About the Sorbent category

The chemical material that does the work of absorbing CO2 is called sorbent. For our first Epiphyt build in Philadelphia we used a zeolite-based variety, because it was cheap and available. But it didn‘t perform well, and absorbed more H2O than CO2. So we are seeking alternatives. And in the longterm we see Epiphyte as a platform for testing and deploying novel sorbents.

If you are in the sorbent game and want to share ideas on how Epiphyte can select for optimal approaches, please post them here.

Here’s a video overview of the sorbent issues we are facing in Spring 2024.
