Recent research published in ‘Heliyon’ explores a promising approach for enhancing the efficiency of DP-2 vessels through the integration of Battery Energy Storage Systems (BESS). Led by Sankarshan Durgaprasad from Delft University of Technology, this study introduces a framework called Battery Optimization for Optimal Sizing and Throughput Energy Regulation (BOOSTER). This framework aims to optimize battery size, technology selection, and power generation scheduling while also factoring in battery degradation.
The research focuses on a detailed analysis of twelve different battery sizes, assessing their performance based on three critical metrics: return on investment, payback period, and years of profitability. This is particularly relevant for the maritime industry, where operational efficiency and cost savings are paramount. To achieve this, the study employs a Mixed Integer Linear Programming (MILP) model to manage the energy and power systems of the vessel, ensuring both fuel and economic efficiency.
Durgaprasad’s team examined two distinct load profiles for DP-2 vessels operating in regions near Taiwan and the North Sea. One of the significant findings from the study is the importance of considering battery ownership costs, specifically in terms of energy throughput costs and fuel prices. This approach can lead to a longer battery lifespan and a higher return on investment, which is crucial for vessel operators looking to enhance their bottom line.
The research also introduces a BESS operation matrix, which serves as a practical tool for vessel operators. This matrix provides insights into how BESS can be utilized for economic benefits, translating complex analytics into actionable strategies that can be implemented in real-time operations. “Our findings emphasize the significance of taking battery ownership costs into account, resulting in a longer battery lifetime and higher return on investment,” said Durgaprasad.
The implications of this research extend beyond individual vessels. As the maritime sector increasingly seeks sustainable solutions, the integration of BESS can play a vital role in reducing fuel consumption and emissions. This not only aligns with global environmental goals but also presents commercial opportunities for companies involved in battery technology, energy management systems, and maritime operations.
In summary, this study highlights a pathway for DP-2 vessels to optimize their energy systems, potentially leading to significant cost savings and enhanced operational efficiency. As the industry moves toward more sustainable practices, the insights from Durgaprasad and his colleagues could be instrumental in shaping the future of maritime energy management.
