The unique advantages of hydrogen energy provide development opportunities for industrial transformation, while the “dual carbon” goals open up greater growth potential for the hydrogen energy industry. However, the prospects for China's hydrogen energy consumption still face some uncertainties. Currently, many low-carbon hydrogen energy technologies are still in the R&D and demonstration stage, and different institutions have varying judgments on the prospects of new technologies and the policy environment of the industry. As a result, there are divergent assessments regarding the prospects of hydrogen energy consumption. This chapter builds upon the scenario setting and path assessment presented in the previous chapter to analyze the demand potential for hydrogen energy in key sectors such as industry, transport, buildings, and power in China.
