LCA Impact Cost of Ownership of B2G on Power Electronics and Battery
(2025) MVKM05 20251Department of Energy Sciences
- Abstract
- This thesis explores the long-term viability of integrating Boat-to-Grid (B2G) systems into electric marine vessels, considering technical reliability, environmental impact, and economic feasibility. Through degradation modeling, simulation-based analysis, lifecycle assessment, and financial modeling within the context of Göteborg, Sweden, this work offers a framework to understand how electric boats can contribute to grid flexibility while maintaining operational and financial sustainability. The study assesses the performance of Dual Active Bridge (DAB) converters and Neutral Point Clamped (NPC) inverters, evaluates the degradation of Nickel-Cobalt-Aluminium (NCA) batteries under B2G cycling, and examines the economic potential of grid...

The study assesses the performance of Dual Active Bridge (DAB) converters and Neutral Point Clamped (NPC) inverters, evaluates the degradation of Nickel-Cobalt-Aluminium (NCA) batteries under B2G cycling, and examines the economic potential of grid interaction, considering local energy and tax policies. The results highlight the importance of smart operational strategies and power management to ensure the economic and environmental benefits of B2G systems in electric boats. (Less)
- Popular Abstract
- Lithium-ion batteries (LIBs), particularly Nickel-Cobalt-Aluminum (NCA) variants, are widely recognized as essential technologies for applications such as electric vehicles, renewable energy storage, and portable electronics. The superior energy density, extended lifespan, and thermal stability of NCA batteries make them a preferred choice for demanding applications, including electric marine propulsion. This study examines
the performance, lifespan, environmental impact, and economic feasibility of NCA batteries in electric boats. It analyzes how operational patterns, such as charge-discharge cycles and power management, affect battery degradation. The findings show that optimized charging strategies can significantly extend battery...

The superior energy density, extended lifespan, and thermal stability of NCA batteries make them a preferred choice for demanding applications, including electric marine propulsion. This study examines
the performance, lifespan, environmental impact, and economic feasibility of NCA batteries in electric boats. It analyzes how operational patterns, such as charge-discharge cycles and power management, affect battery degradation. The findings show that optimized charging strategies can significantly extend battery life. Additionally, the economic analysis considers the profitability of integrating batteries with the electrical grid, taking into account fluctuating electricity prices and decreasing battery costs. The results suggest that NCA batteries present a sustainable and economically viable solution for cleaner maritime transportation. (Less)
