Is Sucking Carbon Out of the Air the Solution

by bernt & torsten

In British Columbia, there is an industrial plant that aims to replicate what those millions of trees do: suck carbon dioxide out of the air. 

The plant was built by Carbon Engineering, using a technology known as direct air capture (DAC). In a long, squat building, a huge ceiling fan draws air inside, where it reacts with a liquid chemical that grabs hold of CO2 molecules.

This “sorbent” flows into a nearby machine that transforms the gas, which is then stored in pressurized tanks. The goal is to help rid the atmosphere of its most ubiquitous climate change culprit.

Shallow dive: The carbon cycle is a series of chemical reactions and tectonic activity, carbon takes between 100-200 million years to move between rocks, soil, ocean, and atmosphere in the slow carbon cycle. It makes more sense we stop cutting down trees, replanting a forest, restore our marshes, use gardens and our lawn to build food forests. Then capturing carbon from the air so we can just live our lives as in the status quo.
