CCTV***On December 8, the first commercial distributed ammonia hydrogen production and hydrogenation station in China, Nanning Zhenxing Refueling Station, was completed and successfully put into trial operation in Guangxi, providing a new path to solve the transportation and storage problems faced by the development of China's hydrogen energy industry.
Nanning, Guangxi Province revitalizes the ammonia decomposition hydrogen refueling station, and adopts the integrated whole industrial chain model of "production, storage, processing and transportation". After the liquid ammonia is unloaded into the ammonia storage tank at the station, it is sent to the hydrogen production warehouse, and then decomposes hydrogen and nitrogen through the self-developed "integrated" process of ammonia decomposition and hydrogen purification, and then compresses and separates the purification, and the hydrogen is produced from the hydrogen production warehouse, which can be transported to the surrounding stations or directly added to the vehicle through the tube bundle car.
The key constraint to the development of the hydrogen industry is the transportation and storage of hydrogen. Ammonia decomposition hydrogen production is one of the technical routes for hydrogen production in the station, compared with the traditional hydrogen refueling station, the station has increased the hydrogen production link, and the design hydrogen ** rate is more than 96%, which effectively solves the problems of high cost caused by long-distance hydrogen transportation.
Zhenxing ammonia decomposition hydrogen production refueling station has real-time information collection, cloud monitoring, automatic alarm and other intelligent control functions. The hydrogen production unit covers an area of only 80 square meters and can produce 500 kg per day99999% high-purity hydrogen, which can currently meet the demand for automotive hydrogen in Nanning, Liuzhou, Beihai and other places. In addition, the hydrogen production equipment adopts unit modularization and skid-mounted design, which can be quickly installed and put into operation on site, which is convenient for rapid promotion and replication.
The number of hydrogen refueling stations in China ranks first in the worldSince 2023, the National Development and Reform Commission and other departments have continued to introduce policies to support the development of the domestic hydrogen energy industry. Up to now, the number of domestic hydrogen refueling stations ranks first in the world, and domestic long-distance hydrogen pipelines are being planned and constructed.
At present, the hydrogen energy industry in the Yangtze River Delta, Guangdong-Hong Kong-Macao Greater Bay Area, and Bohai Rim is showing a trend of cluster development. In terms of technological innovation of hydrogen energy, hydrogen production devices by electrolysis of water, storage and transportation equipment and fuel cells, China has mastered a number of advanced technologies, and high-end equipment is gradually being introduced to the market.
More than one-third of the leading enterprises have been laying out the whole industrial chain including hydrogen production, hydrogen storage, hydrogen refueling, and hydrogen use, and accelerating the breakthrough of key materials and core technology equipment bottlenecks in the entire hydrogen energy industry chain. Domestic hydrogen energy, represented by synthetic ammonia, methanol, etc., accounts for about 80% of chemical hydrogen. In 2022, synthetic ammonia accounted for about 31% of total hydrogen consumption, and it is expected that this part of the hydrogen will be completely replaced by green hydrogen in the future, which can achieve an annual carbon emission reduction of more than 200 million tons.
