An Aid Decision Tool for Implementing Wave Energy Devices on the Coast
International Journal of Sustainable Energy Development
A decision support tool for the selection of suitable areas is proposed in this paper for wave energy projects. It is based on a multi-criteria assessment methodology that considers physical, environmental and socioeconomic constraints. Criteria for site selection can include a large number of parameters, such as bathymetry and sea bottom. Additional factors (e.g. technological constraints, administrative and logistics conditions) can be added according to data availability; weight assigned for
... weight assigned for the different parameters can be easily adapted to suit the requirements of specific devices and installation procedures. The proposed method is applied to the French Atlantic Coast. Results show appropriate areas for the best locations for implementing a wave energy farm. French Brittany and the southern part of French Coast appear to be most suitable for wave energy devices deployment, not only from an energy point of view. The tool has been developed and tested over a large area. It can also be used in specific areas, with smaller scale, if geospatial data with good resolution are available. The multi-criteria analysis tool described above has been developed with an emphasis on offshore areas (depths going from 20 to 200m). The systems that are targeted for such areas are WECs that have been developed to extract energy from the deeper waters offshore or nearshore. Examples of such systems are attenuator WECs (e.g. Pelamis Wave Power, Scotland), oscillating wave surge converters (e.g. Oyster wave energy converter by Aquamarine Power, Scotland) or rotating mass (e.g. SEM-REV prototype, France).
