Building a hydrogen supply system for production，storage，transportation and refilling，carrying out demonstration operations of fuel cell vehicles，and increasing the proportion of hydrogen production from renewable energy are important ways to achieve the strategic goal of carbon peak and neutrality. Under the guidance of national and local policies，an autonomous，controllable and relatively complete domestic hydrogen fuel cell vehicle industry chain has basically taken shape，and the supporting system of standards，regulations and test and evaluation has been continuously improved. With the continuous expansion of application scenarios，gradual improvement of economy and continuous improvement of hydrogenation infrastructure，the fuel cell vehicle market will embrace rapid development. At the same time，hydrogen and fuel cell vehicle industry development and demonstration application are blooming in many places in China，Beijing-Tianjin-Hebei，Yangtze river delta，Greater Bay Area，Chengdu-Chongqing，Shandong，Henan and other places have formed a certain industrial foundation，and formed their own industrial advantages，automotive hydrogen supply system construction and fuel-cell vehicle demonstration application process is moving forward rapidly. Under the background of the implementation of the “carbon peak and neutrality goals” target，hydrogen fuel cell vehicles have obvious carbon emission reduction benefits，and it is necessary to carry out the research on hydrogen carbon footprint and carbon verification for vehicles as soon as possible.
