With the continuous growth in global energy demand, the limitations in supply and market volatility of traditional fossil fuels (oil, coal, and natural gas) have become increasingly prominent. Furthermore, the dual pressures of economic development and climate change have sparked widespread attention toward sustainable energy solutions. Against this backdrop, marine energy has emerged as a promising renewable resource, attracting significant interest. The vast energy potential of waves, tides, offshore currents, and swells offers new opportunities to address the global energy crisis and promote green development.
