GE has a wild plan to ‘vacuum’ air pollution right out of our skies — here’s how the mind-blowing idea would work
Story by Nick Paschal • 4h ago
It’s been decades since General Electric (GE) made vacuums, but now, it’s getting back in the game — only this time, the company will be vacuuming carbon pollution out of the air.
GE announced the successful test of its direct air capture (DAC) prototype and is planning larger-scale demonstrations in 2024. If the company can successfully scale its DAC system, it could be a massive weapon in the fight against our overheating planet.
What is direct air capture?
Direct air capture uses chemical reactions to remove carbon dioxide from the air. When air moves over the chemicals, it selectively traps the carbon, leaving the other parts of the air to pass through.
Once the carbon is successfully sucked out of the air and removed from the chemicals — typically by applying heat — it can be injected deep into the ground in geologic formations, never to be seen again, or used in products like concrete or plastic that will hold on tight to that carbon for a very long time.
