Presentation Abstract:
Steel pipelines are key components of the CO2 transportation infrastructure, which is critical for advancing Carbon Capture, Utilization, and Storage (CCUS) technologies. Efficient transportation of CO2 while minimizing transportation costs is critical, but this must be achieved without compromising the safety or performance associated with the pipeline infrastructure. CO2 is most efficiently transported in its dense phase or supercritical state, which presents unique challenges, such as the promotion of ductile running fractures that lead to extensive pipeline ruptures. Additionally, a key barrier to safe and reliable pipeline operation is the limited understanding of corrosion and mechanical performance of pipeline steels in supercritical or dense-phase CO2, specifically in the presence of impurities and increased flow capacity. This knowledge gap is particularly significant due to the lack of industrial experience in the transmission of anthropogenic CO2. Ongoing research is addressing these challenges by investigating the influence of metallurgical factors on steel degradation in CO2 environments. This seminar will highlight the latest research on the mechanical and corrosion performance of pipeline steels in these environments, introduce the recently established supercritical CO2 corrosion testing capability, and share key lessons learned from ongoing experimental studies.
Presenter:
Lawrence Cho is an Assistant Professor in the Department of Metallurgical and Materials Engineering at the Colorado School of Mines and a faculty member of the Advanced Steel Processing and Products Research Center (ASPPRC). He also holds an associate research appointment at the National Institute of Standards and Technology (NIST)-Boulder. Previously, he was a Research Assistant Professor at the ASPPRC and worked as a Materials Research Engineer at the NIST through the NRC Research Associateship program. His research focuses on the application of fundamental steel science to practical challenges related to the development of advanced steel for industrial applications. His recent interests include the design of cost-effective materials and energy-efficient industrial processes to support renewable energy systems, including carbon capture utilization storage (CCUS) and hydrogen service applications.
