[0002] In response to the impacts of climate change, the shipping industry is facing increasing pressure from new regulations from the International Maritime Organization (IMO). Ammonia fuel produces nitrogen and water after combustion, and its carbon reduction capacity reaches 100%, making it an ideal zero-carbon fuel with the greatest development potential in the shipping industry.

[0003] However, ammonia is currently a "high-risk" alternative fuel. In the event of a ship running aground, a fuel tank rupture, or an ammonia leak, the risk is extremely high. This is exactly the problem with ammonia fuel power solutions in terms of safe storage, stable supply, inerting and explosion prevention, emergency discharge, and leakage recovery on ships. The role of the ammonia fuel transmission system controller in the ammonia fuel transmission system is particularly critical, determining the safety and stability of the entire system. However, testing the controller based entirely on the actual ammonia fuel transmission system is dangerous, the facilities occupy a large area, and the capital and time costs are high.
