Croatia releases first estimate of geological CO2 storage capacity for carbon capture projects

Croatia has published its first official estimate of geological CO2 storage potential, a key step for developing carbon capture and storage (CCS) projects in the region. The assessment identifies several deep saline aquifers and depleted hydrocarbon reservoirs that could collectively store millions of tons of carbon dioxide. This data is critical for companies planning CCS investments and for the country's broader decarbonization strategy under EU climate targets. The estimate gives project developers a clearer picture of where and how much storage capacity exists, which reduces uncertainty for carbon capture investments. For the Balkan region, this is a notable development because geological storage data has been sparse. The next step will be detailed site characterization and regulatory frameworks to actually permit injection operations. Without those, the estimate remains a theoretical number rather than a pipeline of real projects.
