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.
This makes it more difficult and expensive to store and transport hydrogen for use as a fuel (Rivard et al. 2019). There are several storage methods that can be used to address this challenge, such as compressed gas storage, liquid hydrogen storage, and solid-state storage.
During the discharge phase, the stored hydrogen is either used in fuel cell or burnt directly to produce electricity. One major drawback in using hydrogen for electricity storage is the substantial energy losses during a single cycle .
The findings demonstrate that incorporating an energy storage system (ESS) can cut operational costs by 18 %. However, the utilization of a hydrogen storage system can further slash costs, achieving reductions of up to 26 % for energy suppliers and up to 40 % for both energy and reserve suppliers.
The foremost approach for storing hydrogen on fuel cell vehicles is by using a high-pressure technique. Notwithstanding its merit, the method suffers from high supply cost, low storage density, and high-risk factors . 3.
