Can Artificial Shells Reduce Carbon Dioxide?

The Canadian company Carbon Engineering takes carbon dioxide out of the air and turns it to calcium carbonate – that’s what shells are made of! They developed a scalable process for capturing carbon dioxide from the air, a technology called Direct Air Capture (DAC).

Imagine an industrial plant with big fans to suck in air. This air is then mixed with chemicals and turned into calcium carbonate pellets.

What stage are they at? That’s the interesting part. Carbon Engineering have been capturing air from a pilot plant since 2015. Now in their commercial validation phase, they received major backing from industry to scale this technology.

Our proven Direct Air Capture (DAC) technology can scale up to capture one million tons of CO₂ per year with each commercial facility. That quantity of CO₂ is equivalent to the annual emissions of 250,000 average cars.

What I like most about Carbon Engineering is that they have been capturing carbon dioxide from the atmosphere for several years now and are ready to scale. We need to use all the options we have reduce emissions and to remove carbon dioxide out of the atmosphere, and this definitely sounds like a good one.

While I personally like shells, they are turning it into something of more monetary value: Fuel. Stay tuned for part two of this post to read all about how Carbon Engineering creates clean fuels.
