Background and Context Interest in harnessing wave and tidal energy began in the late 19th century and gained momentum through experimental prototypes in the 20th century. Modern advancements in marine renewable energy converters have responded to growing concerns over climate change and energy security. Early deployments raised environmental concerns about their potential impacts on marine habitats, including noise pollution, electromagnetic fields, and interactions with marine life such as collisions and entanglement. Biofouling, the accumulation of marine organisms on surfaces, emerged as a significant challenge for tidal stream turbines (TSTs), affecting their efficiency and longevity. Research focused on developing effective biofouling management strategies. Recent decades have seen rapid progress in monitoring biofouling, from traditional methods like visual inspections and hydroacoustic imaging to advanced techniques such as machine learning-based image processing and hyperspectral imaging. These innovations aim to provide real-time assessment and improve maintenance practices. Globally, countries like the United States, Scotland, and the United Kingdom have led in environmental impact assessments and regulatory frameworks for marine renewable energy projects, emphasizing adaptive management and sustainability in energy development. Continued research and collaboration are crucial to enhancing the sustainability and efficiency of marine renewable energy technologies as part of the global transition to a low-carbon future. |
