Hydrogen energy storage power station participates in auxiliary services

What role does hydrogen play in the development of power systems?

Hydrogen energy, as a zero-carbon emission type of energy, is playing a significant role in the development of future electricity power systems. Coordinated operation of hydrogen and electricity will change the direction and shape of energy utilization in the power grid.

How is hydrogen energy storage different from electrochemical energy storage?

The positioning of hydrogen energy storage in the power system is different from electrochemical energy storage, mainly in the role of long-cycle, cross-seasonal, large-scale, in the power system “source-grid-load” has a rich application scenario, as shown in Fig. 11. Fig. 11. Hydrogen energy in renewable energy systems. 4.1.

Can hydrogen energy be used for seasonal storage?

Due to the seasonal differences in wind power, hydrogen energy can be used for seasonal storage . Hydrogen could store excess electricity during the season when wind power is abundant and wait until the season when wind power is low, which is something that other energy storage cannot achieve.

Why is hydrogen storage important in microgrids?

Hydrogen storage has been proved to have the ability to regulate the frequency regulation of the electric power system in seconds in order to participate in the frequency regulation of power system service . Hydrogen regulation of power grids is now widely used in microgrids .

Does hydrogen storage improve energy storage capacity?

Simulation results demonstrate that considering hydrogen storage results in a significant improvement of the phenomenon of abandoned wind, which also enhances the operating economy of traditional units and storage equipment. This strategy ensures energy storage capacity while simultaneously improving the economic efficiency of the system.

Can hydrogen energy be used in power systems?

The paper first reviews the advantages of hydrogen energy and then systematically discusses the technology of electric hydrogen production with modern power systems. Then, the technical problems and challenges of applying hydrogen energy are summarized, and the future development trend of hydrogen energy in power systems is finally presented. 1.
