Share: A new energy converter Symphony Wave Power (Netherlands) can be used in the ocean to generate energy directly from the water. It will be launched in 2026. The system has at its disposal a point absorber that reacts to the movement of waves from all directions. The absorber is capable of capturing and converting significant amounts of wave energy into useful energy, writes interestingengineering. com. Unlike surface buoys or floating structures, the system is completely submerged under water.

Each of its units consists of two main components: a fixed central core attached to the seabed, and a hull that moves vertically in sync with the movement of the waves. A flexible rubber membrane filled with liquid and air is placed between the components. As the waves pass over the energy converter, pressure changes cause its housing to move up and down, causing the fluid to pass through a bidirectional turbine that drives the generator.

Thanks to fine-tuning, the internal "spring" of the system is adjusted so that its own frequency corresponds to the rhythm of the waves. The resulting resonance enables the system to move in harmony with the waves, maximizing their conversion to energy. This technology can generate clean and stable electricity, which can then be directly fed into the underwater DC grid. The system provides 5 times higher efficiency compared to traditional non-resonant designs.

According to the company, each device is compact, consists of only two main moving parts and is made from recyclable materials. Once commissioned, the system is expected to operate for many years with virtually no maintenance. This should significantly reduce long-term costs and impact on the environment. Symphony Wave Power says up to 60 devices can be connected underwater to form energy clusters capable of generating up to 6 megawatts of electricity.
