“…The combined exploitation of offshore wind energy and wave energy has several advantages, including enhanced energy yields, improved predictability, smoothed output power, costeffectiveness, and environmental benefits [26][27][28]. In recent years, numerous countries have conducted comprehensive resource assessments of offshore wind and wave energy to develop combined wind-wave power generation systems [29][30][31][32][33][34][35][36][37]. Based on their foundation and layout, combined wind-wave power generation systems can be classified as follows [26]: co-located (Figure 1a), island systems (Figure 1b), and hybrid systems (Figure 1c).…”

Based on the mutual compensation of offshore wind energy and wave energy, a hybrid wind–wave power generation system can provide a highly cost-effective solution to the increasing demands for offshore power. To provide comprehensive guidance for future research, this study reviews the energy conversion and coupling technologies of existing hybrid Wind–wave power generation systems which have not been reported in previous publications. The working principles of various wind and wave energy conversion technologies are summarised in detail. In addition, existing energy coupling technologies are specifically classified and described. All aforementioned technologies are comprehensively compared and discussed. Technological gaps are highlighted, and future development forecasts are proposed. It is found that the integration of hydraulic wind turbines and oscillating wave energy converters is the most promising choice for hybrid wind–wave power extraction. DC and hydraulic coupling are expected to become mainstream energy coupling schemes in the future. Currently, the main technological gaps include short their operating life, low energy production, limited economic viability, and the scarcity of theoretical research and experimental tests. The field offers significant opportunities for expansion and innovation.

“…The joint development of wind and wave energy is favored by sea areas with moderate and neutral resource density. In the Mediterranean, with moderate meteorology and sea state, scientists extracted the area related to a poor correlation between wind and wave [7,12]. For the first time, Wan et al [13] assessed the joint development potential of the offshore wind and wave generation in the South China Sea (SCS), taking into account hybrid installed capacity.…”

“…By revealing the occurrence tendency and mechanism of independent changes of amplitude or direction of the wind and wave, it not only provides a basis for joint assessment of offshore renewable energy but also helps to understand the spatiotemporal characteristics and variation mechanism of wind and wave climate and enriches the knowledge system of climatic dynamics under different terrains. Clustering analysis has been employed to holistically describe climatic wind-wave conditions in the Mediterranean [7,12], the northwest Pacific coast [4], and the global ocean [14] from the standpoint of energy utilization. Environmental data are statistically examined in some of these studies to identify local and temporary circumstances of weak wind-wave correlation, hence promoting optimal sites for combined energy projects [7].…”

“…Environmental data are statistically examined in some of these studies to identify local and temporary circumstances of weak wind-wave correlation, hence promoting optimal sites for combined energy projects [7]. Furthermore, researchers created a process to determine the quality of the co-exploitation of the two energies using multivariate approaches on the meteorological data of wind and wave [12]. Recently, an integrated monitoring system was deployed on an uninhabited island, Dongluo Island, Hainan, in the northwestern SCS.…”

Combined wind and wave power generation has advantages such as energy synergy and complementarity and will play a leading role in the integrated development of offshore renewable energy. From the perspective of joint energy development, this study focuses on the meteo-climatic wind and wave conditions in Dongluo Island, Hainan, in the South China Sea. Based on the concurrent measurement from in situ monitoring system, hourly data from June 2020 to September 2021 are used to reveal typical climate characteristics associated with the weak (inverse) correlation between wind and wave. The energy flux density of wind and wave are also assessed to describe the energy pattern. Principal component analysis (PCA) shows the wind parameters contribute a larger variance to the matrix of the wind–wave dataset than the waves, suggesting a lower stability of the wind climate. The first three components via PCA are then classified into five clusters to represent different climatic characteristics. Among them, the dominating cluster symbolizes a climatic circumstance with weaker winds and waves below normal. This cluster, evenly distributed in different seasons, shows the lowest wave–wind correlation, suggesting a favorable condition of the synergy of the two energies throughout the year. The clusters with the second and third largest sample sizes are mainly dominated in spring and winter, respectively. The magnitudes of the wind and wave parameters in these two clusters yield to a relation of “as one falls, another rises”, implying a high interest in complementarity between the two resources to a certain extent. The energy features inferred by meteo-climatic clusters are further verified by direct assessment of energy density. There are generally consistent variations between wind–wave climate and energy, both in magnitude and in seasonality. Based on these results, differentiated exploitation schemes considering the complementarity or synergy of wind and wave according to different seasons are recommended.

Offshore wind is nowadays already well developed in the North European countries. Ninety‐nine percent of the offshore wind turbines are installed on fixed foundations in shallow waters. For areas with water depth greater than 50–60 m, the floating wind is the cheapest and mostly used technology. This technology is going to reach the commercial phase in a few years, thus disclosing the potential of all marine areas with deep waters close to the coast, including the Mediterranean basin. One of the main challenges for floating offshore wind deployment in this area is the achievement of its economic feasibility. The offshore wind resource in the Mediterranean is generally lower than the one in the North Sea and in Oceans and the cost of offshore wind farms, especially with floating technology, is higher than the present offshore wind farm installations also because this industrial sector has not yet started in this area. However, in the Mediterranean area, the potential of offshore wind to contribute to the decarbonization pathway and reduce the dependence on imported fuel supply is substantial. Numerous studies, examined in this article, have already performed a technical‐economic assessment of offshore wind farms in different countries and geographical areas within the basin. A significant number of offshore wind projects are already in different stages of development, confirming the industrial interest and readiness of the Mediterranean offshore wind energy sector. The article provides a comprehensive review of various factors influencing the future deployment of offshore wind in the Mediterranean. It covers a range of topics including technology advancements, resource assessment, wind energy potential, ongoing projects, costs, and economic aspects. Additionally, it discusses environmental sustainability, regulatory frameworks, supply chain logistics, and system integration. The updated review presented in this article could assist decision‐makers and stakeholders in gaining a better understanding of the characteristics of this promising sector and accelerating its development.This article is categorized under: Sustainable Energy > Wind Energy
