The issues surrounding CO2 specifications and conditioning requirements were discussed in both the capture and transport sections. This was identified as a cross-cutting issue that will have impacts on the entire CCS chain. Lessons learned from existing CO2 transport projects have highlighted the importance of these technical considerations as CCS hubs continue to develop in the future, and as Members shift to operating on transport and storage models. The remaining unknowns on conditioning CO2 have become increasingly important.

There was a need to reconcile ongoing activities and publications within this space in order to understand where gaps or areas requiring further development. Important elements discussed include factoring in local gathering systems and multiple CO2 specifications from various emitters in hub concepts. Balancing stringent conditioning requirements vs. installing higher specification of pipelines/aggregation networks to account for a range of impurities was a primary driver.

This repository of academic papers offers an overview of Carbon Capture and Storage technology, encompassing both technical and socio-economic aspects. Several papers delve into the complexities of CO2 specifications for transport and storage, standardized measurement techniques, and the policy challenges surrounding CCS deployment. Additionally, the repository provides insights into the practical challenges encountered during the operation of a large-scale CCS project, particularly regarding public perception and stakeholder engagement. However, while the repository offers a solid foundation for understanding CCS, it lacks information on specific discontinued projects and a comprehensive list of ongoing projects globally. Further research into these areas would provide a more complete picture of the current state of CCS development and deployment.

Accessing detailed project data from CCS projects, encompassing layouts, configurations, modality, materials, purity, phases, and lessons learned, would offer invaluable insights for researchers, technology developers, and policymakers alike.
