Adaptability evaluation of wind-solar-hydrogen-energy storage in port-ship multi-energy integration system based on AHP-TOPSIS

Abstract

Shipping industry is the lifeline that responsible for 80% of the total global trade. At the same time, environmental pollution and greenhouse gas emissions caused by the port and shipping industry have become the focus of attention of the international community. In order to promote green, low-carbon and sustainable development of waterway transportation, a port-ship multi-energy integration system has been constructed by using three renewable energy including wind power, solar energy, hydrogen, and one energy storage technique. Taking China as an example, this paper analyzes the adaptability of 4 ways of energy supply in the design of multi-energy integration system of port-ship theoretically and then the AHPTOPSIS method is adopted to evaluate their adaptability from policy and standard support, technological development, energy availability, economic efficiency, and environmental friendliness perspectives. The methodology of this paper can be extensively employed on performance evaluation of multi-energy integration system from national or port level.
