D1 – Report on the development, intercomparison, operating ranges, and traceability of intermediate-scale and large-scale flow standards for gaseous CO2 to enable the calibration of flow meters
D2 – Good practice guide for CCS fiscal metering, including recommendations to advance the application of CCS fiscal metering solutions, which will contribute to traceable and accurate flow measurement (uncertainties below 2.5 %)
D3 – Good practice guide for the measurement of nitrosamines in post-combustion flue gas in order to enable the direct determination of emissions of CO2 and to address the measurement of air pollutants resulting from the capture process, such as degradation products from capture solvents
D4 – Report on the options for the measurement and reporting of emissions to air from different stages of the CCUS process and the performance and capabilities of techniques to monitor emissions into the environment through carbon capture processes, infrastructure (leaks), or geological storage
D5: Paper on new Primary Reference Materials for gas composition for carbon capture, utilisation and storage and how they support industry and meet the technical specifications of European manufacturers, including a summary of the validation and stability data of the mixtures produced, submitted to an open-access, peer-reviewed journal
D6 – Report on new methods for the chemical testing of capture solvents, including purity, stability and CO2 uptake to support European industries in understanding the degradation and purity of CO2 and key impurities and ensuring efficient operation and utilisation of CO2
