European investment atlas of potential CO2 storage sites

• Enhanced transparency and availability of CO₂ storage sites across the EU and Associated Countries
• A digital, public-facing atlas detailing potential storage and injection capacities, geomechanical characteristics, and pressure interference zones
• Clear identification of capacity gaps relative to the NZIA 2030 target of 50 MtCO₂/year
• Prioritised list of high-potential regions and sites with pre-licence appraisal plans to accelerate site maturation
• Standardised ranking and techno-economic framework to guide market operator investment decisions
• Evidence base to support the development of large-scale storage hubs linked to shared CO₂ transport infrastructure
• Strengthened collaboration between EU bodies, national geological surveys and industry, facilitating coordinated planning of CCS value chain infrastructure

Proposals must: 1. Produce a comprehensive digital atlas of investable CO₂ storage space for EU Member States and Associated Countries 2. Build on and close data gaps in the European CO₂ Storage Atlas and use the Energy and Industry Geography Lab as appropriate 3. Identify and assess, via a harmonised methodology, injection and storage capacities of existing and planned sites and benchmark against the NZIA target of 50 MtCO₂/year by 2030 4. Map and prioritise key regions for pre-licence appraisal and formulate detailed appraisal plans region by region 5. Label each potential site with ‘storage readiness levels’ per the GSEU standard and cross-reference with public data sources 6. Develop and apply a common ranking scheme, including techno-economic criteria, to compare and prioritise sites 7. Incorporate geomechanical site characterization and pressure interference effects into storage capacity estimates 8. Assess and report on environmental (e.g., sealing integrity, induced seismicity) and security (e.g., containment risk) aspects 9. Demonstrate secured access to all required datasets (public and proprietary) at proposal stage and maintain data access arrangements 10. Engage and collaborate with relevant national/regional subsurface authorities (e.g., geological surveys, competent authorities) throughout the project
