At present, the application scope of hydrogen energy has covered various fields such as transportation, industrial production, energy transfer, power grid energy storage and deployment in China, and is developing towards the energy pillar industry. However, the research on the current situation of hydrogen use is not sufficient. Aiming at the status quo of hydrogen load demand differentiation under the electric-hydrogen coupling scenario, this paper constructs a hydrogen load status quo assessment method based on the ideal matter-element extension model. First, a hydrogen load status quo assessment index system is established. Second, the AHP-entropy weight combination method is used to determine the weights of indicators, and ideal matter-element extension model is constructed for assessment. Finally, the current hydrogen load status of Qinghai Province in 2023 and 2025 is empirically analyzed, and the results show that there is a big gap between the hydrogen load development in Qinghai Province and Shandong Province, especially in the fields of electricity, transportation and heat supply.
