The NH3CRAFT project represents a pioneering initiative aimed at revolutionizing maritime propulsion by developing a cutting-edge technology for the high-volume storage and transportation of ammonia as a sustainable onboard ship fuel. This research constitutes a pivotal component of the NH3CRAFT endeavour, focusing on the design, development, and demonstration of advanced ammonia storage systems within marine vessels. The primary objective of NH3CRAFT is to devise a commercially viable, safe, and high-capacity technology for ammonia storage and utilization as a maritime fuel. The project's focal point involves the design methodology for achieving the feasibility of storing 1,000 m3 of liquid ammonia at a pressure of 10 bar, exemplified by its demonstration on a 31,000-deadweight ton multi-purpose vessel. Furthermore, the project aims for broader applicability and refinement of the developed methodology by conducting comprehensive studies encompassing five different vessel types and corresponding fuel-storage tank concepts.
This research delves into the core elements of NH3CRAFT's innovative approach, emphasizing the development of composite fuel storage tanks tailored specifically for ammonia storage in marine applications. Specifically, investigation of diverse external geometries for ammonia storage tanks is carried out to maximize amount of stored fuel while adhering to international codes, rules, and regulations in the context of marine engineering. The methodology involves design space exploration, design optimization, structural analysis, and experimental validation to ensure the integrity, safety, and efficiency of the ammonia storage systems within the diverse and predefined operational contexts of various vessel types.
This study results into a detailed manufacturable design of composite pressure vessels, thereby significantly contributing to the NH3CRAFT project's goal of fostering sustainable maritime transportation through the adoption of ammonia as a clean, greenhouse gas-reducing fuel. By advancing the technology and feasibility of high-capacity ammonia storage on ships, this research paves the way for a new era of environmentally conscious and commercially viable marine propulsion systems.
