The invention discloses a safety hydrogen storage device of a hydrogen energy booster vehicle and a hydrogen supply system thereof. The safety hydrogen storage device comprises a hydrogen storage bottle and a valve arranged at the mouth of the hydrogen storage bottle. The hydrogen storage bottle sequentially comprises a inner container, a winding layer and an outer shell from inside to outside. The valve is a top-opening valve. The valve comprises a valve body, a top column, bulges, a spring, an air nozzle, an elastic pressurizing ring, a vent hole and a connecting groove. The valve body is ina cap shape and is suitable for being connected with a hydrogen cylinder, and a groove is arranged inside the valve body. The top column penetrates through the valve body and is suitable for moving up and down in the valve body. The upper part of the top column is provided with a circle of bulges, and the bulges are arranged in the grooves in the valve body. The spring is suitable for providing upward moving force for the top column. The air nozzle is matched with the bottom of the top column, and the top column is suitable for opening the air nozzle when moving downwards. The elastic pressurizing ring is arranged at the lower part of the air nozzle in a sleeving manner. The center of the top column is provided with the vent hole suitable for gas to pass through. The top of the valve bodyis provided with the connecting groove. According to the safety hydrogen storage device of the hydrogen energy booster vehicle and the hydrogen supply system thereof, by arranging a top-opening typevalve mechanism and a rebound and protection structure, the structure is simplified, and meanwhile, the safety is ensured; and a vertical z-shaped air nozzle is arranged, the sealing area of the air nozzle can be effectively increased, the sealing performance is improved, and the safety is further improved.
