Giant fans used to suck CO2 out of the air

Carbon Engineering's machine used to remove CO2 from the airAs we consume oil (by driving cars) and coal (by generating electricity) that we extracted from the ground, it releases large amounts of carbon dioxide into the atmosphere which causes our planet to heat up. Kids around the world say the same thing – “Let’s just remove all the carbon dioxide from the air and put it back into the ground where it came from.” Meanwhile, scientists pooh-poohed the “silly idea” saying, “They’re just kids! What do they know!” Well today kids can triumphantly raise their fists in the air and shout “We told you so!” A company out of British Columbia has created a machine that can suck carbon dioxide out of the atmosphere and put it back into the ground!

The company is Carbon Engineering and the process they developed is called Direct Air Capture, a form of “negative emissions” technology meaning, we eliminate more CO2 that we make. Direct Air Capture uses a giant machine, about the size of a small building, with huge fans that suck in air from the outside and run it through a chemical process that removes carbon dioxide (CO2). The carbon dioxide gas is then compressed and stored in containers so it can be injected back into the ground – where it came from in the first place!

Nobody is sure if negative emissions technologies will really work. It still needs to be tested. And even if it does work, it is not the cure for global warming. To truly reverse climate change, we have to change how we use energy, be more responsible, and use science and technology to keep our planet clean and safe.
