This study aims to assess the potential of wind, wave, and collocated hybrid energy systems using the Siemens SWT 6.0-154 wind turbine and the CorPower Ocean wave energy converter in the northeastern (NE) Mediterranean Sea. The ERA5 wind data from 1994 to 2023 and wave data derived using a calibrated SWAN wave hindcast model were used to compute the available wind and wave energy resources. Based on the long-term wind wave database, the collocated and simultaneous hourly wind/wave power outputs for the hybrid system were computed over a 30-year period by averaging their capacity factors (CF) under an equal rated power assumption, which ensures identical nominal capacities for both sub-systems to provide a balanced comparative baseline. The originality of this study lies in the consideration of co-located and simultaneous wind and wave power calculations for hybrid system. The power generation potential of the wind and wave energy converters were evaluated considering four main aspects: wind and wave energy productivity, wind and wave energy variability, wind and wave energy supply stability, and wind and wave synergy. Additionally, the hybrid energy converter was evaluated by combining the hourly generated wave power outputs using optimal CorPower scales with the hourly generated wind power outputs, considering the same maximum capacity factor for both systems. Theoretical hybrid energy system was assessed spatially and subsequently compared against the offshore wind system. Four indices were used to investigate the synergy between two energy sources in the hybrid system. According to the results, the 20%-30% downscaled CorPower Wave Energy Converter (WEC) offers better performance in the NE Mediterranean compared to the original scale, allowing for a considerable improvement in the hybrid system's capacity factor. Besides, the hybrid system demonstrated more attractive resource performance across the entire study area compared to separate offshore wind converters, with a considerable capacity reaching 45% on the eastern coast of Crete Island. These findings provide a crucial roadmap for investors and policymakers to optimize offshore renewable energy planning in the Mediterranean basin, demonstrating that site-specific WEC downscaling is key to unlocking the region's hybrid potential.
