In Iceland, CO2 sucked from the air is turned to rock Jereme Richard 2021 Nov 02 phys.org techxplore.com/news/2021-11-iceland-co2-air.htmlIt appears that this organization in Iceland wants to establish a business of turning other people’s CO2 into rock. |

No longer a last resort: Pulling CO2 from the air Marlowe Hood 2022 Apr 01 Phys.org phys.org/news/2022-04-longer-resort-co2-air.htmlNo, not an April Fool’s but dead serious that we aren’t going to make the global temperature goals without removing carbon dioxide already in the air. |

Actually, the article might be a joke, at the expense of the gullible by those in the know. The arithmetic seems to be tongue in cheek, if not downright quackery. In the second paragraph, it says that if we had been reducing the rate of emissions by 2%/a (simple) across the 28 years to 2030 we would have arrived at "the right path". However, reducing our rate of emissions by 56% would leave us still emitting at 46% of today's emission rate. Anyone in the know is aware that any continuing rate of emissions dooms us to warm past any target temperature whatsoever. The article then goes on to say that the same could be achieved by 7%/a (simple) across the remaining eight years. Although that also implies a 56% reduction in the emission rate, its late application means that the greenhouse would have accumulated more emissions than in the earlier scenario. The article then goes on to imply that that action would help "capping global warming". However that reduction of emission rate would be the sum total of humanity's efforts, so the rate of emissions would not be extinguished. While any emissions continue it is impossible to cap global warming. The article then speaks of "the most aggressive carbon-cutting scenarios" without actually specifying what they are, and that they are not. Quite obviously the most aggressive carbon cutting scenario would be the immediate and total destruction of all coal mines and oil and gas wells. That would do the trick! The rate of emissions would slam to a halt. The accumulated emissions already in the atmosphere/hydrosphere would continue to maintain the current rate of climatic disasters, but at least they wouldn't worsen. Seeing as the accumulated emissions are already ~2000 Gt CO2, and would be several times that by 2100 under any emitting scenario, the article's bland assertion that a return to today's climate will only require us to remove a few hundred gigatons is cynical, or a cruel joke. Cynical not only in its gross underestimate, but cynical in its impossibility. None of the methods it quotes to vanish carbon dioxide are capable of hiding that much CO2 forever. I think the article is at best a jocular reassurance that we can allow ourselves to continue emitting as much as we darned well like, as long as we make some ostentatious (though futile) gestures, and popularly term them "reductions". |

Aluminum Formate Could Filter CO2 at Power Plants Claire Turville 2022 Nov 28 EEPOWER eepower.com/news/aluminum-formate-could-filter-co2-emissions-at-power-plants/Aluminum formate is a MoF, Metal-organic-Framework, forming a cage the right size for the CO2 molecule but too small for nitrogen molecules. Removed to an enclosed environment, gentle heating releases the CO2 so that the MoF can be reused. Alas, humidity destroys he MoF, so use in flue streams depends upon drying of the flue gas. Maybe someboedy can figure out how to accomplish that inexpensively. |

Storing carbon dioxide underground may be a safe solution to mitigate claimate change, according to new study 2023 Jan 31 Phy.org phys.org/news/2023-01-carbon-dioxide-underground-safe-solution.htmlComputer study of carbon dioxide injected deep underground in sandstone. Of course even better is to inject into porous mafic rock, such as basalt, where over time the carbon dioxide react with the rock. |
