The first sample to test for the presence of carbon dioxide (CO2) in the Gulf of Kavala was taken in November 2024, while a second sample was taken in March, in view of the implementation of the carbon dioxide storage investment in Prinos developed by EnEarth, a subsidiary of Energean.

The samples were taken using the research vessel "Filia" of the Hellenic Centre for Marine Research, within the framework of the COREu pilot research programme. The purpose of the samples is to record the natural occurrence of carbon dioxide in the Gulf of Kavala and the parameters that affect this, so that there is a comparison sample during the environmental monitoring of the storage project, when it will be put into operation from 2027 onwards.

Energean posted a video about the project on its YouTube channel (https://www.youtube.com/watch?v=3ijHjr3GW7I&t=1s).

The carbon dioxide storage project in Prinos, together with the COREu pilot project, are part of the European Union's overall climate policy and the effort to support industries in reducing their carbon dioxide emissions, limiting the related costs that they bear and promoting the transition to a more sustainable world.

The COREu administrator is the independent organisation SINTEF and the programme involves approximately 40 partners, such as universities, research centres, administrative authorities and businesses from Europe.
