Hydrogen energy storage is one of the most popular chemical energy storage . Hydrogen is storable, transportable, highly versatile, efficient, and clean energy carrier . It also has a high energy density. As shown in Fig. 15, for energy storage application, off peak electricity is used to electrolyse water to produce hydrogen.
In the meantime the limited use of hydrogen as an energy storage medium for intermittent renewable sources such as wind energy is being explored. A schematic of a hydrogen energy storage system designed to store power from wind and solar power plants is shown in Figure 10.9. Figure 10.9.
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.
Several methods exist for storing hydrogen. These include mechanical approaches such as using high pressures and low temperatures, or employing chemical compounds that release H 2 upon demand. While large amounts of hydrogen are produced by various industries, it is mostly consumed at the site of production, notably for the synthesis of ammonia.
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.
Although the technological cost of hydrogen used for transportation is high because of its long chain and low efficiency from electrolysis water to fuel-cell, the cost of hydrogen used for electric energy storage is low , giving it a competitive advantage in the long-term-fixed large-scale energy storage scenario.
