A System Investigation of Tidal Stream Energy Resource in Singapore 

Climate change is accelerating the global demand for sustainable and renewable energy sources to mitigate its impacts and reduce greenhouse gas emissions. Among these, ocean tidal stream energy has attracted increasing attention for its potential to contribute significantly to the renewable energy mix while reducing emissions. In this study, we conduct a high-resolution (up to 50 m) numerical investigation of tidal stream energy extraction using the 3D hydrodynamic model FVCOM. The model's accuracy is validated using 15-day observational data from several tidal level and current stations. The spatial distribution and energy potential of tidal streams were analyzed to identify the most suitable areas for tidal stream energy development, with consideration given to energy potential, variability, and water depth. Additionally, a novel method was developed to quantify potential electricity production from tidal stream energy at the national scale. A quantitative evaluation of various Tidal Current Turbines (TCTs) was performed in the identified regions, factoring in both energy yield and power output stability. Results indicate that the southwestern region of Singapore demonstrates high potential for tidal stream energy development. The NNU-300 kW turbine, with a rated power of 300 kW and a rotor diameter of 17 meters, was found to be the most efficient in most areas.
