scope:

This document specifies additional requirements and recommendations not covered in existing pipeline standards 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 EOR or CO₂ use).

This document applies to

- 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,

- pipeline transportation of CO₂ streams for storage or utilization, and

- transportation of CO2 in the gaseous and dense phases.

The system boundary (see Figure 1) between capture and transportation is the point at the inlet valve of the pipeline, where the composition, temperature and pressure of the CO₂ stream is within a certain specified range by the capture process or processes to meet the requirements for transportation as described in this document.

The boundary between transportation and storage is the point where the CO₂ stream leaves the transportation pipeline infrastructure and enters the storage infrastructure.

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 considered.
