"IMPACTS - The impact of the quality of CO2 on transport and storage behaviour will underpin the realisation of the EU CCS European Industrial Initiative implementation plan by developing knowledge and technology needed for Carbon Dioxide Capture, Transport and Storage (CCS) pilots and large-scale demonstrations. IMPACTS is linked to demonstration projects, and will therefore benefit from realistic data, adequate framework conditions and relevant cases provided by the projects.The objective of IMPACTS is to develop the CO2 quality knowledge base required for defining recommendations to ensure safe and reliable design, construction and operation of CO2 pipelines and injection equipment, and safe long-term geological storage of CO2. This will support the objectives of the Innovation Union and the competitiveness of the European CCS industry.The work will combine experimental and modelling work and, among others, the following scientific and technological objectives will be pursued:- To quantify fundamental properties of relevant CO2 mixtures. This includes phase behaviour, thermodynamics, fluid flow and chemical reactions.- To reveal the impacts of relevant impurities in the CO2 stream on the design and operation of the transport and storage infrastructure through techno-economic assessments.- To derive CO2 quality issues while considering integrity of the whole CCS chain.- To provide recommendations for optimized CO2 quality on a case-by-case basis in the form of tolerance levels, mixing protocols and material selection.- To build knowledge critical for implementation of optimized safe and cost-efficient transport and storage of CO2."
