With the transformation of the global energy structure and the improvement of environmental awareness, green hydrogen energy, as a clean and efficient form of energy, is attracting increasing attention. Green hydrogen, produced from renewable energy sources such as wind and solar energy, has the characteristics of zero carbon emissions and is one of the key ways to achieve carbon neutrality.
At present, hydrogen production based on fossil fuels leads to high costs and serious carbon emission problems. To meet this challenge, the development of green hydrogen has become crucial. Among the green hydrogen production technologies, water electrolysis technology is favored because of its simple equipment, mature technology and pollution-free. Although the cost is higher and the efficiency is lower, with the advancement of technology and the reduction of cost, its application prospects are broad.
Alkaline water electrolysis technology is currently the most widely used method and has been industrialized. However, its energy efficiency is relatively low. In contrast, the proton exchange membrane (PEM) water electrolysis technology has higher energy efficiency and lower energy consumption, although it is still in the experimental research and development stage in China, its successful application in the international community provides us with reference.
In addition, solar hydrogen production technology, as another important direction of green hydrogen energy, uses solar energy to split water into hydrogen and oxygen, which has the advantages of no pollution and renewable. Although the conversion rate of photocatalytic hydrogen production is low, with the development of efficient, stable and low-cost photocatalysts, its efficiency and economy are expected to be improved.
Biomass hydrogen production technology is also an important part of green hydrogen. The use of biomass resources for hydrogen production has the advantages of abundant raw materials, renewable, and low consumption. The biomass gasification method and pyrolysis hydrogen production technology are relatively mature, but they still face some challenges in practical application, such as the instability of raw materials and technical difficulties in the gasification process.
In order to achieve the widespread application of green hydrogen, policy support and financial investment are key. **Relevant policies should be introduced to encourage the R&D and application of green hydrogen technologies, and provide financial support and tax incentives. At the same time, we will strengthen international cooperation and exchanges to jointly promote the development and application of green hydrogen energy technology.
Popularizing the public is also important, and raising public awareness of green hydrogen can help promote it. By publicizing the advantages and application prospects of green hydrogen, we will guide the public to pay attention to and support the development of green hydrogen. In addition, strengthening talent training and scientific and technological innovation is the key to promoting the continuous innovation and progress of green hydrogen energy technology. Cultivate more professionals, promote the research and development and application of green hydrogen energy technology, and contribute to the sustainable development of mankind. On March 21, 2024, Shanghai will hold the 6th "Tianyang Cup" Petrochemical Corrosion and Protection Technology Seminar. The keynote speech will bring together experts, scholars and industry leaders in the hydrogen energy industry to jointly improve the biggest pain points and blocking points of the hydrogen energy industry chain and low-cost solutions for hydrogen transportation and storage, and give many hydrogen energy solutions for the future clean and efficient energy road.
In short, green hydrogen, as a clean and efficient form of energy, is of great significance for achieving the goal of carbon neutrality and promoting the transformation of the energy structure. In the fields of hydrogen production by water electrolysis, solar hydrogen production and biomass hydrogen production, we need to continue to innovate and make progress to reduce costs, improve efficiency, and promote the wide application of green hydrogen. At the same time, the joint participation and support of enterprises and the public is the key to achieving the sustainable development of green hydrogen. Let us work together to contribute to the sustainable development of mankind.
