The purpose of this memo is to highlight the findings of an extensive literature survey and interviews with experts on the behavior of polymers in super-critical CO2 energy conversion systems that demonstrate foremost that there are critical knowledge gaps in this area that need to be addressed to improve design, reliability and lifetimes of system components. There are two brief discussions presented here: 1. SCO2 effects in polymers and associated mechanisms of failure, and 2. Summary of knowledge gaps identified in polymer/SCO2 interactions and science-based R&D to address the same.
