The article discusses the significance of material choices in blue hydrogen carbon capture technologies, particularly focusing on the impact of selecting the right elastomers and thermoplastics. A new whitepaper by Greene Tweed highlights the importance of material selection in industries relying on carbon capture, utilisation, and storage (CCUS) to enhance equipment longevity and reduce maintenance costs. Most CCUS systems use amine-based solvents for CO2 capture, which can lead to chemical degradation and mechanical failures in system components like seals. The whitepaper suggests that conventional materials like NBR, FKM, PTFE, and standard PEEK may not offer sufficient resistance to amine-induced damage. Instead, perfluoroelastomers (FFKMs) and cross-linked PEEK are recommended for their superior performance in harsh CCUS environments. The article emphasizes the critical role of precise material selection in ensuring optimal performance and reliability in demanding conditions. It also mentions the necessity for advancements in material science to meet evolving application requirements for reducing emissions. Overall, the sentiment of the article is positive, highlighting the advancements in material technology to address challenges in blue hydrogen production and CCUS applications.
