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.

This technical revision includes an expansion of scope to include a new clause on quantification and verification and updated definitions as beneficial. To facilitate ISO/TC265’s desire to have this guidance publish as soon as possible, this revision will comprise the addition of a quantification and verification of geological storage of CO2 clause as well as the correction of errors or inconsistencies only. Changes to other clauses in the Standard are not proposed as part of this revision, other than those necessary to incorporate quantification and verification.

1. Scope: This document is a part of a series of standards for carbon dioxide (CO2) capture. It specifies methods for measuring, evaluating and reporting the performance of CO2 capture plant connected to a CO2 intensive plant, and which separate CO2 from the CO2 intensive plant exhaust gas in preparation for subsequent transportation and geological storage. In particular, it provides a common methodology to calculate specific key performance indicators for the CO2 capture plant, requiring the definition of the boundaries of a typical system and the measurements needed to determine the KPIs. 2. Policy of work: The series of standards for carbon dioxide capture will be done based on the following fundamental policies: (1) The standards and requirements being developed in the series will depend on the maturity of the content and its practical use to stakeholders. (2) Standards in the series will build on the previous standards. (3) Standards for CO2 capture lend themselves better to a series of individual standards rather than a single comprehensive standard because of the maturity of the technologies and the process differences in power and different Energy Intensive Industries (EII).
