Abstract

In marine applications, the energy storage system (ESS) functions as the primary energy supply for fully electric propulsion vessels. During variable operation conditions involving pulsed propulsion load, the ESS employing monotype topologies are often oversized and can damage the cells. This study proposes a hybrid energy storage system (HESS) for an all-electric Seabus with a 10-year operational lifespan, with the objective of optimizing the storage system size to ensure longer operation than 72 minutes at a speed of 30 knots under variable conditions. The impact of the HESS system on installation cost and weight was thoroughly investigated. Some HESS configurations are presented, utilizing Lithium Iron Phosphate (LFP) as the high-energy (HE) cell and supercapacitors, Lithium Ion Capacitor (LIC), and Lithium Titanium Oxide (LTO) as three alternatives of the high-power (HP) cell. The HESS design predates a parallel full-active configuration with a rule-based energy management method that utilizes cut-off power between HE and HP cells. In this specific case, the LFP-LTO configuration is the optimal HESS design rather than the LFP-SC and LFP-LIC configurations, meeting all established optimization criteria and weight limitations. The study demonstrates that the HESS configuration can achieve 120 minutes of operation, which is 67% longer than the operation time of previous Seabus operations.

Abstract

As the marine industry now is running toward the green and more efficient propulsion system, the optimization has also become a primary part of the research. This research study is focusing on the optimal sizing of Hybrid Energy Storage (HESS) in electric ship using Multi-Objective Genetic Algorithm (MOGA). By integrating the battery and supercapacitor (SC), it helps cover the load demand while enhancing a good performance to the ship. This research study is to optimize sizing of HESS with a suitable Energy management System (EMS) to desired the intention of minimize the total cost of HESS and degradation of the battery. The proposed model addresses the complexity of HESS while optimized the distribution of power for both the battery and SC, handling the load condition.

Abstract

The fossil fuel emissions from the ship have significant impacts on climate change, environmental quality, and human health. The marine sector has consequently grown increasingly interested in implementing greener and more sustainable energy solutions. The electric propulsion ship is powered by hybrid energy storage has the ability to lower emissions, improve the power quality, and lower fuel consumption. There are many types of energy storage system such as battery, supercapacitor, hydrogen, etc. In this study, the combine of battery and supercapacitor are chosen as a hybrid energy storage system to supply power to the electric ship and diesel generator is an additional power source. The main objective is to sizing the hybrid energy storage system to minimize the total cost while maintaining reliable energy supply. The optimal sizing of each component is conducted in MATLAB using Genetic Algorithm. The result indicates that the optimal power rated of Pbat is 100 kW and Psc is 301.19 kW, while the optimal capacities rated of Ebat is 121.27 kWh and Esc is 109.86 kWh. Over a 20-year period, the total of this project is $1,390,422.

Abstract

Risk assessment of Energy Storage Systems (ESS) in ships is a fundamental requirement to ensure operational safety in the maritime sector. This study investigates risk analysis and mitigation strategies for a Hybrid Energy Storage System (HESS) applied to a 11-meter fully-electric Seabus, configured with Lithium Iron Phosphate (LFP) and Lithium Titanate Oxide (LTO). The Hazard Identification (HAZID) method is employed to systematically identify potential hazards during operation, covering technical, operational, and environmental aspects. The findings reveal that hazards with the highest risk ranking include explosion and battery fire, both of which pose severe threats to vessel safety and environmental integrity. To address these critical risks, appropriate mitigation strategies are proposed, including advanced battery management systems, physical protection of critical components, and emergency operational procedures tailored to maritime safety standards. This research highlights the importance of integrating HAZID into the design and operation of HESS to enhance reliability and safety
