Energy Observer in Greece: between launching field investigations and partner events

1-7 September

It is to go beyond the promises, and understand their limits, that we chose Greece as the first stopover of our mission, and began our first on-the-ground investigations.

Launching field investigations

In Kavala, we met the teams behind the Prinos project. Out at sea, an oil field that has been in operation since the 1980s is being transformed into a vast carbon reservoir. Watching this infrastructure reinvent itself before our eyes is a striking experience: turning a fossil fuel site into a climate vault.

With an announced capacity of 3 million tonnes of CO₂ stored per year by 2028, Prinos embodies the ambition of giving a second life to the legacies of the past. What makes this visit all the more memorable is knowing that this carbon will soon come from neighbouring industrial plants, from regional cargo shipments by sea, and even from the ambient air through direct air capture, a still-fragile technology being piloted here as early as 2026.

Prinos is not just a technical project, but a full-scale laboratory.

Our partners join forces

Our Greek stopover was also marked by a significant moment of connection and exchange, through an event co-organised by two of our official partners, Groupe Qair and Natixis Corporate & Investment Banking. We were pleased to take part alongside authorities, experts, and key players in the energy transition. A unique opportunity to showcase how synergies between the maritime sector, renewable energies, and finance can accelerate decarbonisation.

We also had the pleasure of welcoming other partners on board, including Chart Industries and Groupe Roulier, for exclusive visits and sailing outings.
