Abstract:

2020 was the year of rapid hydrogen energy development. During the seventy-fifth United Nations General Assembly, Chinese President Xi Jinping proposed that China's carbon dioxide emission should peak by 2030 and aim for carbon neutrality by 2060. The decarbonization vision for addressing climate change has gradually become the primary driver of large-scale hydrogen energy deployment. However, the hydrogen industry's development goal and path under the carbon neutrality strategy in China remain unclear. This study analyzes and calculates the demand for hydrogen energy in China's transportation, industrial, construction, and power generating sectors using the scenario analysis method and long-range energy alternatives planning (LEAP) model. The results show that to achieve the carbon neutrality goal in 2060, the annual demand for hydrogen in China will increase from 33.42 million tons to 130 million tons, accounting for 20% of the terminal energy system. With the increasing demand for deep decarbonization and advancements in the low-carbon clean hydrogen economy; hydrogen energy has gradually penetrated the fields of industry, transportation, construction, and power generation. Hydrogen energy supply is gradually shifting away from non-low carbon-hydrogen dominated by fossil energy to clean hydrogen dominated by renewable energy, which will provide 80% of hydrogen energy demand. By 2060, the low-carbon clean hydrogen supply system will have reduced CO2 emission by about 1.7 billion t/a, accounting for about 17% of China's total CO2 emission today.
