Under the background of the "double carbon", the development of hydrogen energy in my country is observed

In the context of "dual carbon", hydrogen energy has become a key industry that helps low -carbon development and energy transformation and change. The green hydrogen hydrogen technology and liquid hydrogen energy storage prospects are broad, but the latter still needs to break through technology. This is the information upon at the Fourth China Hydrogen Development Summit held in Nanjing on September 6.

Fu Xiaomin, deputy general manager of Beijing Yitong Technology Co., Ltd., predicts that "fuel cell vehicles+green hydrogen" will help my country to achieve about 1.5 billion tons of carbon reduction targets in the future. "As of July this year, my country's fuel cell vehicle ownership has reached 10,561, becoming the country with the most promotion of global fuel cell commercial vehicles. my country is also the country that is most likely to be the first to realize the industrialization of fuel cell vehicles." Fu Xiaomin said. In March of this year, the "Long -term Plan for the Development of the Hydrogen Energy Industry (2021 ~ 2035)" released by my country provides policy support and top -level design for the development of hydrogen energy. At present, the five ministries and commissions have successively approved 5 fuel cell vehicles such as Beijing -Tianjin -Hebei Group, Shanghai Group, Guangdong Group, Hebei Group, and Henan Group. 38 cities participated in it to achieve 10,000 -level demonstration scale.

Gao Jinlin, president of the Chinese Hydrogen Energy Council, said that in the context of promoting the "double carbon" goal, my country's green hydrogen -making technology and liquid hydrogen storage energy can be expected. "If you can achieve higher photovoltaic efficiency and lower power costs, the terminal price of hydrogen at 2030 may drop to 12.5 yuan/kg, and by 2060 to 5.8 yuan/kg." He said that solving energy storage problems is the problem of energy storage. Real -renewable energy uses a large -scale use, while liquid hydrogen energy storage is currently the best hydrogen energy storage method. In terms of energy storage density, liquid hydrogen energy storage is about 3.6 times compressed by hydrogen, and it is 27 times that of compressed air.

"Compared with several other ways, liquid hydrogen storage and transportation volume, higher purity, and lower transportation costs." In response to the advantages of the application of liquid hydrogen, Bao Junxiang, deputy general manager of Hangzhou Zhongtai Cold Technology Co., Ltd., said: "my country At present, the main fuel cell vehicle hydrogen is still compressed by hydrogen, and only a small part of the liquid hydrogen is used for demonstration. However, when the hydrogen refueling station exceeds 1,000 kilograms, it is difficult to meet the hydrogenation of hydrogen. Demand. "

The dean of the research institute of Jiangsu Guofu Hydrogen Energy Technology Equipment Co., Ltd. also pointed out that liquid hydrogen storage operation is a high -efficiency hydrogen storage and transportation method. It has achieved large -scale industrial applications in the United States, Europe, Japan and other countries. Mature. In contrast, my country is currently lagging behind the number of hydrogen liquefied equipment, liquefaction capabilities, technical levels, and key components.

In this regard, experts from China Industrial Gas Industry Association suggested that domestic enterprises and universities combine talent introduction policies to create a good innovation and R & D mechanism, and realize the relevant industrial chain as soon as possible. At the meeting, a number of enterprise representatives introduced the latest achievements in the fields of fixed liquid hydrogen hydrogen storage tanks, liquid hydrogen film tanks, and liquid hydrogen injection.
