more energy to force it down a hole. Getting that energy releases CO2.... er..... wonder what the maths is on this. :-\
