Abstract:

Economic growth increases energy demand while fossil fuel resources are gradually being depleted and contribute to climate change. Therefore, the development of renewable energy sources is essential. Ocean wave energy, with an estimated global potential of about 1 TW, is abundant and environmentally friendly. Vietnam has significant advantages in this resource; however, studies on assessing wave power density (Pw) using satellite altimetry data remain limited. The paper focuses on calculating wave power density based on wave heights derived from satellite altimetry data over the East Sea. Various formulas for computing wave power density are reviewed, compared, and validated. The study also examines the influence of water depth and gravity on Pw. A cross-validation-based approach is developed to evaluate Pw, from which a computational workflow is established. To automate Pw calculations, the authors develop and verify a computer program. An experiment is conducted in the East Sea using SARAL/AltiKa satellite data from cycle 32, collected between 03 March 2016 and 06 April 2016, comprising 7,542 measurement points. Results show that wave power density during the study period mainly ranges from 1.5 kW/m to 44.3 kW/m, with a Pw estimation error of ±1.023 kW/m. The study provides a foundation for comprehensive assessment of wave energy potential in the East Sea using satellite altimetry data.
