I was excited to see the article and the response to this post is really heartening. I will echo other comments by saying that your HN pitch is well-written.
I do have a question: in conventional capture processes, the step that makes the process cost-prohibitive is regenerating the absorbent or adsorbent because it is so energy-intensive. You say above that CO2 (and water vapour) is absorbed by an aqueous electrolyte. How do you separate the CO2 from the electrolyte solution?

The CO2 is absorbed in the electrolyte, and that's where we use it in the catalysis process. It is turned into fuel within the electrolyte, then we extract that fuel from it.
