Greece's Prinos CO2 Storage Project Takes a Major Step Forward With FEED Contract

Kent, a global engineering and services company headquartered in Dubai, has been awarded a front-end engineering design (FEED) contract by EnEarth, the carbon storage subsidiary of UK-based oil and gas company Energean. The contract covers the Prinos CO2 Storage Project in northern Greece, the first CO2 storage project in the Mediterranean to secure both an environmental permit and a storage permit.

The storage permit was issued in late February 2026 by HEREMA (Hellenic Hydrocarbons and Energy Resources Management Company), Greece's national licensing authority for geological CO2 storage, and is valid for 25 years. The project carries a total investment of EUR 1.2 billion and has been listed on the European Union's Projects of Common Interest (PCIs) program, with EUR 270 million in funding secured from the EU's Connecting Europe Facility and Greece's Recovery and Resilience Plan 2.0.

How the Prinos CO2 Storage System Works

CO2 from industrial emitters will be shipped via marine carriers to a new terminal at the onshore Sigma plant near Kavala, where it will be temporarily stored, conditioned, and pumped through a new subsea pipeline to a dedicated injection platform within the existing Prinos complex. The CO2 will be injected into the Prinos saline aquifer, stored at approximately three kilometers beneath the seabed.

Kent's scope covers the FEED for the new CO2 handling and storage facility, including reception, storage, transport, and injection infrastructure. This phase will define the full technical scope and execution strategy for the project.

Paul Wetton, Vice President of UK Engineering Services at Kent, said: "Prinos represents one of Europe's most strategically important carbon storage developments, and this FEED award marks a meaningful step toward enabling large-scale industrial decarbonisation in Greece and across the EU."

A Two-Phase Approach to Scaling Up

The project is being built out in two phases. Phase 1 focuses on repurposing the existing Prinos infrastructure to reach an injection capacity of 1 million tons of CO2 per year, with the facility capable of receiving CO2 in compressed form by 2026–2027. Phase 2 targets an expanded capacity of 2.8 million tons per year of liquid CO2 by 2029–2030, with operations planned to continue for approximately 20 years.

The Prinos field, the only producing oil and gas field in Greece, was discovered in 1974 and has been in production since 1981. EnEarth is now working to repurpose that infrastructure into a large-scale carbon storage hub.

Nikolas Rigas, Head of Carbon Storage at the Energean Group, described the FEED award as one of the most important milestones yet, noting that the more than EUR 1 billion investment is progressing rapidly toward execution.

A Cornerstone of Mediterranean CCS

Prinos aligns with the Mediterranean CCS Strategic Plan developed jointly by France, Italy, and Greece, which aims to build the first industrial-scale CO2 storage hub in southeastern Europe. With permits secured, EU funding in place, and engineering now underway, the project is moving faster than most European CCS initiatives have managed to date.
