For a long time, hydrogen has been widely used as a chemical raw material gas in petroleum refining, synthetic ammonia and other industries. In recent years, countries around the world have gradually realized the importance of hydrogen in the energy system and have begun to vigorously develop hydrogen energy. At present, 42 countries and regions in the world have issued hydrogen energy policies, and another 36 countries and regions are preparing hydrogen energy policies. According to the International Hydrogen Energy Commission, the total investment will rise to US$500 billion by 2030.
From the perspective of hydrogen production, China alone produced 37.81 million tons of hydrogen in 2022. As the world’s largest hydrogen producer, China’s current main source of hydrogen is still gray hydrogen, which is mainly coal-based hydrogen production, followed by natural gas hydrogen production (Hydrogen Generation by Steam Reforming) and some HYDROGEN BY METHANOL REFORMING and Pressure swing adsorption hydrogen purification (PSA-H2), and the production of gray hydrogen will emit a large amount of carbon dioxide. To solve this problem, low-carbon renewable energy hydrogen production, carbon dioxide capture, utilization and storage technologies are in urgent need of development; in addition, industrial by-product hydrogen that does not produce additional carbon dioxide (including comprehensive utilization of light hydrocarbons, coking and chlor-alkali chemicals) will receive increasing attention. In the long run, renewable energy hydrogen production, including renewable energy water electrolysis hydrogen production, will become the mainstream hydrogen production route.
From the application point of view, the downstream application that China is currently promoting most vigorously is hydrogen fuel cell vehicles. As the supporting infrastructure for fuel cell vehicles, the development of hydrogen refueling stations in China is also accelerating. Research shows that as of April 2023, China has built/operated more than 350 hydrogen refueling stations; according to the plans of various provinces, cities and autonomous regions, the domestic goal is to build nearly 1,400 hydrogen refueling stations by the end of 2025. Hydrogen can not only be used as a clean energy, but also as a chemical raw material to help companies save energy and reduce emissions, or synthesize high-end chemicals with carbon dioxide.
