Abstract: Based on hydrogen energy as one of the important solutions for carbon neutrality in the hard-to-decarbonize industry, the application scenarios of hydrogen energy in transportation, industry, architecture and power electricity were analyzed. Based on the actual annual output of petrochemical and coal chemical products in 2021, the estimated hydrogen consumption in 2021 for existing industrial applications was about 37.9 Mt. In the near to medium term, the domestic hydrogen energy demand pattern is still dominated by coal chemical industry and petrochemical industry. Green hydrogen will gradually penetrate the industrial sector, and the cost of green hydrogen is expected to achieve parity in 2030. Based on the medium and long-term energy outlook model, the total domestic hydrogen consumption is predicted to be about 83 Mt in 2060, accounting for 11.3% of the total terminal energy consumption.
