Session 25. Oral Presentation for: Benchmarking CO2 and methane dispersion from high-pressure pipelines

Presented on 21 May 2026: Session 25 The rapid development of carbon capture and storage (CCS) projects has increased the need for robust process safety guidance for the transport of carbon dioxide (CO2) in high-pressure pipelines. While the dispersion behaviour of natural gas releases is supported by extensive industry experience, equivalent understanding for CO2 – particularly under high-pressure pipeline release conditions – remains limited. This study benchmarks the dispersion behaviour of C
