601525 lipo batteryThe realization of hydrogen energy commercialization focuses on breaking through technical bottlenecks

　　Not long ago, the car in Nanyang, Henan that "can run with water" ignited the topic of hydrogen energy vehicles and even the hydrogen energy industry. On the 12th, the first international hydrogen energy standards and safety high-end forum was held in Nanhai District, Foshan City, Guangdong Province. How to develop the hydrogen energy industry has become the focus of experts. Experts attending the meeting pointed out that hydrogen energy will become an important strategic choice for optimizing the energy structure, both in China and the world. At present, we should vigorously break through the bottlenecks of hydrogen refueling stations and hydrogen production facilities, increase planning, construction and support, and promote implementation in a practical manner without using gimmicks or deception. After the meeting, Chen Linxin, senior adviser to the National Hydrogen Energy Standards Technical Committee, said in an interview with a reporter from Science and Technology Daily that the development of my country's hydrogen energy industry is still in the transition period from "demonstration" to "commercial use" and has not yet reached the explosive period. The key to how long the transition period will be depends on whether the hydrogen energy industry can develop healthily. "Japan has been promoting hydrogen energy for so many years, but it has not yet achieved commercial operation. It can be seen that the commercialization of hydrogen energy in my country still takes time." Chen Linxin said that the commercialization of hydrogen energy requires solving the source of hydrogen production, improving the public's correct understanding of hydrogen energy, and Break through the "stuck neck" technical problems in all aspects of the hydrogen energy industry chain. According to incomplete statistics, there are currently more than 200 hydrogen energy standards worldwide. "Standards are an important technical support for the application and promotion of hydrogen energy technology. The hydrogen energy industry is developing rapidly, changing rapidly, updating rapidly, and has high technical content. In order to adapt to and meet the development needs of the hydrogen energy industry, the development of standards and specifications should go hand in hand with technological development. ." said Andrei V. Tchouvelev, Chairman of the International Organization for Standardization's Hydrogen Energy Technical Committee. He pointed out that the development of the hydrogen energy industry must make it clear that hydrogen is an energy carrier. Although hydrogen is a hazardous chemical, it is also an energy carrier. It should be regulated like natural gas and fuel oil. This is the policy and regulation for the hydrogen energy industry. , an important basis for regulating the market, etc. And many years of application practice at home and abroad have proven that as long as hydrogen energy is produced, stored and used in accordance with standard specifications and regulations, the safety of hydrogen energy can be guaranteed. In Chen Linxin’s view, if my country wants to further develop the hydrogen energy industry, it needs to break through the key technologies in each link of the hydrogen energy industry chain. The most urgent of these is the lack of liquid hydrogen equipment manufacturing and processing technology, and how to achieve the required large quantities of liquid hydrogen after commercialization. Long-distance gas and hydrogen pipeline transportation. Because "hydrogen energy infrastructure is not only the construction of hydrogen refueling stations, but also hydrogen production and storage and transportation technologies." "Only with low carbon and low cost can hydrogen become a veritable green secondary energy." Chen Linxin believes that hydrogen energy terminals Only when the carbon emissions and cost price of hydrogen consumption at the place of use are lower than the carbon emissions and cost price of the same fossil fuels such as fuel oil, or are of a considerable "magnitude", can it be called a "low-carbon and low-cost hydrogen source." At present, my country's hydrogen energy vehicle development goals are to reach 5,000 vehicles in 2020, 50,000 vehicles in 2025, and one million vehicles in 2030. "The low-carbon and low-cost hydrogen source for hydrogen vehicles should include the carbon emissions and cost price of the entire process from hydrogen production to hydrogenation guns." He suggested that in areas where resource conditions permit, priority should be given to the development of renewable energy hydrogen production. , in the agglomeration areas of wind power, hydropower, and photovoltaic power generation, large-scale water electrolysis hydrogen production is planned and constructed, and pipeline transportation or liquid hydrogen is used to transport it to the place of use.
