A reporter from China Business News found that water-based hydrogen production technology is not new in developed countries such as Europe and the United States. It is still in the laboratory today.

　　Faced with doubts from across the country, 61-year-old Pang Qingnian, the leader of Young Auto, finally spoke.

　　"'Vehicle hydrolysis hydrogen production technology' requires the use of aluminum powder and water." Two days after the "water hydrogen production" story fermented, Pang Qingnian told the China Business News 1℃ reporter on May 25 that it also needs to be added. A "mysterious" catalyst composed of nanomaterials. After the incident, on May 24, 1℃ reporters disclosed the authoritative basic principles of this technology to the public for the first time (for details, see China Business News’ May 24 “Revealing the Secret of “Water Hydrogen Fuel Vehicle”, Commercial Gimmick or Feasible Technology”).

　　1℃ reporters found through investigation that the technology Pang Qingnian mentioned is not new in developed countries such as Europe and the United States. “The United States has been conducting research in this area at least 20 years ago.” An authoritative expert who has participated in hydrogen energy research in European and American countries said in an interview with a 1℃ reporter.

　　Hydrolysis hydrogen production technology has been tested repeatedly in developed countries such as Europe and the United States, and was finally determined by the U.S. Department of Energy to have no commercial feasibility in the automotive field. Today, this technology is still lying in the laboratories of these countries.

　　Technology is still in the research and experimental stages

　　Scientifically speaking, hydrogen can be obtained by reacting water, a metal or a metal hydride, and certain catalyst additions with water under acidic or alkaline conditions. The real fuel is actually metal hydride or metal. Water is only one of the reactants. Water consumes metal or metal hydride by participating in chemical reactions to produce hydrogen. Water does not spontaneously turn into hydrogen. Hydrogen production methods using such scientific principles cannot yet be applied in the automotive field. Currently, the only commercial hydrogen vehicles use compressed hydrogen stored in high-pressure hydrogen storage bottles.

　　The "Related Information on the Cooperation between Nanyang High-tech Zone and Youth Automobile Project" issued by the Nanyang High-tech Zone Management Committee shows that the basic principle of the vehicle-mounted hydrolysis hydrogen production technology, which is the protagonist of this "water hydrogen production" incident, is "aluminum alloy powder + catalyst + water" reaction to produce hydrogen.

　　In this regard, the above-mentioned authoritative experts who have participated in hydrogen energy research in European and American countries explained to 1℃ reporters that through repeated tests, foreign countries have long discovered that the specific operating conditions, processes, equipment, and economy, safety, and environmental protection of hydrolysis hydrogen production technology Many indicators such as safety and environmental adaptability show that at present, this technology is not suitable for widespread commercial use in the automotive field.

　　He further explained that hydrogen production from water faces at least three difficult challenges in the automotive field. First of all, the reaction between aluminum alloy powder and water to replace hydrogen cannot use ordinary aluminum materials. A large amount of modifications to the metal aluminum and the addition of additives are required, which is extremely expensive. Secondly, such reactions often need to be effective under acidic or alkaline conditions. A chemical reaction occurs to obtain hydrogen, but this reaction process is highly corrosive, reaction control is difficult, the related equipment has a complex structure, requires high corrosion resistance, and the cost is very high; in addition, the chemical reaction produces The metal hydrate (slurry) product has certain corrosiveness and environmental toxicity, and is not easy to be recycled and reused.

　　1℃ reporters found out by reviewing many academic papers on water hydrogen production from many domestic universities and colleges that at present, hydrolysis hydrogen production technology is still in the research and experimental stage.

　　For example, a paper from the School of Chemistry and Chemical Engineering of South China University of Technology titled "Progress in the Development of Hydrogen Production Technology from Aluminum-Water Reaction" states: "The dense oxide layer on the aluminum surface prevents the contact reaction of aluminum-water to produce hydrogen. In the current situation Among some methods for removing the passivation layer, such as alkali addition method, melting method, alloy method, etc., adding a certain concentration of alkali solution is a fast and relatively effective method. However, the strong corrosiveness of alkali limits it to a certain extent. Therefore, finding a safer and more effective method to remove aluminum oxide is still one of the directions of current research."

　　Although metallic aluminum has high reactivity, there is a dense oxide film on its surface, which hinders the contact reaction between aluminum and water. Therefore, to achieve the aluminum-water reaction, the key is to remove this oxide film.

　　An insider revealed to the 1℃ reporter that the “mysterious” catalyst composed of nanomaterials that Pang Qingnian mentioned has the function of eliminating the dense oxide layer on the aluminum surface to prevent the contact of aluminum and water, speeding up the reaction speed of aluminum and water, and improving the reaction production of aluminum and water. Hydrogen conversion rate.

　　The above statement from the Nanyang High-tech Zone Management Committee shows that the vehicle-mounted hydrolysis hydrogen production technology has been jointly developed by Hubei University of Technology and Youth Automobile since June 2006. It was developed by a team headed by Professor Dong Shijie of Hubei University of Technology. In 2010, it was approved by the Ministry of Science and Technology’s “973 Program” "The project was approved and relevant patents have been obtained.

　　Through inquiries, 1℃ reporters found that a description of "Vehicle-mounted Aluminum Alloy Hydrolysis Hydrogen Production Technology" published on the school's official website stated that in order to increase the aluminum-water reaction speed, the team led by Professor Dong Shijie of the school proposed a method through optimization The composition and preparation process of the hydrogen-producing aluminum alloy are used to obtain a hydrogen-producing aluminum alloy with high activity and achieve rapid hydrolysis to produce hydrogen.

　　The "explanation" also shows that Dong Shijie's team's aluminum alloy for hydrogen production through hydrolysis and its preparation method mainly adopt mechanical alloying, adding a small amount of low-melting point metal and inorganic salts to the metal aluminum powder to prepare an aluminum alloy that can react with water at normal temperatures and pressures. A hydrogen-producing aluminum alloy that reacts with water to produce hydrogen gas.

　　This use is not realistic

　　Also on May 26, Dong Shijie announced to the media that the efficient and low-cost aluminum alloy hydrolysis hydrogen production material developed by the team has obtained 10 authorized patents. "It is a real technological innovation. The United States and other countries also have similar technologies, but our technology is already at the world's advanced level in terms of hydrogen production speed, efficiency and other industrial preparation applications."

　　However, relevant data shows that the current reaction of adding water to new aluminum alloys to produce hydrogen requires very high temperatures, the reaction speed is also very slow, and the conversion efficiency is only 50%.

　　A research report obtained by 1℃ reporters from the National Energy Group, which is entering the hydrogen energy industry, shows that at present, the conventional methods of hydrogen production mainly include: hydrogen production from fossil fuels, hydrogen production from industrial by-products, and hydrogen production from abandoned electricity. The terminal hydrogen price of these hydrogen production methods is comparable to the price of gasoline. This report also did not mention the "water-to-hydrogen" method used by Youth Cars.

　　Different from the time when the Nanyang High-tech Zone Management Committee mentioned the research and development time of "vehicle-mounted aluminum alloy hydrolysis hydrogen production technology" in the above statement, Pang Qingnian claimed that he began to lead relevant technicians to engage in the research and development of water-based hydrogen production technology in 2003.

　　Even so, a domestic hydrogen energy expert who did not want to be named said in an interview with a 1℃ reporter: "The hydrolysis hydrogen production technology of Young Cars has not achieved real innovation and breakthrough. This technology is only developed in European and American countries. Basically, it has just found a use (car), and this use is a direction that has been abandoned by foreign countries, which is not realistic."

　　The hydrogen energy expert added that such chemical reactions often have high requirements for water quality, and it is absolutely impossible to use any water source as claimed by Young Car. Some scholars believe that the reaction products can be reprocessed to produce higher-priced by-products. In fact, this not only involves the need for a complete recovery system, but more importantly, the current recovery of reaction products is only reprocessed at the laboratory stage. Experiments and experimental results show that such a recycling process has problems of high energy consumption and high pollution.

　　"Currently (the "vehicle hydrolysis hydrogen production technology" vehicle built by Youth Automobile) has not yet been put into the market, let alone licensed. It can only be tried in its own factory." On May 25, Pang Qingnian told the media including China Business News the reporter said.
