Considering the number of annual deaths caused by pollution, it not only makes sense to cut emissions but to also improve air quality. All over the world, groups are working to make the atmosphere as breathable as possible. Bogota is erecting vertical gardens while China is manufacturing air-purifying bicycles. Not to be outdone, Iceland has set up the world’s first negative emissions power plant.
Climate startup Climeworks refitted a geothermal plant in Iceland to remove carbon dioxide from the air while also generating power for thousands of homes. This carbon dioxide is safely embedded in rock, where it will remain for millions of years.
The storage process, called carbon capture and storage, is keeping temperatures from rising to extreme levels. The facility is projected to remove 50 tons of carbon dioxide from the atmosphere annually. It isn’t much — but it’s something! The procedure is also fairly straightforward.
Climeworks uses… [the] plant’s waste heat to run their own carbon capture tech, pulling carbon dioxide directly out of the air and feeding it into the existing Carbfix infrastructure, which deposits it in underground basalt. There, the carbon dioxide forms crystals within two years, and remains stable underground for millennia.
Limited to information from my high school physics class, I hardly knew trapping CO2 was possible. Either way, we should be over the moon to have chemical engineers.
