Driven by the goal of carbon peak and carbon neutrality, hydrogen fuel cell technology has developed rapidly. Many car companies are still unlocking another form of utilization of hydrogen energy-hydrogen engines.

Recently, the Ministry of Industry and Information Technology stated in the "Reply to Recommendation No. 5736 of the Fourth Session of the 13th National People's Congress" that in the next step, it will actively cooperate with relevant departments to formulate hydrogen energy development strategies, and study and promote the inclusion of hydrogen internal combustion engines. support. Hydrogen engines are one of the important technical routes for the application of hydrogen energy in automobiles. The combustion products are mainly water, which is highly environmentally friendly.

The Ministry of Industry and Information Technology also proposed that, as the management department of the automobile industry, the Ministry of Industry and Information Technology will continue to strengthen the construction of the automobile standard system. In the next step, we will further evaluate the adaptability and differences of the current standard system based on the technological progress and application promotion of hydrogen engines, arrange relevant standard pre-research in advance, and promptly promote the formulation of urgently needed standards, which strongly supports the scientific and reasonable development of hydrogen vehicles.

Hydrogen internal combustion engine can be understood as an engine that burns hydrogen. Different from the current very popular hydrogen fuel cell principle, the hydrogen internal combustion engine completes the conversion of chemical energy into mechanical energy according to the four strokes of "inhalation-compression-work-exhaust".

The Ministry of Industry and Information Technology believes that at present, the application of hydrogen energy in the automotive field is mainly fuel cell vehicles. The development of hydrogen vehicles is still in its infancy and may become one of the important application areas in the future.

According to Liu Hanru, general manager of Hanma Technology, my country's existing industrial by-product hydrogen production potential is over 4.5 million tons, which can be directly used in hydrogen engines. Considering reliability, cost, and economy, the hydrogen engine is a very attractive zero-carbon dioxide commercial vehicle powertrain technology solution.

The reporter learned that hydrogen engines can make full use of the existing internal combustion engine industry foundation. At present, some domestic enterprises and universities have achieved some research results in this field. For example, Great Wall Motors released the "Hydrogen Lemon Technology" vehicle-level hydrogen power system full-scene application solution in March this year.

"The boom in hydrogen energy development is coming, but with the emergence of the development boom, the corresponding policies, systems, construction and other aspects need to be matched." Zhang Jiujun, Dean of the School of Science and Dean of the Institute of Sustainable Energy, Shanghai University It is believed that for the follow-up development of hydrogen energy, it is hoped that relevant government departments and industry organizations can clarify the positioning of hydrogen energy, determine the definition and standards of different types of hydrogen, and gradually expand the application fields.
