AI Technical Summary
Existing ammonia-hydrogen engine systems have low hydrogen production efficiency when exhaust gas temperature fluctuates greatly, rely on precious metal catalysts and have high energy consumption, and the separation of exhaust gas treatment devices from heat storage systems leads to insufficient catalyst activity during cold starts, increasing system complexity and cost.
By employing molten salt thermal storage technology, waste heat from exhaust gas is stored and molten salt is circulated to provide a heat source for the thermal decomposition reaction of ammonia. This integrates exhaust gas treatment and thermal storage systems, and utilizes inexpensive catalysts to achieve ammonia decomposition under a stable heat source, forming an energy closed loop.
It enables the rapid supply of heat required for hydrogen production from ammonia reforming in a short period of time, improves hydrogen production efficiency, reduces dependence on precious metal catalysts, simplifies system structure, and enhances energy utilization efficiency and combustion stability.
