>We have developed a process to bring air in contact with a base substrate that captures CO2 molecules while letting N2 and O2 molecules pass through. After energy is applied, CO2 is desorbed from the substrate for downstream treatment and compression.

This sounds very similar to how Verdox[0] is approaching the problem. What sets your approach apart?

That's basically the default approach that's been used for >100 years.

[Patent US1783901A](https://patents.google.com/patent/US1783901A/en ) (1930-ish) shows the basic closed-loop configuration that most folks build from.

Gist is to sorb acid-gas (like CO2) into a basic-solvent (e.g., aqueous monoethanolamine), then heat it up to release the acid-gas. Then the regenerated-solvent can be reused.

Making the process closed-loop may've been more of a focus around 1930. Before that, I think there were some patents showing open-loop designs (this is, designs where the solvent isn't regenerated-and-reused).

Thanks for the question, we'd rather not speak to anyone else's technology, except to say that we support anyone working to advance CO2 removal [copied from comment below, trying to keep up with all the questions/discussion!]
