Enhancing Submarine Propulsion: Hydrogen SI Engine With EGR for NOx Reduction Monitored by AI.

This research paper underscores the critical importance of advancing submarine technology by proposing a fully hydrogen‐powered submarine integrated with an air‐independent propulsion (AIP) system and artificial intelligence (AI)‐driven safety measures. Such an innovative approach not only addresses the limitations of traditional diesel‐electric submarines but also promises to revolutionize naval operations. The adoption of hydrogen as the primary power source significantly extends the submarine's operational range, reducing its dependence on fossil fuels and minimizing environmental impact. The incorporation of AIP technology enables sustained underwater endurance, reducing vulnerability and enhancing mission effectiveness. Concurrently, AI‐driven safety measures provide robust leak detection and safe hydrogen handling, ensuring the well‐being of the crew while optimizing operational efficiency. This integrated solution represents a transformative step toward achieving a more sustainable, capable, and stealthy submarine fleet for modern warfare scenarios. [ABSTRACT FROM AUTHOR]
