With the promotion of "dual carbon" strategy, China is ushering in a critical period of the socio-economic green transformation. Gradual changes from traditional processes with high energy consumption and emission to green processes with low energy consumption and zero emission are driven by the innovation of energy technology. This paper mainly reviews the media role of hydrogen energy in the green and low-carbon transformations of the hard-to-decarbonize industries and introduces the key technological breakthroughs in the energy field. Finally, prospects for the construction of a multi-energy integration, low-carbon, safe and efficient energy system are presented.
