What if we put wind turbines in the sky?

While the project may seem a little crazy at first glance, it has many advantages. First, its installation cost is much lower than that of current offshore wind turbines. The absence of a mast, replaced by a cable, and the reduced size of the float significantly reduce the cost of the structure. The system's high altitude allows it to capture more consistent and powerful winds than at the surface.

Another key advantage is the very short deployment time of less than a year, made possible by national expertise and a production chain located more than 90% in France. These factors mean that the cost of energy is expected to be equivalent to that of gas today and therefore very competitive, in a context of strong growth in energy demand at European and global levels.

“We are planning to enter the market in 2033 with, for the first year, around 30 aerostats spread across several offshore wind farms, then gradually increasing the volume deployed in France and internationally.”

Between now and then, a significant amount of research and development work needs to be carried out: sizing the structure, ensuring the stability of the float, testing the resistance of the materials, etc.
