But given that these predictions were made 5 years ago, progress doesn’t seem to be going as quickly as they’d like (or as all of us need). This is one of the world’s most expensive carbon credits, and is much higher than EPA estimates of the social cost of carbon and Exxon’s “target” number of $100/ton.Ĭlimeworks hoped to get this number down to $100/ton by somewhere in the latter half of this decade, at which point they would like to be responsible for removing 1% of carbon from the atmosphere. To get to this concentration, we need to remove roughly half a trillion tons of carbon out of the atmosphere in total.Ĭlimeworks sells credits for the carbon they remove from the air at a price of 1,000 euros ($1,048) per ton, and companies like Microsoft, Audi, and Shopify have already purchased credits to offset their impact. But that’s just net zero – we would then need even more plants to bring CO2 down from the current 420ppm back to 350ppm, which is the number we need to hit to bring the climate back into stasis. The fear is that the promise of this technology will delay action in reducing carbon emissions today, as humanity may think that a technological answer will eventually come for the chaos we are currently causing to our world.Īt the scale of this plant, a million similarly sized plants would be needed just to get humanity carbon neutral. It is favored by large polluters like Exxon as a way to reverse the enormous damage they continue to cause, though currently it is “too expensive” to be scaled in any meaningful way.ĭue to this expense and difficulty of scaling, environmentalists question its usefulness. Climeworks’ new plant will use geothermal power to operate, sucking carbon from the air and mixing it with water, then injecting it into the ground where it reacts with basalt to form solid carbonate rock. This new plant will increase their capacity by an order of magnitude.ĭirect air carbon capture is the concept that carbon can be sucked out of the air through industrial and chemical processes. 0001% of the 36 billion tons of CO2 emitted per year by humanity.Ĭlimeworks currently operates their “Orca” plant which captures 4,000 tons per year and began operations last year. When construction finishes in 18-24 months, their facility, named “Mammoth,” will be able to remove 36,000 tons of CO2 from the air per year – which is. ![]() The world’s largest carbon direct air capture facility has started construction in Iceland, run by Swiss startup Climeworks AG.
