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 WEC sub-system is self-adaptable to different wave heights, tidal ranges, and incident wave directions. Following UoP, DLUT [60,61] also put forward the proposal of W-OWC device and optimized the shaped and chamber of the OWC, as shown in figure 8. The other design is an internal OWC, which opens several holes underwater and utilizes the monopile as the air chamber.…”

“…Besides, there are some in-house codes, like Aquaplus based on boundary element method (BEM) for calculating the hydrodynamic coefficients of C-HyP. DLUT [60,61] investigated the coupled hydrodynamic response of a cylindrical-type OWC device by a 3D time-domain NUM model based on the higher-order BEM. The key point of the simulation is the dynamic coupling of WTs and WECs.…”

The urgent demand for energy structural reform and the limitations of single energy development have promoted the combination of wind energy and wave energy. A hybrid energy system means that two or more energy devices share the same foundation. It reduces the levelized cost of energy (LCOE) and improves competitiveness through infrastructure sharing and increased power output. This paper starts with the development of the joint resources of wind and wave energies, then introduces the foundation forms of the hybrid system. It reviews the latest concepts and devices proposed with the integration of wind energy and wave energy, according to the foundation forms, and makes a preliminary assessment of the synergies of the hybrid system. The existing study methods of the hybrid systems are summarized. In view of the challenges faced by the development of hybrid energy systems, several suggestions are put forward accordingly. This paper provides a comprehensive guideline for the future development of the hybrid wind-wave energy converter (W-WEC) system.

“…As a result, the design of hybrid technologies should be the next stage in the growth of the ocean renewable industry [15]. Hybrid developments integrate floating wind turbines with WECs to harvest energy from the A novel integrated approach for the multi-application usage of offshore renewable energy resources that consists of an OWC device and an offshore wind turbine is developed in [45]. A monopile structure supports the wind turbine, and the associated OWC is concentric with the structure.…”
