Exploiting offshore wind and solar resources in the Mediterranean using ERA5 reanalysis data

Commercial electricity production from marine renewable sources is becoming a necessity at global scale. Offshore wind and solar resources can be combined to reduce construction maintenance costs. In this respect, the aim of study two-fold: i) analyse offshore resource their variability in Mediterranean Sea annual seasonal scales based on recently published ERA5 reanalysis dataset, and; ii) perform preliminary assessment some important features complementarity, synergy, availability examined using an event-based probabilistic approach. A robust coefficient variation introduced examine each joint implemented for first time evaluate potential. The association between by introducing measure correlation, along with Pearson’s r Kendall’s ? correlation corresponding results are compared. Several metrics used degree complementarity affected intermittency issues. Areas high potential low both include Aegean Alboran seas, while significant synergy (over 52%) identified gulfs Lion, Gabes Sidra, northern Cyprus Isl. advantage combining these two highlighted selected locations terms monthly energy production.
