This call seeks to produce a digital atlas of 'investable' underground CO2 storage sites across the European Union and Associated Countries. Recognizing the need for clear pathways to mature CO2 storage sites to develop CCS value chains, the project aims to enhance transparency about potential CO2 storage capacities, injection capacities, and infrastructure. This will support market operators in planning investments and enable the implementation of large-scale storage hubs connected to shared CO2 transport infrastructure.

Projects are expected to identify and assess injection and storage capacities with a harmonized methodology, label potential storage sites according to their 'storage readiness level,' and develop plans for pre-licence appraisal in key regions. The initiative should consider environmental aspects and compare and rank identified storage sites using a common ranking scheme. Collaboration with national and regional actors managing the subsurface, such as geological surveys or competent authorities, is crucial. The project must demonstrate access to necessary data during implementation and may utilize existing resources like the European CO2 Storage Atlas and the Commission's Energy and Industry Geography Lab.
