Energean, EnEarth, and Halliburton discuss the potential upgrade of the Prinos CO2 Storage capacity

In a recent meeting held in Athens, officials from Energean, EnEarth, and Halliburton discussed the next steps required to verify the potential upgrade of the Prinos CO2 storage capacity.

The project is initially designed to operate with a capacity of 1 million tons of CO2 per year in its first phase. The partners will now proceed with the necessary studies to determine the feasibility of increasing this capacity to 3 million tons per year.

Halliburton, a U.S.-based provider of technical services and products to the energy industry, has been involved with the Prinos fields since their early development. The company conducted a study assessing the Prinos basin's suitability for CO2 storage and supported EnEarth in submitting an application for a storage permit to HEREMA (Hellenic Hydrocarbons and Energy Resources Management).

The Prinos CO2 Storage project, located in the Gulf of Kavala in northeastern Greece, has been included in the EU’s 6th List of Projects of Common Interest. The project is expected to become operational in the first quarter of 2026.
