Stay tuned.

In a huge container, neatly stacked metal tanks are connected to the pipeline, and electrolyzers and large pure water storage tanks are distributed around the tank, just like a small factory. This is the first (set) of major technical equipment in the energy field of the National Energy Administration and the high-performance megawatt-level proton exchange membrane developed by Jiageng Innovation Laboratory (PEM) electrolytic water hydrogen production equipment.

PEM water electrolysis hydrogen production is currently one of the most environmentally friendly technical routes for hydrogen production, and it is also the only renewable energy water electrolysis hydrogen production method that can meet the EU technical indicators. However, the performance of domestic PEM electrolyzers is generally low and the cost remains high, which limits the large-scale application of this technology.

Not only is the more cutting-edgePEM hydrogen production technology, the current more mature and dominant alkaline water electrolysis hydrogen production technology, also has the problems of high energy consumption and low electrolysis efficiency.

The problem was overcome in Jiageng Innovation Laboratory.

Find ways to bring down the cost of green hydrogen

Hydrogen energy, known"The ultimate energy in the 21st century" is a pure green new energy and an important part of the future national energy system.

This year's government work report proposed to accelerate the development of frontier emerging hydrogen energy, new materials, innovative drugs and other industries. This is the first time that the hydrogen energy industry has been included in the government work report.

However, at present, China's hydrogen production mainly depends on coal, natural gas, oil and other fossil fuels, accounting for nearly70%, industrial by-product hydrogen accounted for about 30%, hydrogen electrolysis water accounted for less than 1%. The latter is the real green hydrogen that can achieve zero carbon emissions in the preparation process.

Industry insiders believe that China is not a question of whether hydrogen is enough, but whether we can produce green hydrogen at low cost, so as to provide an industrial foundation with comparative advantages for the development of hydrogen energy.

Low-cost green hydrogen production not only requires the use of low-cost renewable energy sources such as photovoltaics and wind power, but also relies on electrolytic water hydrogen production equipment to control costs.

"The cost of hydrogen production cannot be reduced, and it is difficult to realize large-scale industrialization of hydrogen energy." Guo Qixun of Jiageng Innovation Laboratory said, "there are many technical routes for hydrogen production from electrolytic water, and we have achieved breakthroughs in key technologies. The reactor data of the alkaline electrolysis water hydrogen production project reached the 2026 industry technical target announced by developed countries in Europe and America ahead of schedule. Proton exchange membrane (PEM) electrolysis water hydrogen production project has achieved self-sufficiency in key materials and its performance index has international competitiveness. The anion exchange membrane (AEM) electrolysis water hydrogen production project has mastered the whole industrial chain technology from material to system. In the first two areas, we have developed megawatt-level high-performance industrial hydrogen production equipment, reaching the international advanced level."

Taking high-efficiency alkaline water electrolysis hydrogen production equipment as an example, Jiageng Innovation Laboratory has developed low energy consumption, low cost and adaptable photovoltaics through the development and process improvement of key materials and core structure of the equipment./1000 standard alkaline electrolytic water hydrogen production equipment for unstable power sources such as wind power.

Guo Qixun introduced, after testing and certification, Jiageng Innovation Laboratory alkaline electrolysis water hydrogen production project output1 The hydrogen of the standard side only needs 3.7 kW hours of electricity, which is 15% ~ 20% lower than the average energy consumption in the industry. At present, 40 sets of 1000 standard alkaline electrolytic water hydrogen production equipment production lines have been built, including high-efficiency electrode production workshop and electrolytic cell assembly workshop.

(next to the third edition)(First Edition)

Committed to creating a world-class brand of hydrogen energy equipment, at present, Jiageng Innovation Laboratory has established an international advanced hydrogen energy working condition testing and technology demonstration platform, hatching high-tech companies such as Chinese businessmen Xiamen Geng, Ludao Hydrogen Energy, Jiameng Technology and Jiaxiong Technology, with an external investment of over 100 million yuan.

Grasp the advantages of Fujian green hydrogen industry development

How does our province plan the green hydrogen industry? The reporter learned that the "Fujian Province Hydrogen Energy Industry Development Action Plan (2022-2025) defines Fujian's development route in the field of hydrogen production, that is, the initial supply of industrial by-product hydrogen is the main, supplemented by renewable energy electrolysis water hydrogen production and nuclear power "valley power" hydrogen production.

Zheng Nanfeng, academician of the Chinese Academy of Sciences and director of the Jiageng Innovation Laboratory, believes that Fujian is particularly rich in offshore wind power resources and has great potential for surplus nuclear power to produce hydrogen. Fujian should give full play to the advantages of renewable energy, learn from the experience accumulated by European countries, carry out large-scale hydrogen production, promote the development of hydrogen energy and solve the problem of electricity consumption.

In 2018, Fujian launched the layout of the provincial innovation laboratory and decided to rely on Xiamen University to build the "Fujian Energy Materials Science and Technology Innovation Laboratory", that is, the Jiageng Innovation Laboratory, to build a national strategic scientific and technological innovation platform with a new system and mechanism.

The layout of the hydrogen energy industry has become one of the main directions of the Jiageng Innovation Laboratory. for our energy security andWith the goal of "double carbon", relying on superior disciplines and major platforms such as chemistry of Xiamen University, Jiageng Innovation Laboratory has made remarkable achievements in hydrogen production technology and equipment.

This has attracted the attention of investors. Wu Xiandong, external director of China Merchants Group, and Deng Renjie, deputy general manager, said that Jiageng Innovation Laboratory has strong basic research capabilities and fruitful research results in the field of electrolytic water hydrogen production technology. China Merchants Group is actively cooperating with it to jointly promote technological innovation and transformation of scientific and technological achievements in the field of electrolytic water hydrogen production technology.

Huashang Xiageng Hydrogen Energy Technology (Xiamen) Co., Ltd. is a hydrogen energy company with independent core technology hatched by both parties. It is a joint venture between Jiageng Innovation Laboratory and China Merchants Group's Hong Kong-listed company, Huashang Energy Technology Co., Ltd. The alkaline water electrolysis hydrogen production project, which has achieved the transformation of results, has been increased by Huashang Energy, and recently won the third session.TERA-Award Smart Energy Innovation Competition Million Dollar Gold Award.

This yearIn March, the Zhangzhou Test Base (12MW) of multifunctional electrolyzed water hydrogen production equipment, one of the most powerful electrolyzed water hydrogen production test bases in China, was completed. With this test base, large-scale verification of water electrolysis hydrogen production equipment is possible.

"Alkaline and PEM water electrolysis hydrogen production equipment requires long-term and in-depth working condition testing and verification before large-scale application." Guo Qixun told reporters that originally limited by power and safety conditions, Jiageng Innovation Laboratory could only build a small test site in its own R & D base, and the verification effect was not good. The completion of the test base will improve the hydrogen industry standards and product verification mechanism to meet the needs of the industry.

Grasping the development of hydrogen energy, Jiageng Innovation Laboratory has conquered the key core technology of electrolyzed water hydrogen production, forming a high-value patent group covering electrodes, diaphragms, hydrogen production devices, hydrogen production equipment and catalysts, membrane electrodes, electrolyzers, testing instruments and methods. In conjunction with well-known schools and enterprises, Jiageng Innovation Laboratory has also successfully applied to the Ministry of Science and Technology.In 2023, the national key research and development plan "hydrogen energy technology key special project" hydrogen production field of all three new projects, supporting funds of more than 0.2 billion yuan.

Explore multi-domain application scenarios of hydrogen

The technological innovation and breakthrough at the production end have been completed. How should the hydrogen produced be used?

With Fuzhou and Xiamen national fuel cell vehicle demonstration and application urban agglomerations as the core, our province is focusing on the demonstration application of hydrogen energy in the field of road traffic. ToIn 2025, the application scale of fuel cell vehicles in Fujian is planned to reach 4000.

In fact, compared with the history of my country's pure electric vehicles from gestation to high-quality development, my country's fuel cell vehicle industry lags behind the pure electric vehicle industry by about10 years, is still in the product introduction period, is entering the application cost of rapid decline in the growth period. This means that in the short term, the use of hydrogen will not increase on a large scale.

If a large amount of green hydrogen is produced, how can it be absorbed? "The State Council on the issuanceThe Notice of the Carbon Peak Action Plan by 2030 clearly stated that the research and development and demonstration application of hydrogen energy technology should be accelerated, and large-scale applications in industry, transportation, construction and other fields should be explored.

Liu Shengjie of Jiageng Innovation Laboratory believes that in addition to the above fields, the most extensive application of hydrogen is the chemical industry. Aiming at this field, the continuous hydrogenation catalytic process developed by Zheng Nanfeng's team can use highly selective catalysts to convert hydrogen into high-value chemicals.

"Catalyst is known as the chemical 'chip'. How to obtain a good catalyst is very important in promoting the progress of the chemical industry." Liu Shengjie introduced that continuous hydrogenation catalytic technology is a process with high production efficiency, stable product quality, and constant and easy control of reaction conditions. It has the advantages of environmental protection, energy saving, and self-control. At present, the continuous hydrogenation catalytic process developed by the laboratory has reached the domestic leading level.

Improving the selectivity and continuity of catalytic reactions is a major strategy for the fine chemical industry to achieve zero emissions from the source, and it is also an important driving force for improving product competitiveness and promoting the upgrading of the fine chemical industry. The continuous hydrogenation catalytic technology is one of the most critical issues in this field, and it is also an important application export in the downstream of the hydrogen energy industry chain.

"Replacing the traditional process of high pollution and high energy consumption with a clean hydrogenation catalytic process can reduce the emission of industrial three wastes by 95% and realize the high-end intelligent development of the application industry. Through the original hydrogenation catalytic technology, it can also significantly improve the monomer purity of all kinds of new materials and reduce their production costs." Liu Shengjie said that now the technology has been successfully applied to the production of new materials such as aramid fiber and polyimide, one of the world's three major high-performance fibers, and is expected to be widely used in aerospace and other fields.

At present, Zheng Nanfeng team's continuous hydrogenation catalytic technology has been selected into the Ministry of Industry and Information Technology's first batch of petrochemical and chemical industry to encourage the promotion and application of the technology product catalog, and has begun to achieve 10,000 tons of industrial production, bringing new output value for enterprises over.1 billion yuan.

The transformation of scientific and technological achievements is an important bridge connecting innovation and industry, and it is also an important link in cultivating and developing new quality productivity. The conversion of green and low-carbon technologies represented by hydrogen energy is a systematic project. At present, in the key projects such as energy storage, hydrogen energy and silicon energy, Jiageng Innovation Laboratory is carrying out the whole chain of core technology research and multi-route promotion of technology research and industrialization.

"Fujian, as a large eastern coastal province, urgently needs to strengthen hydrogen energy technology innovation and applied research, improve industrial layout, build industrial ecology, promote technology maturity and reduce costs through demonstration projects, and create a strong hydrogen energy province with Fujian characteristics." Zheng Nanfeng said that it is necessary to strengthen the hydrogen energy innovation power of advantageous scientific research institutes such as Jiageng Innovation Laboratory and Fuzhou University, promote resource integration, technology iteration and application demonstration, promote the application and promotion of hydrogen energy in new fields and new scenarios, improve the whole hydrogen energy industry chain, and build characteristic industrial clusters.
