AI Technical Summary
Existing solid hydrogen storage tanks consume a lot of energy during the hydrogen release process of magnesium-based solid hydrogen storage materials, mainly relying on electric heating, which leads to high energy consumption.
The exhaust gas from the internal combustion engine is used as the heating gas. The solid hydrogen storage material is heated through a heating tube. The high temperature of the exhaust gas is used to reduce energy consumption. The exhaust gas flow is regulated by a three-way control device to control the heating temperature and hydrogen production rate.
It effectively reduces the heating energy consumption of magnesium-based solid hydrogen storage materials, improves the utilization rate of exhaust gas, avoids energy waste, and enhances the system's operational reliability and the control precision of hydrogen production.
