Outline of Research at the Start

Among the renewable energies and ocean resources, wave energy has been less investigated due to high Levelized Cost of Energy (LCOE) associated with uncertainties in energy production estimations. However, development in the extraction technology is fast and the efficiency and suitability of wave energy exploitation depend on the areas where the technology is deployed, and it affects the estimated LCOE. Recent achievements in wave energy studies show that considering factors such as short-term variations and long-term changes are important in locating suitable sites with higher efficiency.
