Demonstration project with successful incorporation of Oscillating Water Column technology in Mutriku, in the North coast of Spain. First breakwater wave energy project in Europe.
The NEREIDA OWC projects pursues several specific objectives:
Eight OWC cells will be constructed to give an active collector length of close to 100 meters. Power take-off involves multiple turbine, each turbine being rated at 18.5kWe. Two turbines will be fitted to each OWC cell giving 16 turbines in total and a total installed power of 300kW.
The application of this technology at Mutriku will not only demonstrate the functional synergy between breakwaters and OWC systems but will do so in a location which, in contrast to previous European wave energy demonstrators, is in a urban location. There is good access to the OWC units via the breakwater and the application of the technology at these particular location will greatly increase the knowledge of the environmental acceptability of the system.
The integration of the wave energy converter into a dual or multi-purpose structure as a breakwater has the advantage of sharing the construction costs and reduces the environmental impacts resulting from integrating into other infrastructure. The project aims to bring wave energy technology closer to commercial exploitation by demonstrating the integration of the Oscillating Water Columns (OWC) technology into breakwaters, at more competitive costs.
