Special Issue Information

Dear Colleagues,

The transition to renewable energy is critical to addressing climate change and meeting global energy needs. Wind, tidal, and wave power are emerging as key players in this transformation, offering sustainable solutions to harness the vast potential of marine and offshore resources. However, their development is challenged by technical, environmental, and economic factors, requiring innovative research and interdisciplinary approaches.

This Special Issue aims to highlight advancements in wind, tidal, and wave energy technologies by addressing key topics such as resource assessments, opportunities and challenges in technology development, numerical modeling and simulations of renewable energy devices, design load definitions for marine and offshore structures, control strategies, and grid integration. Additionally, this Special Issue will explore methods for evaluating and managing the risks and uncertainties in marine and offshore renewable energy systems.

Contributions should focus on improving the reliability, efficiency, and sustainability of these energy systems while addressing the complexities of operating in dynamic and challenging offshore environments.

This study presents a pulley-buoy-accelerated linear wave power generation system and verifies its feasibility and effectiveness through experimental research. Compared with traditional wave power generation systems that rely on three-stage energy conversion, the proposed system eliminates intermediate energy transfer and conversion links, enabling direct extraction of electrical energy from wave-induced motion. Additionally, by incorporating a pulley assembly, the system amplifies the buoy’s motion speed. This enhancement boosts the power output of the linear generator and improves the system’s overall wave energy conversion efficiency. Under laboratory conditions, a small-scale prototype of the system and a swing-type wave generator were constructed. Experimental tests were conducted to examine how three key factors influence the system’s power generation performance: the number of stator coils, wave conditions (wave height and wavelength), and buoy size. The results indicate that three measures can effectively improve both the wave energy conversion efficiency and power generation performance of the pulley-buoy-accelerated system: increasing the number of stator coils, increasing wave height and wavelength, and moderately enlarging the buoy size. These findings offer valuable insights for the practical application and efficient operation of wave power generation systems. Full article
