isting validation techniques to determine the suitability of a compound . ISO 23936- 2 ( NORSOK M-710 ) serves as an excellent benchmark , allowing the substitution of standard gas mixtures with CO 2 for bespoke RGD testing . By adhering to the principles of this standard , it is possible to broaden the scope of testing to include variables beyond just the gas itself , such as test temperature and seal cross-section , to challenge materials rigorously . |

Certain elastomer products like James Walker ’ s Vermilion ® Four have been subjected to rigorous RGD testing in environments with high CO 2 levels and elevated temperatures , with outstanding results , leading to its selection for deployment in a significant North American CO 2 pipeline project . Similarly , Vermilion Two has been accepted by operators of a major European carbon capture project after undergoing evaluation in stringent conditions at a third-party laboratory . By testing at elevated temperatures , and successfully achieving a perfect result of 0000 when evaluated using the ISO 23936-2 acceptance criteria , the materials provide the confidence that they will work in safety critical applications .
Conclusion
As the world moves towards a low-carbon future , CCUS technologies will play an increasingly important role in reducing greenhouse gas emissions . However , the successful deployment of CCUS depends on overcoming a range of technical challenges , particularly in the handling and storage of CO 2
