A study on applicability of Battery Energy Storage System (BESS) for electric propulsion ships

The electric propulsion ship has been considered an alternative for stricter environmental regulations and safety issues. As electric propulsion ships have been developed, the attention given to a Battery Energy Storage System (BESS) has also grown for green and efficient power supply. However, a BESS-installed ship is still regarded as a non-preferred power source in terms of reliability and cost-competitiveness. In this regard, this paper shows the possibility of a BESS-installed ship. Two major drawbacks of applying the BESS as a ship's power source are mentioned, and possible solutions are suggested and reviewed. These introduced solutions could contribute extending the applicability of a BESS and boosting its realistic utilization in the marine industry.
