In the case of DAC, good adsorbent performance should not be the only consideration for adsorbent selection. The manufacturability will determine the capability for large scale deployment. Those based on existing commercialised products (e.g., macroporous polymer resin supported amines, and cordierite/alumina monolith supported amines) are available and can be scaled-up. However, proposed adsorbents that have challenging manufacturing processes (e.g., nanofibrillated cellulose supported amine) have very low yields and may impose a supply chain bottleneck.
