Negative emissions plant comes online in Iceland

Climeworks and Reykjavik Energy launched operations at the world’s first negative emissions plant, according to Engadget. The geothermal plant in Hellisheidi actually removes more CO2 than it produces. Using the Climeworks system to capture CO2 out of the air, at a rate of 50 metric tonnes a year, it then binds the CO2 with water before embedding it back into the earth where it remains for billions of years. While the system may not yet be cost effective, the price for the technology is dropping, and aside from the environmental benefit, it could appeal to major cities with smog issues.
