Corrosion in CCS: Lessons Learned and the Road Ahead

Presentation: Corrosion in CCS: Lessons Learned and the Road Ahead

Carbon Capture and Storage (CCS) plays a vital role in the global effort to reduce CO₂ emissions. While pure, dry CO₂ is generally non-corrosive, real-world CO₂ streams often contain impurities that can significantly accelerate corrosion and jeopardize the integrity of transport and storage infrastructure. This seminar will explore current knowledge surrounding corrosion and material degradation in CCS systems. Despite growing research in this area, several critical gaps remain—particularly inconsistencies in reported findings, limitations in experimental setups, and uncertainties about long-term performance—which undermine the reliability of predictions and system design. To address these challenges, this seminar will present a research initiative focused on investigating the in-situ chemical interactions of impurities in CO₂ streams and their impact across the CCS value chain.

Presenter: Professor Thunyaluk (Kod) Pojtanabuntoeng

Professor Thunyaluk (Kod) Pojtanabuntoeng is the Woodside and Chevron Chair in Materials and Corrosion Engineering at Curtin University. She holds a PhD in Chemical Engineering from Ohio University and an MSc in Petroleum Technology from Chulalongkorn University. Her research focuses on corrosion in oil and gas systems, including CO2 corrosion, Top-of-the-Line corrosion (TLC), and corrosion under insulation (CUI). Since joining Curtin in 2012, she has led industry-funded projects addressing practical corrosion challenges and is an active member of the Australasian Corrosion Association. She advocates for collaboration between academia and industry in corrosion science and engineering.
