Effects of CO2-stream impurities on CO2 transport and storage
Based on the application chosen (either transport or storage), projects have to deliver:
- Recommendations for design and operation of pipelines and/or ship offloading, including recommendations for public health and safety requirements and for protective and/or mitigating material and/or approaches and/or monitoring technology to avoid adverse effects on the integrity of the relevant transport infrastructure caused by impurities;
- Recommendations for public health and safety requirements and for protective and/or mitigating material and/or approaches and/or monitoring technology to avoid adverse effects on the integrity of the storage complex;
- Guidance and recommendations for technology providers, regulatory authorities, certification and standardisation bodies, and define and implement ambitious dissemination actions to promote the project results and support their uptake.
Projects can address, for example, the following issues:
- Transient flow modelling along the pipeline network and;
- Combined thermodynamic and corrosion modelling to predict corrosion rates under different conditions;
- Reactive transport and geochemical modelling of the storage reservoir in the near-well zone, including associated geological barriers to leakage;
- Generation of experimental data on the geochemical reactions of reservoir rocks, caprocks, well cements and fault seals exposed to impure CO2 under the span of pressure and temperature regimes relevant for planned and future storage projects in saline aquifers, depleted hydrocarbon reservoirs and or mafic and ultra mafic formations for mineral storage of CO2, to tune existing and/or new models;
- Generation of experimental data on thermophysical and corrosive properties of CO2-rich mixtures under CCS-relevant conditions, to tune existing or new models;
- Impact of impurities on various equipment (e.g. valves, gaskets, compressors, instrumentation), in particular on non-metallic components in the CO2 transportation system;
- Impact of impurities on the physical behaviour and geochemical interaction of the CO2 stream within the storage complex;
- Impact of achieving very low impurity levels on the relative costs of competing capture technologies and the trade-off with costs for CO2 transportation and geological storage;
- Development of a systematic method to understand limits for impurities and define specifications for transport and storage infrastructure.
The use of the European Research Infrastructure for CO2 Capture, Utilisation, Transport and Storage ECCSEL is encouraged but not mandatory.
Selected projects are encouraged to seek synergy with possible standardisation activities performed by CEN, CENELEC, ISO and ETSI on pre-normative research for standards for the transport and permanent storage of carbon dioxide[[ Open call for proposal, 6 June 2024. See: Support to Standardisation activities performed by CEN, CENELEC and ETSI - European Commission (europa.eu)]].
International cooperation is encouraged, in particular with projects or partners from the United States.
