China has made new breakthroughs in hydrogen refueling. The number of hydrogen refueling stations built in China continues to rise, and more than 250 hydrogen fuel refueling stations have been built, accounting for about 40% of the world's total. The number of hydrogen fuel filling stations ranks first in the world.

This is the information disclosed by Liu Yafang, deputy director of the Science and Technology Department of the National Energy Administration, at the "China International Economic Exchange Center-United Nations Development Program Hydrogen Energy Industry Summit Forum" recently. In response to climate change, China, like other major economies in the world, attaches great importance to hydrogen energy technology and industrial development. So far, more than 200 hydrogen energy plans and guidelines have been issued by more than 20 provinces across the country. Under the encouragement of the state and local governments, state-owned enterprises, private enterprises and foreign enterprises have shown great enthusiasm for the development of the hydrogen energy industry. Clustering development trend.

In terms of hydrogen production, North China and Northwest China are actively promoting renewable energy hydrogen production projects, and the cost of hydrogen production by electrolysis of water is stable and declining; in terms of hydrogen energy storage and transportation, 20 MPa gaseous high-pressure hydrogen storage and high-pressure tube bundle trailers are mainly transported, and are actively expanding Mixed transportation of liquid hydrogen and natural gas pipelines.

In terms of diversified applications, in addition to traditional chemical, steel and other industrial fields, the pilot application of hydrogen energy in transportation, energy, construction and other fields is also steadily advancing. In the field of transportation, China is currently dominated by passenger cars and heavy-duty trucks. The number of cars using hydrogen fuel cells exceeds 6,000, accounting for about 12% of the global total.

Liu Yafang said that the National Energy Administration attaches great importance to and actively promotes the development of hydrogen energy technology and industry. In recent years, by strengthening top-level design and macro guidance, advancing research on key technical equipment, exploring efficient utilization of multiple scenarios, establishing and improving a standardization system, and actively promoting the development of the hydrogen energy industry.

Zhang Xiaoqiang, executive deputy director of the China Center for International Economic Exchanges, believes that in recent years, the state, local governments and enterprises have continued to increase investment in research and development in the field of hydrogen energy, fully learn from the experience in the development of new energy formats such as wind power and photovoltaics, and give full play to the role of enterprise innovation. . As the main body, it is also necessary to strengthen the integration of high-quality innovation resources, encourage collaborative innovation, and accelerate the breakthrough of key materials and core technical equipment bottlenecks in the entire hydrogen energy industry chain.
