EnEarth has welcomed a positive opinion issued by the European Commission’s Directorate-General for Climate Action (DG CLIMA), concerning the application for a permit to permanently store carbon dioxide (CO₂) in the Prinos reservoir, in the northern Aegean.

The Commission’s assessment highlights the quality and completeness of the technical studies conducted by EnEarth Greece, including geological evaluation of the storage site, analysis of reservoir behavior, and the project’s monitoring framework.

According to the opinion, these studies demonstrate a high level of understanding of both the proposed storage location and the broader storage complex. The Commission further confirms the suitability of the Prinos geological formation for safe, permanent CO₂ storage and recognizes the advanced technical maturity of the project.

The Commission’s opinion forms part of the formal consultation process between Brussels and Greece’s competent authority, the Hellenic Hydrocarbon and Energy Resources Management Company (HEREMA), under the EU directive governing geological CO₂ storage. While non-binding, the opinion represents a crucial final step toward the granting of a storage permit, with the ultimate licensing decision remaining under HEREMA’s jurisdiction.

The Prinos CO₂ storage project aims to provide a safe and permanent geological solution for industrial carbon emissions, supporting both Greek and European climate targets while enabling decarbonization in hard-to-abate industrial sectors. The first phase of the project foresees the storage of one million tonnes of CO₂ annually. A planned second phase would expand capacity to approximately 2.8 million tonnes per year.

The Prinos facility is regarded as strategic infrastructure for Greece and the wider region, positioning the country among Europe’s leaders in tackling the impacts of the climate crisis through advanced carbon management solutions.
