Two brand-new hydrogen energy heavy truck test vehicles slowly drive in and stop at both sides of the hydrogenation machine. The staff wearing anti-static work clothes and safety helmet shall pull out the gas gun and put it into the vehicle filler after the triangular wooden plug of the stable vehicle is placed in the standard. With the "hiss" sound of intake air, the number on the hydrogenation machine jumps and the filling amount is displayed in real time. Not long ago, at Pengfei BeiYao hydrogen charging comprehensive energy station in Xiaoyi City, Luliang, Shanxi Province, the hydrogen energy heavy truck made a "smart" appearance after successfully completing hydrogen filling. Hydrogen energy is gradually maturing in Shanxi, the energy base. Entering Shanxi Meijin Huasheng new chemical materials Co., Ltd., large hydrogen fuel cell heavy trucks and large buses shuttle through the clean plant area. The intelligent terminal control operation system makes people mistakenly think that they have entered a science and technology enterprise. It is reported that Meijin energy has a complete industrial chain integrating "coal coke gas chemical hydrogen". Around the hydrogen energy industry chain, Shanxi has made a key layout. Previously, Shanxi Province issued the medium and long term plan for the development of hydrogen energy industry in Shanxi Province (2022-2035), focusing on the key links of "production, storage, transportation, addition and use" in the development of hydrogen energy industry, to study and formulate the management measures for the construction and operation of hydrogen stations, improve the hydrogen energy industry standard system, strengthen the hydrogen energy safety management and the whole industry safety standards. "Most of the hydrogen in China mainly comes from coal - a large amount of hydrogen will be produced in the process of coal coking. As a big coal province, Shanxi has a natural advantage in the cost of hydrogen production." According to the relevant person in charge of Shanxi Provincial Department of industry and information technology, Shanxi is rich in hydrogen resources. The byproduct of coke production, coke oven gas, contains about 60% hydrogen, and can extract 14 billion cubic meters of hydrogen annually. The cost of producing hydrogen from coke oven gas is low and the application prospect is broad. (news agency)
