“With the’dual carbon’ goal traction, national policy support, technology maturity, and cost reduction, hydrogen energy is ushering in a period of strategic opportunities for rapid development.” On October 19, Sinopec held the “dual carbon” background in Shanghai Zhao Dong, Director and Deputy Secretary of the Party Leadership Group of Sinopec Corporation, made the above statement in his speech. He said that hydrogen energy has multiple advantages such as high energy density, diverse sources, zero emission of terminals, and a wide range of uses. It is widely regarded as an ultimate energy source and its development prospects are very bright. “But how to choose the development direction of the hydrogen energy industry and what is the development path? How to grasp the timing of optimization and development still requires in-depth research and exploration and practice.”
Focusing on hot issues such as development opportunities, technological innovation, and safe applications of hydrogen energy under the dual-carbon background , Many academicians offered suggestions and suggestions on the forum.
Wang Jiming, an academician of the Chinese Academy of Engineering, said that in order to effectively respond to climate change and protect the ecological environment, green and low-carbon development has become a general consensus of the international community. With the rapid development of a green and low-carbon economy, the rapid development of hydrogen energy, bio-based liquid fuels, and new energy vehicles, the demand for oil has slowed down significantly, and the peak demand is approaching. The peak demand for crude oil is expected to appear between 2030 and 2035. As an important measure to achieve the “dual carbon” goal, green power is an inevitable development trend. “We must vigorously deploy wind and photovoltaic projects, and regions with conditions should make full use of hydropower and nuclear power to maximize the realization of green power. As far as hydrogen is concerned, gray hydrogen is mainly used now, and what we want should be mainly green hydrogen.”
“Decarbonization and zero-carbon in the power industry are the key to achieving the goal of carbon neutrality.” Huang Zhen, an academician of the Chinese Academy of Engineering, believes that if there is no energy reform, there will be no systematic and social Without a green revolution, it is impossible to achieve carbon neutrality. The future energy oriented towards carbon neutrality must be supported by a series of disruptive and transformative technologies. The direction of energy reform in the future can be summarized as the “five modernizations”: on the energy supply side, it includes zero-carbonization of electricity and zero-carbonization of fuels, such as the use of zero-carbon green electricity to produce hydrogen; on the energy demand side, the main directions are electrification and wisdom. And high-efficiency.
Cao Xianghong, an academician of the Chinese Academy of Engineering, said that China’s fuel cell vehicles are in their infancy and will show the following development trends in the future: commercial fuel cell vehicles are the main users; liquid hydrogen and hydrogen pipeline transportation Will be developed; fuel cell industrial power generation will be valued; hydrogen energy storage will become the main energy storage method; gray hydrogen will be the main energy storage method in the near future, and the development of blue hydrogen and green hydrogen will be the medium and long term; hydrogen energy will be gradually developed and utilized in areas that are difficult to reduce emissions .
Tu Shandong, an academician of the Chinese Academy of Engineering, is talking about “the intrinsic safety of hydrogen energy”Utilization” said that hydrogen energy has experienced a wave from science fiction to social industry. Hydrogen was discovered in 1776, and the United States first deployed a hydrogen energy strategy. In 2014, the first hydrogen fuel cell vehicle came out, and countries have followed suit after 2019. However, in the initial stage of development, safety is very important and is a key factor affecting technological progress and industrial development. He believes that the basis for ensuring the intrinsic safety of hydrogen energy is materials. “At present, we urgently need high-strength materials that resist hydrogen damage. The first method of its research direction is to cover with a coating, the second method is to prevent the diffusion of hydrogen inside the material, and the third method is to control the cost of introducing hydrogen resistance in the microstructure. “
Zhang Jiujun, academician of the Canadian Academy of Engineering and Distinguished Professor of Shanghai University, believes that the advantages and challenges of hydrogen production by electrolysis coexist. Its main advantages are in raw water and solar wind power generation. Inexhaustible, inexhaustible; can use the surplus electricity during the trough period to produce hydrogen for energy storage; can obtain high-purity product hydrogen (>99.999%); the reaction speed can be controlled by the cell voltage. Its main challenge It is manifested by low catalyst activity and stability, low energy efficiency (<50%), high hydrogen production cost, high requirements for water purity, and high power consumption.
Sinopec is currently the most active energy central enterprise in the development, promotion and application of key hydrogen energy technologies. According to Zhao Dong, in recent years Sinopec has accelerated the overall hydrogen energy industry chain layout and actively promoted the entire hydrogen energy production, storage and transmission. Chain development and strive to be the leader in green, low-carbon and sustainable development. At present, Sinopec has the largest hydrogen production capacity in China, with an annual output of 3.9 million tons, accounting for 11% of the country’s hydrogen production. During the “14th Five-Year Plan” period, it plans to build 1,000 Hydrogen station makes hydrogen refueling as convenient as refueling. It is actively deploying photovoltaic and wind power hydrogen production projects in Xinjiang, Inner Mongolia and other places. After completion, it is expected to become the world’s largest green hydrogen production project of its kind. At the same time, it will serve as the 2022 Beijing Winter Olympics. As a strategic partner, Sinopec will provide hydrogen supply, vehicle hydrogenation and hydrogen refueling station operation guarantee for the hydrogen fuel cell vehicles for the Beijing and Zhangjiakou Winter Olympics.
