The scale of proposed carbon dioxide (CO2) capture and storage (CCS) chains also draws attention to the hazards posed by the transport mode, enabling the link from source to sink. As such, the adverse consequences of an accidental release from transport pipelines or other equipment containing CO2 at high pressure in a dense-phase (supercritical or liquid) state are (re)considered in theory and in practice. Several experimental observations of large-scale CO2 releases have been made, and yet the physics and thermodynamics involved are not fully understood. The work presented here provides a database focused on the specificities of the release and the dispersion of the carbon dioxide cloud in case of substantial variations of storage (temperature and pressure) and discharge conditions (nozzle size).
