1. Jingcheng Co., Ltd. (600860), as a leading enterprise in the utilization of hydrogen energy in China, has a core advantage in the manufacture of hydrogen storage and transportation equipment. Last year, public funds were raised to build the production capacity of type IV hydrogen storage bottles. In the future, with the development of the industry and the improvement of production capacity, it is expected to usher in a period of rapid growth in performance.
2. According to public information, the main business of Beijing Jingcheng Electromechanical Co., Ltd. is the manufacture of gas storage and transportation equipment; The company's main products are liquefied natural gas (LNG) cylinders for vehicles, compressed natural gas (CNG) cylinders for vehicles, seamless cylinders, welded cylinders, welded insulation cylinders, carbon fiber fully wound composite cylinders, perforated acetylene cylinders without asbestos filler, ISO tank containers, aluminum-carbon fiber fully wound composite cylinders for hydrogen fuel cells, low-temperature storage tanks and LNG filling station equipment. The transportation cost is mainly related to the storage and transportation of hydrogen. In this regard, the IV hydrogen storage bottle widely used in the international market has been in a blank state in China for a long time.
3. Generally, there are four kinds of hydrogen storage bottles: Type I bottles are all made of steel, the main disadvantage is that they are relatively heavy, so they are not suitable for vehicles, and can be placed in hydrogen filling stations as fixed hydrogen storage; Type _ and _ bottles are wrapped with metal-lined carbon fiber, which is relatively heavy, but lighter than Type _ bottles. Type _ bottle is a plastic liner wrapped with carbon fiber, which is the lightest and suitable for vehicles. It is the mainstream technical route abroad. In fact, the research and application of Class IV compressed natural gas cylinders have been carried out in China. However, due to the immature initial design, manufacturing and testing technology, the product has certain defects, leading to safety accidents, and it is still banned from use. At present, the national IV hydrogen storage bottle is still a "bottleneck" problem in the domestic hydrogen energy industry.
