Signal COF-999 captures CO2 faster and at lower temperature than incumbent sorbents

Summary

COF-999 is a covalent organic framework, a porous crystalline material, that has shown better performance than existing sorbents for capturing carbon dioxide. It takes up CO2 more quickly and works at lower temperatures than competing materials. It also holds up better under repeated use, losing performance more slowly over time. Because the sorbent drives much of the energy and replacement cost in capture systems, these properties could substantially lower the running cost of carbon capture, utilisation and storage. The signal suggests that progress in capture economics may come from the chemistry of the capture material itself rather than only from larger plants.
