<aside> 💡 Currently, my goal is to make carbon capture profitable. Read more about my thoughts on that below.

What I’m building

<aside> 💡 note that everything is subject to change

</aside>

I’m designing a process to capture atmospheric CO2 and convert it to battery-grade graphite.

The goal is that I can take this graphite and sell it to battery manufacturers, or create my own thermal batteries (this is a moonshot).

The process will have 2 components:

1. Capture method for atmospheric CO2
2. Electrolyzer to convert the solution into graphite

Eventually, I’d like to create another process to turn my graphite into a battery. This will come later.

How it works

Here I’ll go into which decisions I’ve made. The larger “why,” behind them can be explored in Carbon Capture Memos | ahnaafk.com which I am continually adding to.

Capture Method

The carbon capture status quo is direct air capture (DAC). A great example of this is Carbon Engineering’s (CE) DAC system detailed in this paper. I won’t explain their process fully here as I’ve done that already in Going Deeper on Carbonate Conversion | June 13, 2024.

Carbon Engineering’s simplified process diagram. Taken from the paper mentioned above.

There are some details that I want to make note of:

• CE’s process wastes minimal resources. Pretty much everything that they use is regenerated or recycled in some fashion.
• They mostly repurpose existing technology and fit it for their purposes.
