Review and Design of a Wave Energy Conversion System

The increasing demand for sustainable energy solutions has driven interest in harnessing ocean wave energy as a viable and renewable source of power. This project, titled "Review and Design of a Wave Energy Conversion System," aims to assess the wave energy potential along the Chilean coastline and design an efficient conversion system. The primary objectives are to quantify the power of waves at various coastal sites and evaluate the performance of advanced wave energy conversion technologies to maximize energy output and financial feasibility. The methodology involves data collection through oceanographic surveys and experimental analysis. Data was gathered using the R/V Kay Kay from the Universidad de Concepcin, which followed a predefined path along the coast to collect current profiles and conductivity-temperaturedepth (CTD) casts. Additionally, wave tank experiments at the Universidad Austral de Chile (UACh) provided damping coefficient measurements, which were compared with results from the Boundary Element Method (BEM) code WAMIT. Analytical models and numerical simulations were employed to calculate wave energy flux, density, and power available to conversion devices. Key results demonstrate that the Chilean coastline, with its unique meteorological and oceanographic conditions, offers significant wave energy potential. The analysis revealed that point absorber systems with optimized damping mechanisms achieved high efficiency in converting mechanical energy to electrical power. Furthermore, economic and environmental assessments indicated that integrating wave energy into the existing power grid could reduce dependency on fossil fuels and mitigate greenhouse gas emissions. In conclusion, this project provides a comprehensive evaluation of wave energy technologies and their application in Chile. The findings highlight the feasibility and benefits of wave energy conversion while addressing technical, financial, and environmental challenges. Future work will focus on refining the design and exploring advanced materials to enhance system durability and efficiency. The studys outcomes contribute to the global effort to develop sustainable and renewable energy solutions.
