With the in-depth implementation of the dual-carbon strategy

the construction of new power systems mainly based on new energy has accelerated. The proportion of new energy generation has been increasing. The characteristics of randomness

intermittent and fluctuation have posed significant challenge to the long-term electric power and energy balance problems of the power system. In response to the above issues

the advantages and current development status of hydrogen energy are introduced. As a large-scale and long time-scale energy storage technology

hydrogen energy can help solve the long-term electric power and energy balance problem of the new power system. This paper highlights on the electric-hydrogen fusion technology

summarizes the balance problem and solution of long-term electric power and energy

and proposes a technological concept applicable to the Inner Mongolia Power Grid for solving the long-term electric power and energy balance problem of new energy hydrogen production

hydrogen gas turbine and interruptible load. The advantages of the technological concept in economic feasibility

resource reuse

safety support

cross energy storage and development prospects are analyzed

as well as the urgent problems such as high cost

poor safety

and insufficient large capacity storage and transportation capacity. Finally

suggestions and prospects for the future development of electric hydrogen integration are put forward.
