Does China's integrated hydrogen supply and power system have a research gap?

The reviewed studies on China's integrated hydrogen supply and power system development suggested a research gap, where they overlooked the technoeconomic differences of various electrolytic hydrogen production pathways, and often simplified the spatial discrepancies of China's energy system.

What is the role of solar photovoltaic power generation in China?

Among alternative sources, solar photovoltaic (PV) power generation is expected to play an important role in this process in China given abundant solar resources and huge PV manufacturing capacity ( 7 – 10 ).

Does China's integrated hydrogen supply and power system have low-carbon technologies?

This study analyzed the development of low-carbon technologies in China's integrated hydrogen supply and power system under the carbon peaking and carbon neutrality goals in three technology development scenarios using a cost optimization model of the integrated energy system.

Can solid-state hydrogen storage technologies be used in China?

Several projects involving solid-state hydrogen storage technologies have been conducted in China. The Chengdu Hydrogen Collecting Company in China uses high-performance hydrogen storage alloys as solid-state hydrogen storage media.

Does Zhejiang have a high-temperature gas-cooled reactor?

As shown in Fig. 6 b and d for Zhejiang, a coastal province (with high coal prices) allowing for development of high-temperature gas-cooled reactors and solid oxide electrolyzers, has only limited fossil-based hydrogen supply. The electrolyzers are coordinated to adjust their output to fulfill the demand of hydrogen at the lowest total system cost.

Is China a leader in solar power?

With its total installed capacity of solar PV surpassing that of the United States in 2013 and Germany in 2015 ( 15, 16 ), China has maintained its leading global position in terms of not only the deployment of solar power but also the manufacture of PV modules.
