Air Quality in Iceland

The Icelanders developed the first plant with negative emissions. Indeed, 20km from Reykjavik, the Hellisheidi geothermal power plant not only emits very little CO2, but also cleans the surrounding air of other emissions. The air is absorbed, filtered and cleaned before being released. As for the CO2, it is retained by filters and mixed with water, before being injected about 800m deep in the ground, where the mixture is transformed into stone. Although the technique still represents a small-scale solution, it is a step forward in the fight against air pollution.
