Abstract
A qualitative and quantitative analysis is presented of two renewable marine energy sources: wave energy and offshore wind energy in the Gulf of Cádiz (south of Spain) putting special focus in their joint exploitation. From numerical model simulations of time series of wave and wind data, spanning the years from 2006 to 2020, provided by Puertos del Estado, we carried out a characterization of both resources for the studied region. The model was validated with time series from two oceanographic buoys. The temporal and spatial variability of both resources was also studied through the construction of wind and wave roses, and several maps, where the seasonal mean values of wave and wind power were evaluated. Two high-energy episodes that took place during the study period were selected: the storms Emma and Elsa, and their power peaks were analyzed. The main conclusion of this work indicates that there is an area of the Gulf, on the eastern side of the region, and above the 300-meter isobath, where both resources show significant power values, and it would be the ideal place for the joint exploitation of the two resources.
