Construction Begins On 'Mammoth' Direct Air Capture Plant

Thursday June 30, 2022. 12:00 PM , from Slashdot
Swiss climate tech company Climeworks announced yesterday that it has broken ground on its biggest facility yet for capturing carbon dioxide from the air. The Verge reports: The new Direct Air Capture (DAC) plant, named Mammoth, will significantly scale up the company's operations in Hellisheioi, Iceland. That's where Climeworks built Orca, which was the largest DAC plant in the world when it came online last September. Orca can capture up to 4,000 tons of carbon dioxide a year, roughly equivalent to how much climate pollution 790 gas-guzzling passenger vehicles release annually. Mammoth, in comparison, can capture about nine times as much CO2 as Orca.

There are fewer than 20 such plants in the world, according to the International Energy Agency (IEA), and they don't yet have the capacity to make a serious dent in the greenhouse gas emissions humans have dumped into the atmosphere. The IEA says that to do that, the direct air capture industry has to grow to be able to draw down 85 million metric tons of CO2 by the end of the decade. For comparison, it captures just 0.01 million metric tons today. That'll likely require a new generation of DAC plants, each capable of taking in 1 million metric tons of CO2 per year. So in the grand scheme of things, Mammoth -- with the capacity to capture 36,000 tons of CO2 a year -- isn't quite so mammoth. Even so, Mammoth is an important test case for scaling up Direct Air Capture tech.
