Hydrogen energy is recognized as one of the most ideal clean energy in the world, and it has been paid more and more attention by people. China's hydrogen energy industry is still in the early stage of development, and there are still problems such as weak industrial innovation capability, low level of technical equipment, and industrial development models and paths that need to be further explored. The industry needs to work together to focus on hydrogen production, storage and transportation, and hydrogen refueling infrastructure. Construction, fuel cell distributed power generation, and hydrogen energy replacement in the industrial sector continue to improve the level of key core technologies.

"Currently, the development of hydrogen energy has become the consensus of the global energy transition. Accelerating the development of the hydrogen energy industry is a strategic choice for global climate change, ensuring national security and achieving sustainable development. Hydrogen energy has broad application prospects." A few days ago, at SNEC Hydrogen At the third general meeting of the Energy Industry Alliance, Zhu Kai, President of the Shanghai New Energy Industry Association and Chairman of the SNEC Hydrogen Energy Industry Alliance Council, said that green hydrogen is the definite direction of future development, and the maturity and industrialization of green hydrogen production is a complete priority. A major technological innovation that the world is paying attention to, China is also actively developing and demonstrating related green hydrogen projects.

Under the background of the "dual carbon" goal, the hydrogen energy industry has ushered in rapid development opportunities. As one of the important energy sources for hydrogen production, such as wind and light, renewable energy sources will become the foundation for the integration and coordinated development of wind, light, storage, and hydrogen industries. China's renewable energy installed capacity currently ranks first in the world, and has huge potential in green hydrogen supply. Based on this, green hydrogen production with green electricity has become an industry consensus for the sustainable and healthy development of the hydrogen energy industry.

Support the realization of the "dual carbon" goal

Zhu Gongshan, Chairman of the Global Green Energy Council, Chairman of the Asian Photovoltaic Industry Association, and Executive Chairman of the SNEC Hydrogen Energy Industry Alliance Council, said that hydrogen energy has become an important strategic choice for developed countries around the world to accelerate energy transformation and upgrading and foster new economic growth points. Under the guidance of the carbon neutrality goal of carbon peak, the domestic hydrogen energy industry is booming, and the main technologies and production processes such as hydrogen production, hydrogen storage, hydrogenation, fuel cells and system integration have continued to improve. There are more than 300 industrial enterprises above designated size in the entire industry chain. Family.

"In the first half of 2022, the trend of localization substitution in various segments of the hydrogen energy industry chain will continue to strengthen, and the market share of key materials such as electrolyzers, proton exchange membranes, and catalysts will increase, and costs will continue to decline. According to estimates, by 2025, the scenery The average cost of electricity stored is expected to be stable at around 0.15 yuan, and the green hydrogen production cost will drop to 1 yuan/kg, which strongly supports the smooth realization of the 'double carbon' goal." Zhu Gongshan said.

The "Medium and Long-Term Plan for the Development of Hydrogen Energy Industry (2021-2035)" issued by the National Development and Reform Commission in March 2022 proposed that hydrogen energy will be an important part of the future national energy system. By 2025, the hydrogen production from renewable energy will reach 10- 200,000 tons/year. At the local level, as of now, 30 provinces and municipalities across the country have included the hydrogen energy industry in the "14th Five-Year Plan", and 14 regions have formulated special plans and specific quantitative goals for the hydrogen energy industry.

"With the further maturity of wind power, solar power and other technologies, the output and cost of green power will gradually decrease, and green hydrogen is expected to become one of the important energy sources in the future." said Li Liucan, general manager of Suzhou Xibeiyou Hydrogen Energy Technology Co., Ltd. Therefore, it is particularly critical to upgrade and optimize the performance of traditional hydrogen production equipment, which should further improve energy efficiency and reduce energy consumption, so as to provide better applications for large-scale production of green hydrogen.

Provoking the future of carbon reduction

Zhu Kai said that as the world's largest hydrogen producer, China's annual hydrogen demand is 33 million tons, and the annual output value has exceeded 600 billion. However, at present, the main application of hydrogen is in the fields of ammonia synthesis and methanol synthesis, which accounts for less than 1% in the energy field. According to the forecast of the China Hydrogen Energy Industry Alliance, by 2060, the annual storage capacity of hydrogen in China will reach about 300 million tons, and the application in the industrial field will account for 60%, and the transportation field will increase to 31%.

Wang Yaohui, deputy general manager of Suzhou Xibeiyou Hydrogen Energy Technology Co., Ltd. believes that to increase the proportion of hydrogen used in the energy field, the emission reduction effect of green hydrogen should be fully utilized. fields combined.

Yao Tingting, a Ph.D. from the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, pointed out that since 2010, although the cost of renewable energy power generation has dropped significantly, it is close to the cost of fossil energy power generation, and its proportion in the energy structure has continued to increase, but China's wind and solar resources are rich in resources. There is less overlap between concentrated areas and high energy consumption areas. Therefore, while the proportion of renewable energy is increasing, it is necessary to optimize the allocation.

"In this process, green hydrogen will become an important medium. For pure power supply scenarios with a high proportion of renewable energy, the future must be an energy structure with renewable energy as the main power, and requires energy storage and large-scale stable power sources. Only by forming a support can a controllable and safe power supply of the grid be realized. In this coupled power supply mode, hydrogen energy can exist as an energy storage medium and provide fuel input and output for large and stable controllable power sources.” Yao Tingting Say.

Applaud not to sell urgently need to change

Policies are encouraging and the market is hot, but the hydrogen energy industry still needs more breakthroughs to achieve high-quality development.

Wang Yaohui bluntly said that applauding or not selling is one of the main problems in the current hydrogen energy market. "Although there are many voices calling for the development of hydrogen energy and affirming the industry, the actual landing orders are relatively small. The company planned several wind-solar hydrogen production projects in Inner Mongolia last year, but none of them have yet started."

Bai Zhenhua, a second-level inspector of the Energy Bureau of Inner Mongolia Autonomous Region, told reporters that the main reasons for the failure to meet the project expectations in time were policy and cost. "At this stage, the policy that hydrogen production must be carried out in chemical parks limits the development of hydrogen energy transportation demonstration projects. At the same time, since the second half of last year, the substantial increase in photovoltaic costs has also affected the healthy and orderly development of the hydrogen energy industry."

Zhu Gongshan pointed out that, in general, China's hydrogen energy industry is still in the early stage of development, and there are still problems such as weak industrial innovation capability, low level of technical equipment, and industrial development models and paths that need to be further explored. In the fields of storage and transportation, hydrogenation infrastructure construction, fuel cell distributed power generation, and hydrogen energy replacement in the industrial field, we will continue to improve the level of key core technologies.
