James Walker has undertaken a detailed test program to characterise the effects of CO2 on polymers in line with API 6D, Annex M, ISO 23936‑2 (RGD), ‑ the findings are outlined in this article.
Carbon Capture, Utilisation and Storage (CCUS) continues to grow at a significant rate. Between 2025 and 2026 there was an almost 50% growth in the value of projects receiving Final Investment Decisions in the UK alone.
Technical challenges with sealing carbon dioxide have been well documented, but a combination of technical unknowns, tight cost controls, and rapid project roll out can mean there is limited time and scope to undertake extensive research to truly understand the engineering issues that could arise.
For this reason, James Walker has continued to invest in developing an understanding of CO2 sealing challenges, ensuring it is easy for engineers to understand risks and make informed decisions on material selection and sealing devices using validated data, without incurring additional costs or experiencing delays.
This report outlines the latest findings from James Walker's research regarding high pressure CO2, focusing on elastomers and thermoplastic seals and materials.
