+OverSword Posted June 10, 2016 #1 Share Posted June 10, 2016 Quote Carbon dioxide has been pumped underground and turned rapidly into stone, demonstrating a radical new way to tackle climate change. The unique project promises a cheaper and more secure way of burying CO2 from fossil fuel burning underground, where it cannot warm the planet. Such carbon capture and storage (CCS) is thought to be essential to halting global warming, but existing projects store the CO2 as a gas and concerns about costs and potential leakage have halted some plans. The new research pumped CO2 into the volcanic rock under Iceland and sped up a natural process where the basalts react with the gas to form carbonate minerals, which make up limestone. The researchers were amazed by how fast all the gas turned into a solid – just two years, compared to the hundreds or thousands of years that had been predicted. source 3 Link to comment Share on other sites More sharing options...
bubblykiss Posted June 10, 2016 #2 Share Posted June 10, 2016 I saw this, pretty amazing, I just wonder what sort of effects it will have, you know, adding lots of new rock where there was none before. Link to comment Share on other sites More sharing options...
Doug1029 Posted June 10, 2016 #3 Share Posted June 10, 2016 I have to wonder how much capacity there is here. And who will pay for the system - probably not the polluters. Doug 1 Link to comment Share on other sites More sharing options...

Wow that was a bit quicker than they thought then -- Perhaps there's 'something' a bit special about CO2 that makes it quite easy to convert from a gas into a different state..? And that makes the name of the professor or whatever he is, quoted in the article, amusing -- “We need to deal with rising carbon emissions and this is the ultimate permanent storage – turn them back to stone,” said Juerg Matter, at the University of Southampton in the UK, who led the research published on Thursday in the journal Science. don't want to go too far away from the exact subject of the topic but here's another example of converting CO2 into 'something' else and this doesn't take hundreds or thousands of years either -- Published on Oct 8, 2014 For the price of less than 10 litters of fuel, you can cleanup the CO2 mess you have released in the atmosphere in the past.

back to earth Posted June 10, 2016 #5 Share Posted June 10, 2016 So all we have to do is connect every CO2 producing outlet to an underground pipeline that goes somewhere ...... just like under Iceland. Good luck with that one. 1 Link to comment Share on other sites More sharing options...
questionmark Posted June 10, 2016 #6 Share Posted June 10, 2016 I wonder much more how much CO2 it will generate to put 1 pound of CO2 underground. 2 Link to comment Share on other sites More sharing options...

Gingitsune Posted June 11, 2016 #9 Share Posted June 11, 2016 If graphen ever manage to become the revolution it hint it could be, we will need a lot of carbon for its production. In the meanwhile, the best way to store carbon is still to plant trees...https://en.wikipedia.org/wiki/Graphene Link to comment Share on other sites More sharing options...

Also, forests have a finite capacity to store carbon. Once that is reached, they stop sequestering it. Doug Link to comment Share on other sites More sharing options...

I wondered who would be the one to step forward and say something like this --- Yes anyone interested should definitely do research into the Keshe Foundation - and at the same time bear in mind that anyone proposing and sharing a new technology with applications to health, agriculture, energy, travel etc that threatens the big established industries, is always going to meet opposition - no one has to buy anything from the Keshe Foundation if they don't want to --- they can make it all themselves and 'ordinary' people all over the world are doing just that with home experiments - It's a huge subject and a huge project that is happening -- anyway the reason I brought it up was because of the CO2 thing - . 2 Link to comment Share on other sites More sharing options...
paperdyer Posted June 15, 2016 #12 Share Posted June 15, 2016 Someone correct me if I'm wrong, but limestone is CaO, correct? So where is the calcium coming from? The volcanic rock? if so what happens to the carbon? Are we potentially making new oil deposits for the next civilization that comes after us? To actually clean-up the atmosphere, are we going to have to separate the CO2 from it first? Capturing the CO2 from smoke stacks and the like seems to be a herculean feat at best.

Guest Br Cornelius Posted June 15, 2016 #13 Share Posted June 15, 2016 (edited) Limestone is CaCO3. The volcanic activity burns off the CO2 leaving CaO which is quick lime. Quick lime readily absorbs CO2 to return to CaCO3. This is why Lime is less polluting than cement because it absorbs CO2 taking it from the atmosphere when you use it as a morter. Combined with Hemp to make Hempcrete and it is a reducer of overall carbon emissions even allow for carbon neutral building. But I am inclined to agree that Carbon capture was a pipe dream which everyone with a rudimentary grasp of maths knew could never work out (the reason why almost all experiments have been abandoned). It was never meant to work - it was designed to offer a life line to the coal industry and create the impression that clean coal was just around the corner. A delay of just a decade in phasing out coal (which is what has been achieved) is worth trillions of dollars to the coal industry.

Finity Posted July 10, 2016 #14 Share Posted July 10, 2016 The carbon can also be re-used once solidified. It can be ground down and used in air and water filters. Link to comment Share on other sites More sharing options...
