Since the beginning of this year, more than 50 cities in China have released hydrogen energy industry plans, and the top-level design for hydrogen energy development at the national level is also coming out soon.
From the perspective of the industrial chain, the on-board hydrogen storage system has become an important breakthrough for the large-scale commercial use of hydrogen vehicles. At present, in the high-pressure gaseous hydrogen storage system used in mass-produced hydrogen vehicles, tank materials and carbon fiber raw materials have been domestically produced, but the bottle mouth valve of the high-pressure hydrogen storage bottle has become the "core bottleneck" link. The market is mainly composed of Canadian GFI, Companies such as OMB in Italy and Luxfer in the United States occupy a small number of Chinese companies, such as SHSH.
As a key component of the high-pressure hydrogen storage bottle, the mouth valve of the high-pressure hydrogen storage bottle has a highly concentrated function, including step-down and stabilization (the pressure in the hydrogen storage bottle is 35Mpa/70Mpa, and the normal working pressure of the fuel cell is less than 1Mpa), and high-reliability sealing (hydrogen molecule Small extremely easy to escape), real-time monitoring of temperature and pressure (cylinder safety guarantee), rapid hydrogenation (fill two 50L bottles within 5 minutes), automatic manual pressure relief (safety protection). At the same time, the valve itself also needs to avoid hydrogen corrosion and hydrogen embrittlement of the metal, and the technical difficulty is further increased.
The industry predicts that from 2021 to 2025, the average annual growth rate of the domestic new market demand for vehicle-mounted hydrogen storage bottles will reach 78%, and China will become the world's largest vehicle-mounted hydrogen storage bottle market.
With the upgrade of high-pressure hydrogen storage bottle enterprise products represented by BJJC Hydrogen Energy Technology Corporation from Type III 35MPa to Type IV 70MPa and the future development of low-temperature liquid hydrogen storage, bottle mouth valve technology has become a "key" field that needs continuous breakthroughs. SHSH Industry leaders will usher in opportunities.
The 35MPa vehicle-mounted hydrogen cylinder valve and tail valve developed by SHSH successfully passed the type test of Dalian Boiler and Pressure Vessel Inspection and Testing Institute in China in March this year, making it the first in China.
In April 2021, SHSH became the first manufacturer in China to be certified by the German Ministry of Transport (KBA) for automotive hydrogen cylinder combination valves.
