The "revitalization refueling station" in Nanning, Guangxi was completed and put into operation in Guangxi on December 8, opening up a new way to solve bottlenecks such as hydrogen energy transmission and storage.
Nanning, Guangxi has revitalized an integrated ammonia hydrogenation power station integrating "production, storage, processing and transportation". On this basis, the self-developed "integrated" process of ammonia dehydrolysis and dehydrogenation is used to discharge liquid ammonia into an ammonia storage tank and convert it into hydrogen and nitrogen, which is compressed, separated and purified, and then transported by pipeline transportation vehicles to nearby stations, or directly added to the vehicle.
The storage and transportation of hydrogen is the main bottleneck restricting the development of the hydrogen energy industry. Ammonia decomposition hydrogen production is an important way of hydrogen energy production, compared with the traditional hydrogen refueling station, a new hydrogen ** device has been added, and the design hydrogen ** rate reaches 96%, which can effectively solve the high cost problem in the process of long-distance transportation.
Zhenxing ammonia hydrogenation station is an intelligent control system, including real-time information collection, cloud monitoring, automatic alarm, etc. The hydrogen production plant covers an area of 80 square meters and has a daily production capacity of 99500 kg of 999% high-purity hydrogen, which can meet the requirements of Nanning, Liuzhou and Beihai for automotive hydrogen. In addition, the hydrogen production unit adopts a modular and skid-mounted design, which can be quickly installed and put into production on site, which is convenient for rapid promotion and promotion.

Starting from 2023, a number of departments, including China, have successively issued support policies for the development of China's hydrogen energy industry. Up to now, China has the largest number of hydrogen refueling stations in the world, and has begun the planning of long-distance hydrogen transmission pipelines in China.
At present, China's hydrogen energy industry is mainly concentrated in the Yangtze River Delta, the Guangdong-Hong Kong-Macao Greater Bay Area and the Bohai Rim region. In the fields of hydrogen energy technology innovation, water electrolysis hydrogen production equipment, storage and transportation equipment, fuel cells, etc., we have mastered a series of advanced technologies, and gradually put high-end equipment into the market.
At present, more than 1 3 central enterprises have begun to lay out the industrial chain of hydrogen production, hydrogen storage, hydrogen refueling, hydrogen use, etc., and accelerate the development of key materials and process equipment for the whole hydrogen energy industry chain. Hydrogen in China's chemical industry, represented by synthetic ammonia and methanol, accounts for about 80%. In 2022, synthetic ammonia accounted for about 31% of China's total hydrogen consumption, and if all of it is replaced by "green hydrogen", it can reduce carbon dioxide emissions by 200 million tons per year.
