While traditional breakwaters dissipate wave energy, the new Dikwe system transforms it into electricity. This French innovation combines coastal defense and energy productionThis French innovation combines coastal defense and energy production, opening a new avenue in the use of marine resources.
Dikwe is the result of a collaboration between GEPS Techno, the Legendre Group and the Ifremer marine research institute. Unlike conventional breakwaters, this infrastructure incorporates a movable fin connected to a conversion device that, driven by the waves, generates energy. Its purpose is to protect harbors and coasts while producing clean electricity. clean electricity.
Dikwe system prepares for full-scale testing
Since 2012, Ifremer and GEPS Techno have been working on digital models, 1/15 scale tests and then a 1/4 scale prototype installed in the Bay of Brest. The last stage involves a full-scale installation in Boulogne-sur-Mer, scheduled to be commissioned by the end of 2025. In addition to assessing energy performance, its environmental impact on the marine environment is being studied.
The initiative has led to the creation of the Wave-OP joint venture, dedicated to promoting this solution in ports and coastal areas. The strategy seeks to replicate the model in different geographic contexts, integrating hybrid technologies technologies adapted to local conditions. This proposal responds to the challenges of the blue economy and the need for resilient and sustainable infrastructures.
Wave energy in action
The key to the system lies in its ability to adapt to the natural movement of the sea. Each installed fin captures the kinetic kinetic energy of the waves and converts it through internal mechanical systems, all without disturbing the balance of the ecosystem. This makes it possible to integrate energy production into essential port functions.
Dikwe represents an evolution in the design of maritime defenses. It is not only about resisting the sea, but also about collaborating with it. GEPS Techno’s accumulated experience and Ifremer’s scientific strength position this technology as an emerging benchmark in coastal energy solutions.
