The team

Aboard the boat, skippers and bosuns guide the expedition embarked on by this extraordinary vessel; mechanics, technicians and engineers ensure the on-board systems perform well, whilst the reporters and cameramen document the stopovers and share Energy Observer’s encounters with advocates for change.

Over time, the Energy Observer project has become a genuine advocate for change by creating its own research and development firm, Energy Observer Developments. Its objective? To use these years of navigational expertise and the knowledge acquired by its engineers to design, assemble and distribute zero-emission energy systems on an industrial scale.

Here, where the vessel is testing these technologies in extreme conditions, EODev (Energy Observer Developments) is responsible for rolling them out on a grand scale, thus making them accessible to all.

The leaders of the expedition

  • Victorien Erussard

    Captain and founder

    There is no lack of information on Victorien's exemplary career, yet it is not easy to paint a portrait of him: in barely 40 springs, it is difficult to summarize his life in a leaflet. Born with his feet in the water of the corsair city (Saint-Malo), his beginnings in sport sailing are just like the rest of the story: punchy and passionate.

    With a Route du Rhum at the age of 26 that ended on the podium in a Multi50 (whereas he had not spent a single night at sea in a racing boat before!), his career as a top-level athlete got off to a strong start. Even if the call of the open sea would make him sail for many years with an impressive list of achievements, a more pressing call would make him change course: that of the planet, in perdition both on land and at sea. Sketches of the project that will become Energy Observer date back to 2013, with several developments before becoming the renewable energy and hydrogen laboratory ship we know today.

  • Jérôme Delafosse

    Expedition leader and film director

    With more than 20,000 hours under the sea and 800 shark dives to his credit, Jérôme has crisscrossed the world for a quarter of a century from the bottom of the oceans. Professional diver, press photographer, expedition leader, his multiple lives have led him from the sunken palace of Cleopatra in Alexandria to another world buried underwater: the abyss, camera in hand at a depth of 1,000 meters.

    The face of the program Les Nouveaux Explorateurs on Canal+ and Travel Channel for nearly 8 years, his change of course came with Les Requins de la Colère, a 90-minute documentary on saving sharks broadcast in prime time on Canal+. Filming, documenting, raising awareness: his awareness took him on the road to Victorien, then to the beginnings of the Energy Observer project.

    One at the helm, the other behind the camera: if sailors are known to be more at ease on the water than in the depths, Victorien has found the perfect co-leader to document this unique odyssey around the world.

Godfather and godmother

  • Nicolas Hulot

    Nicolas Hulot, Former Minister, founder of the Foundation for Nature and Mankind and Energy Observer Godfather

    "Energy Observer is more than just a boat; it is a demonstrator and collector of solutions. It designs a future that has already begun. A long-term and evolving project that wishes to create a wave of positive energies."

  • Florence Lambert

    Florence Lambert, director of the CEA and Energy Observer Godmother

    "Today, energy is experiencing a true revolution by integrating an increasingy number of renewable energies with different vectors: electricity, heat, and hydrogen. There are real technical challenges in connecting these fluxes, and it is even more ambitious to try this on a vessel. Therefore, Energy Observer is a foreshadowing of tomorrow's energy networks on earth."
