This document specifies the requirements and recommendations for the transportation of CO2 streams from the capture site to the storage facility where it is primarily stored in a geological formation or used for other purposes (e.g. for enhanced oil recovery or CO2 use). This document applies to the transportation of CO2 streams by — rigid metallic pipelines, — pipeline systems, — onshore and offshore pipelines for the transportation of CO2 streams, — conversion of existing pipelines for the transportation of CO2 streams, and — transportation of CO2 streams in the gaseous and dense phases. This document also includes aspects of CO2 stream quality assurance, as well as converging CO2 streams from different sources. Health, safety and environment aspects specific to CO2 transport and monitoring are also considered in this document. Transportation of CO2 via ship, rail or on road is not covered in this document.
