As a secondary source of energy, hydrogen is playing an increasingly important role on the world energy stage. At present, China has achieved significant progress in hydrogen energy-related technologies, but the hydrogen energy industry remains in the pilot demonstration and market promotion stage.

        Advantages of hydrogen energy, such as its varied sources, zero terminal discharge and wide range of applications. According to the international Hydrogen Council, hydrogen energy will reduce carbon dioxide emissions by six billion tons by 2050. Meanwhile, the China Hydrogen Energy Alliance predicts that by 2050, China's annual hydrogen demand will be close to 60 million tons, which would help the country to cut 700 million tons from its carbon dioxide emissions.

       Since 2020, China has successively issued the “Notice of Launching Demonstration Applications of Fuel Cell Vehicles” and the “New Energy Vehicle Industry Development Plan  (2021-2035),” and supporting plans and policies to promote hydrogen energy R&D, production, storage and transportation and application have been introduced by local authorities across China. As of the end of 2020, China has an inventory of 7,352 fuel cell vehicles, 128 hydrogen refueling stations have been built with 101 already put into operation, ranking second worldwide only to Japan.
