Sammendrag
The maritime industry faces growing demands to reduce greenhouse gas emissions and operational costs while maintaining reliability and efficiency. This thesis explores the potential of Hybrid Power Systems (HPS) to meet these challenges, focusing on the integration of renewable energy sources, energy storage systems (ESS), and cold ironing (CI) facilities. Using a case study of a vessel operating between Stockholm and Mariehamn, this research investigates how innovative energy solutions can transform maritime operations into more sustainable and cost-effective systems.
The study begins by analyzing the energy requirements of the vessel, including propulsion and service loads, and identifies the limitations of conventional diesel-powered systems. A hybrid energy system is designed, combining solar photovoltaic (PV) panels for daytime energy generation, an Energy Storage System (ESS) for energy storage and load balancing, and Cold Ironing (CI) facilities to provide emission-free power during berthing. The thesis evaluates these systems' technical and economic performance across different operational scenarios by applying mathematical models and running detailed simulations.
Key findings reveal that integrating hybrid power systems significantly reduces fuel dependency and greenhouse gas emissions. Photovoltaic (PV) panels efficiently generate energy during daylight hours, while the Energy Storage System (ESS) stores additional energy during peak demand. Cold ironing facilities eliminate emissions during port stays, enabling vessels to comply with stringent environmental regulations. The optimized hybrid configuration proposed in this thesis achieves up to 40% reductions in operational costs and emissions compared to traditional diesel-only systems, demonstrating its feasibility and long-term benefits.
This research provides valuable insights for ship operators, port authorities, and policymakers seeking to modernize the maritime sector. By showcasing the adaptability of hybrid power systems to various vessel types and routes, the study offers a practical framework for reducing environmental impact without compromising operational efficiency. For anyone interested in sustainable shipping solutions, this thesis delivers a compelling case for adopting hybrid energy systems as a cornerstone of the industry’s future.
