Measurement of CO2 streams - Sampling and analysis for pipeline transportation

Scope

This document specifies requirements and recommendations for measuring the composition of CO2 streams during post capture pipeline transportation.
The primary objective of this document is to establish standardized technical requirements and recommendations necessary for implementing regulations, commercial contracts, inventory ownership and fiscal transactions within the framework of Carbon Capture and Storage (CCS).
This document includes measurements up to the storage injection points but does not cover Measurement, Monitoring, and Verification (MMV) once the CO2 has entered the geological storage complex.
The differentiation between biogenic and non-biogenic CO2 in a CO2 stream is recognized as highly relevant for accounting purposes. However, the measurement methodologies for the biogenic CO2 fraction fall outside the scope of this document, which covers post-capture pipeline transportation. This document is not intended to differentiate between biogenic CO2 and CO2 produced from non-biogenic sources.
