Development Prospect of Hydrogen Energy Industry Chain
Like the current construction of the natural gas industry, my country is building a hydrogen energy industrial system such as hydrogen production, hydrogen storage, hydrogen transportation, hydrogenation, and hydrogen use. In view of the challenges of the hydrogen energy industry in terms of technology, economy and layout planning, combined with all aspects of the industrial chain, the following prospects for the future development of hydrogen energy are made.
1) In terms of hydrogen production, hydrogen energy is used as a secondary energy source. To achieve zero carbon emissions in the true sense, its development will inevitably depend on breakthroughs in renewable energy technologies such as solar energy and wind energy. Only through the synergistic reduction of power cost and equipment cost can the economic advantages of green hydrogen be reflected. Compared with smaller countries, my country has a vast territory, with vast desert, Gobi, desert, grassland and sea resources, which can provide abundant renewable energy resources such as solar energy, wind energy, tidal energy, etc., and has inherent advantages in the development of green hydrogen. , can accelerate the realization of the "Hydrogen China" strategy.
2) In terms of hydrogen storage and transportation, the long-distance storage and transportation of hydrogen will be mainly based on natural gas pipelines mixed with hydrogen or newly built pure hydrogen pipelines. The medium and short distances should be combined with various storage and transportation technologies such as ammonia, and developed according to local conditions. With the technological breakthroughs at the hydrogen production end, through the cross-linking of the hydrogen transmission network, it will be widely popularized in the downstream fields of hydrogen energy such as industry, transportation and construction, and the concept of a green "hydrogen economy" will become a reality.
3) In the application of hydrogen, with industry focus and technological development, hydrogen fuel cells are expected to drive changes in applications in the transportation field. In various chemical fields that require hydrogen, such as oil refining, synthetic ammonia, methanol production and steelmaking, green hydrogen will gradually replace gray hydrogen. In many other traditional energy-intensive industries, hydrogen energy will also replace fossil energy as an energy carrier for energy supply. In the field of construction, the use of green hydrogen energy distributed cooling, heating and power cogeneration systems is also an important way to save energy and reduce emissions. At the same time, more hydrogen energy application scenarios will be gradually developed.
