| Abstract Scope |
To address the pressing need for sustainable, high-energy power solutions in maritime shipping, this work presents the design and feasibility analysis of a molten salt magnesium-air battery. Leveraging magnesium’s high energy density, abundance, and safety profile, the system uses a eutectic salt mixture to reduce melting temperature and support long-duration operation. A modular, 20-foot-container-scale battery was developed through CAD modeling and thermodynamic analysis to evaluate materials behavior, phase stability, and system integration. Experimental testing focused on electrode optimization and salt processing, achieving a maximum open-circuit voltage of 1.9 V. Cost modeling indicates competitive operational costs of $0.061/kWh, although capital costs remain a challenge. This work integrates theory, materials development, and system-level modeling to evaluate magnesium-air batteries as viable alternatives to fossil fuels for long-haul shipping. Ongoing efforts focus on scalability, recharge strategies, and modular deployment, contributing to the advancement of sustainable, application-driven energy materials that align with global decarbonization targets. |
