Dutch startup Symphony Wave Power has successfully completed dry-running tests of its underwater wave energy converter, a breakthrough that could mark a before and after in offshore power generation. Unlike traditional floating buoys, its system operates completely underwater, without disturbing the coastal landscape or relying on the size of waves.
How does the system work?
The technology developed by Symphony captures the pressure variations generated when a wave passes over the device, located at a depth of about six meters, which activates an internal hydraulic mechanism that drives a bidirectional turbine, transforming the swaying of the sea into electricity. sea into electricity.
The secret of the system lies in resonance, as the device can adjust its natural frequency to synchronize with the prevailing waves, maximizing energy harvesting without the need for additional mechanical components.
What are the advantages of the device?
Symphony’s system has significant advantages over other marine technologies, for example:
- Generate 300% to 500% more energy than traditional wave energy solutions, even with small waves.
- It consists of a fixed core anchored to the seabed and a mobile hull connected by a flexible rubber membrane that seals, dampens and protects the system from overloads. In addition, it incorporates a patented electronically controlled turbine that minimizes vibrations and prolongs the life of the equipment.
- Thanks to the modularity of the system provided by the “E-Box”, a submerged electronic box that controls up to six central turbines, the system can be installed at different depths with different types of waves.
Deployment in the North Sea
To bring the technology to the open ocean, Symphony Wave Power has signed a memorandum of understanding with ONE-Dyas, the leading private energy exploration and production operator in the Netherlands. This agreement will facilitate the deployment of the first systems in the North Sea in 2026, a strategic area for European renewables.
On the other hand, the official presentation of the developments is scheduled for November 2025, during the Offshore Energy Exhibition & Conference (OEEC) in Amsterdam, one of the key events of the marine sector in Europe.
