The paper “Supercritical/dense-phase CO2 pipeline leakage diffusion experiment and hazard distance prediction method” has been published in the Journal of Pipeline Science and Engineering.

The authors suggest that while several large-scale CO₂ pipeline leakage experiments have been carried out in the international arena, and extensive research conducted on the quantitative description of CO₂ leakage and diffusion behaviour from the perspectives of experimentation, numerical solution, and model calculation, there have been few studies on quantitative risk assessment (QRA) and hazardous distance delineation using leakage diffusion data. In particular, they say, no unified conclusion has been reached regarding the delineation and calculation methods for hazardous distances.

The current study aims to close that gap by conducting CO₂ leak diffusion experiments, verifying diffusion models, calculating hazard distances, and establishing prediction models.
