#carboncaptureandstorage

All other (often thorny) issues aside, the idea of exploiting serendiptous poised chemical energy to capture CO2 is elegant.

Is there enough poised CE in the right places? Different matter.

"The success of industrial scale carbon capture and storage in geologic reservoirs depends on the permanence of the stored carbon dioxide (CO2). Carbon dioxide capture and mineralisation (CCM) or mineral carbonation, which is the conversion of CO2 to carbonate minerals via fluid-rock reactions provides low risk and permanent CO2 removal. Here, we demonstrate rapid mineralisation of industrial CO2 emissions in mantle peridotites. Captured CO2 from an ammonia plant in the Sultanate of Oman has been injected into peridotite at a pilot test site in the Samail ophiolite. Chemical and isotopic results indicate rapid carbonate mineral precipitation. Mass balance calculations suggest that ~88% of the injected CO2 was mineralised as carbonate minerals within 45 days after injection. This successful approach of CCM unlocks peridotite as a promising new type of reservoir for the safe and permanent disposal of anthropogenic CO2 emissions.

NatureRapid mineralisation of carbon dioxide in peridotites - Communications Earth & EnvironmentInjection of CO2-bearing fluids into peridotites of the Samail Ophiolite, Oman resulted in about 88% mineralisation as carbonate minerals within a 45 day pilot study, which suggests CO2 sequestration in peridotites may be at least as fast as in basalts.

"Breaching the target would ramp up the extreme weather already devastating communities around the world. It would also require carbon dioxide to be sucked from the atmosphere in future to restore the stable climate in which the whole of civilisation developed over the past 10,000 years."

This is bogus. Carbon-neutral #CarbonCaptureAndStorage is the modern perpetual motion machine: it won't happen. We can't put this genie back in the bottle.

3/9 The group does a lot of research in #conservationagricultre and #carbonfarming. You know, not the murky shady #CarbonCaptureAndStorage thing, but for soil improvement. They have developed a system that they call "CarBoniato". They use prunings of the city (Barcelona), woodchips, and apply them on a large scale on fields and when I say in large quantities, I mean 15 kg m-1 or 150 t ha-1!
The soil-scientist in you might say: this is madness. The C/N ratio will skyrocket. No plant available N for the near future anymore!

Despite the fanfare around CCS, it is a costly and risky endeavor and nearly all the world’s past CCS projects have experienced unexpected problems or failed outright. The technology’s poor track record hasn’t stopped the fossil fuel industry from championing new projects, and over the last few years, companies and governments have put forward a rash of new proposals that aim to store industrial emissions offshore under the seabed.
