Carbon removal factory

In September, Climeworks flipped the switch on Orca, the largest plant to date that is designed to remove carbon dioxide from the air. 

The facility, outside Reykjavik, Iceland, can capture 4,000 metric tons of carbon dioxide every year. Large fans suck air through a filter, where materials bind with CO2 molecules. The company’s partner, Carbfix, then mixes the carbon dioxide with water and pumps it underground, where it reacts with basalt rock and eventually turns into stone. The facility runs entirely on carbon-free electricity, mainly from a nearby geothermal power plant.
