The electrolytic cell is the core of the hydrogen storage system, in which electrical energy is converted into heat and chemical water to obtain O 2 and hydrogen. The compressor is used to compress H 2 and store it in the high-pressure gas storage tank [18,19,29]. Fig. 10. Hydrogen storage system.
To actively develop clean hydrogen production methods in the power system, reduce the use of “grey hydrogen” and “blue hydrogen,” and increase the use and development of “green hydrogen”, which is made from renewable energy.
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.
The hydrogen energy storage system is divided into four parts, namely, the power supply module, the electrolytic cell, the compression part, and the high-pressure gas storage, as shown in Fig. 10. From Fig. 5, it can be seen that the power supply module includes a DC/DC buck converter, LC inductor, and capacitor element.
This will aid in decreasing the working and maintenance costs of the production systems. Additionally, the synthesis of innovative materials for hydrogen storage must meet the requirements of elevated volumetric and gravimetric densities (matching the U.S. Department of Energy demands), work at low-temperature values, and enable rapid refueling.
Compared to pumped storage and electrochemical energy storage, it is pollution-free and not affected by the environment. The high energy density and simplicity of storage make hydrogen energy ideal for large-scale and long-cycle energy storage, providing a solution for the large-scale consumption of renewable energy.
