Hydrogen energy storage is a form of chemical energy storage that involves electrical power conversion into hydrogen. It is similar in concept to battery energy storage as it works to offset peak electricity demand charges by storing and supplying unused energy when necessary. Stored hydrogen can respect fossil fuel in combustion applications.
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.
The hitch is that, while an excellent medium for renewable energy storage, hydrogen itself is hard to store. This is because it has a low volumetric energy density compared to other gases — such as natural gas — meaning it takes up significantly more space. Also, hydrogen has a boiling point close to absolute zero and requires cryogenic storage.
Chen et al. conducted an economic analysis of a renewable energy system using hydrogen produced by water electrolysis as an energy carrier to overcome the fluctuation of renewable sources. It was determined that a hydrogen-based energy storage system (ESS) is more advantageous economically than a conventional battery storage system.
Some of the common challenges to opportunities of hydrogen storage are highlighted below. 1. Low Energy Density by Volume: Hydrogen has a low energy density per unit volume, leading to the need for efficient storage technologies to store an economically viable amount of energy. 2.
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.
