Assessing the wind energy potential of Hai Phong’s offshore area

Abstract

While offshore wind farms are a global reality, Vietnam remains untapped in this renewable energy sector. Hai Phong, a city experiencing rapid economic growth, faces increasing electricity demands. This study assessed the wind energy potential of Hai Phong’s offshore area by calculating wind energy density at 10 meters and extrapolating to 100 meters using meteorological data and semi-empirical formulas. Results indicate significantly higher average wind energy density offshore compared to coastal areas (1.36 times at 10 meters). At 100 meters, average wind energy density fluctuates substantially (2,927 to 22,108 W/m²) with a notable difference between monsoon seasons (2.04 times higher in the Southwest monsoon than the Northeast one). This preliminary investigation seeks to evaluate the potential of Hai Phong’s sea wind as a resource, laying the groundwork for comprehensive research initiatives in the future.
