A monster of 30 meters, something great and at the same time prodigious, that is sailing the world and that during the summer passed through the Mediterranean, all without consuming a drop of fuel. Energy Observer, is the giant 30×12.50 meter catamaran (pictured in the Corinth Canal) that sails in total silence. The mission of the incredible Energy Observer is to demonstrate that it is possible to navigate without traditional propulsion, thanks to a mix of renewable energy (solar, wind and hydro-eolic) and a double storage with hydrogen batteries produced on board with the electrolysis of sea water.
The first hydrogen ship in the world returned to Saint-Malo after 16 months and 10,326 nautical miles left aft, without emitting greenhouse gases or fine particles. Will self-produced hydrogen be the future of propulsion?
The future is today, you have to go “green” before it’s too late! The Energy Observer mission
The vision of Energy Observer of the future is very simple: it is possible to draw energy from nature, without damaging it and without wasting it. The goal is to spread this perspective with the whole planet in such a way that anyone becomes aware that it is possible. To do this, the team has undertaken a human and technological challenge with the Energy Observer: the first self-sufficient energy ship with zero-emission greenhouse gas emissions or fine particles fueled by hydrogen and renewable energy, thanks to the combination of energy

Without sun? Energy Observer is getting ready to sail in Northern Europe
After leaving Marseilles in March, the Energy Observer sailed for almost 6 months under almost optimal conditions the spring and summer sun to provide for its own needs, needing hydrogen at night or when it was very cloudy. The next Energy Observer route passes through Northern Europe: less sun, more wind, colder. This catamaran will have to be adapted to the new conditions that await it and on which the engineers and the team are already working:
- Optimize the surface and efficiency of photovoltaic panels
- Make the most of what the wind turbine offers and optimize hydro-generation.
- Improve the caloric recovery of fuel cells to store energy in the form of Nautic heat, the Paris international boat show.
