Abstract: Hydrogen is a secondary clean energy which can be stored, moved and controlled. It is an ideal power energy carrier. The development and utilization of hydrogen as an energy source is an important means to tackle the climate change, ensure the national energy security and realize low-carbon transformation of the whole society. As an important greenhouse gas emission industry, the power industry, especially the power generation industry, should develop new energy applications including hydrogen as soon as possible to achieve zero-carbon energy transformation in the industry. According to the requirements of the “double carbon” goal, this paper analyzed the current situation of hydrogen application in China’s power industry, and put forward the main problems existing in the current hydrogen application. Based on the experience of power application development in major international hydrogen countries,combined the requirements of “re-electrification”, this paper put forward suggestions for the development of hydrogen power application from the perspectives of regulation formulation, policy support, financial innovation, and power industry scenario application. That is, during the “14th FiveYear Plan” period, it is necessary to make good technical reserves for hydrogen development, seize the opportunities for industrial development, and actively promote the transformation and upgrading of power system energy.
