Carbon dioxide quantification and verification across the CCS Value Chain

Scope

This Standard will describe the measurement methodologies to quantify the mass of CO2 and CO2
stream (see ISO 27913 for definition of CO2 stream and ISO 27914 for quantification and verification
of CO2 related to geological storage) transferred across the CCS chain and to measure the level of
impurities in the CO2 stream.
This standard will encompass the entire Carbon Capture and Storage (CCS) chain, spanning from
the initial capture, transportation and subsequent injection into a geological reservoir. It will also
include measurement methods for batch transportation such as shipping, truck, and train
loading/unloading.
The standard will provide guidelines on available technologies for measuring the flow rate, mass of
CO2 or quantity of CO2 in mass flow rate, and composition of the CO2 stream. Moreover, will
establish the technical requirements for the instrumentation employed in the measurement process
and the allocation methods across the integrated value chain including metering and reconciliation.
The standard will also delineate the methodologies and requirements for quality assurance and
verification. This will ensure the establishment of measurement quality before installation and its
consistent maintenance throughout the operational phase in a standardised way.
The standard will provide standardised methodology for quantification and accounting of the carbon
dioxide transferred across the CCS chain.
It should be noted that the standard will not detail requirements for greenhouse gas emission
reporting, which are covered by existing standards and by national regulations.
It should be noted that this standard will cover the measurement of carbon dioxide streams at the
geological storage injection points, but will not cover the measurement, monitoring and verification
(“MMV”) for integrity of the storage complex which are covered in subsurface related standards and
therefore will be dealt with in the Working Group (WG) for Storage..
The primary objective of this report is to produce precise, standardized technical guidelines and
specifications that underpin the implementation of regulations, commercial contracts, and fiscal
transactions in the realm of CCS.
