Assessment of onshore power supply for ship’s emissions reduction in Alexandria Port utilizing national grad/ renewable energy.

ABSTRACT Air pollution from shipping is a critical issue, especially in dense ports. One of the proposed technologies to reduce ship emissions in ports is the Onshore Power Supply (OPS) system, where ships turn off their auxiliary electric generator engines and connect into the port grid. Several studies were conducted in European and USA ports. This study tackles the application of the OPS in the port of Alexandria, in line with Egypt’s Vision 2030 concerning the issue of climate change. The study focuses on analyzing the ships data collected from Alexandria port along one month. The present investigation aiming to conduct a comprehensive socio-economic and cost effectiveness analyses of OPS. To enhance the environmental potential of OPS, deploying four solar energy scenarios as the OPS electricity source is proposed. The results revealed that relying on the national grid decreases emissions by 27.5%, and it is predicted to reach 100% if the electricity is generated from solar energy. Also, the economic analysis shows good profitability with a payback period of almost two years. Therefore, the implementation of the solar-powered OPS system in Alexandria port not only contributes to improving the air quality in the area, but also enhancing the country’s environmental, social and economic goals. Improving port infrastructure and using clean energy technologies can significantly enhance the quality of life in port cities and promote sustainable development.
