Research on Hydrogenation Process Performance of High Pressure Hydrogen Storage Tank on Passenger Ship

Abstract

In an environment where the international community vigorously advocates “clean energy” and “new energy green ships”, the US new energy high-speed passenger ferry “SF-BREEZE” is used as the object, and COMSOL simulation software is used to build the hydrogen storage tank model of the ship. In the simulation experiment under the conditions, the influence of the charging flow rate on the main hydrogen storage performance during the hydrogen filling process of the ship hydrogen storage tank was studied, and the influence of the charging flow rate on the main performance of the hydrogen storage tank was obtained. The simulation results show that the change of the mass flow rate at the hydrogen injection port will cause significant changes in the temperature, SOC, and pressure in the hydrogen storage tank. When the mass flow rate increases, the two-dimensional average temperature in the hydrogen storage tank and the temperature of each detection point show an upward trend, and when the same filling quality is met, the variable inlet mass flow rate used in this experiment is Compared with the constant mass flow at the inlet, the range of temperature rise is smaller. During the filling process, the mass flow curve has a large value in the earl and mid-term, and gradually decreases in the middle and late periods to obtain better hydrogen storage performance. Within the safety standard range of the ship's hydrogen charging temperature of 358K, the average mass flow can be maximized during the hydrogen charging process to obtain a higher SOC value.
