Iceland switched on the biggest air-cleaning machine on Earth.In May 2024, a facility called Mammoth began operations in Iceland. Built by Swiss company Climeworks, it’s designed to remove up to 36,000 tons of carbon dioxide from the atmosphere each year – 10 times more than its predecessor, Orca.The process is called direct air capture (DAC). Giant fans pull in ambient air, and specialized filters trap CO₂ molecules. That CO₂ is then mixed with water and pumped deep underground into basalt rock formations, where it slowly turns into solid stone through a natural mineralization process.And it’s all powered by Iceland’s geothermal energy, meaning the entire system runs on clean, renewable power.The captured CO₂ is stored by Climeworks’ partner, Carbfix, which developed the underground injection method. Over time, the gas reacts with the rock and becomes part of the Earth – locked away for good.Science and facts💡
