The outstanding comprehensive advantages of industrial by-product hydrogen may become one of the main trends in hydrogen production in the short and medium term

Hydrogen energy has the advantages of large reserves, low pollution, high efficiency, carbon-free and sustainable development. It is one of the most promising clean energy sources in the 21st century. In recent years, under the background of energy shortage, environmental degradation and accelerated industrialization, the demand for sustainable and clean energy development has become increasingly urgent. Against this background, the development and application of hydrogen energy have received great attention from the country, and the development of the hydrogen energy market has accelerated.

Hydrogen is a secondary energy source that can be produced using fossil energy, renewable energy and other methods. my country is the world’s largest hydrogen producer. In 2020, the output of my country’s hydrogen industry reached about 25 million tons, of which coal-based hydrogen production capacity accounted for The ratio exceeds 60%, with natural gas hydrogen production accounting for about 20% and industrial by-product hydrogen accounting for 18%.

Coal-to-hydrogen is the main way to produce hydrogen energy in my country, but the carbon emissions of coal-to-hydrogen are relatively high. Under the strategic goals of carbon neutrality and carbon peaking, coal-to-hydrogen technology needs to be further explored. Hydrogen production by electrolysis of water is the cleanest and most environmentally friendly way. However, the cost of hydrogen production by electrolysis of water is high and it is difficult to become the main source of hydrogen energy in a short time. Other hydrogen production methods, such as biomass hydrogen production and photovoltaic hydrogen production, are still in the experimental stage and have not yet reached the level of hydrogen production. Industrial production scale.

In contrast, industrial by-product hydrogen has the advantages of abundant raw materials, low cost, convenient transportation, and mature technology. Moreover, industrial by-product hydrogen can process and reuse industrial waste gas. It is suitable for large-scale promotion and application and is expected to become a future development Key directions. At this stage, my country has become the world’s largest country of industrial by-product hydrogen. Related domestic companies include Bozhou Petrochemical, Zhejiang Juhua Co., Ltd., Satellite Petrochemical, Yangzijiang Petrochemical, Yantai Wanhua, etc. Due to the intensive chemical industry in East China, my country’s industrial by-product hydrogen production capacity is mainly concentrated in East China.

According to the “2021-2025 China Industrial By-Product Hydrogen Industry Market Monitoring and Future Development Prospects Research Report released by the Industrial Research Center It shows that a large amount of hydrogen can be recovered in industrial production processes such as coal coking, chlor-alkali, synthetic ammonia, propane dehydrogenation, metallurgy, and ethane cracking. The total recoverable amount of hydrogen by-product from various industries reaches 1.52 billion cubic meters per year. my country is a major industrial country. In 2020, the output of my country’s coke industry exceeded 450 million tons, the output of the caustic soda industry reached more than 34.8 million tons, and the propane dehydrogenation (PDH) production capacity reached 20 million tons. Using industrial waste gas and other resources to produce hydrogen, my country has With unique advantages.

Industry analysts said that my country is a major industrial country and has unique advantages in developing industrial by-product hydrogen projects. However, due to insufficient attention, industrial by-product hydrogen has not yet been fully utilized, and there is considerable room for improvement in the future. In the short and medium term, industrial by-product hydrogen has certain advantages in terms of production capacity scale, cost economy, production capacity distribution, and utilization space. In the future, industrial by-product hydrogen will become one of the main trends in hydrogen production.
