Renewable energy storage and sustainable design of hybrid energy powered ships: A case study

With rapidly increasing consumption of energy, shipping industry has imposed a huge burden on the marine environment. It is a general trend to increase the use of renewable energy on ships to improve the ship sustainability. This article summarized the current development and application of solar energy, wind energy and fuel cell in ship power systems. Furthermore, in order to investigate the advantages of sustainable design for the ships, for the first time, a hybrid PV, wind and fuel cell energy system was established for an oil tanker, and the economic and environmental analyses of the hybrid system were performed. The analysis results demonstrate that the optimal hybrid energy system can reduce 151,467kg emission of CO2 and provide 2.92% electricity for the ship gird per year.

Automated summary

The shipping industry's increasing energy consumption has put a huge burden on the marine environment. The trend to increase the use of renewable energy on ships for sustainability is evident. Research shows that a hybrid energy system utilizing solar, wind, and fuel cell technologies can significantly reduce emissions and provide electricity for ships.
