Energy storage refers to the capture and storage of energy produced at one time for use at a later time. Grid balancing, also known as load balancing or grid management, is the process of ensuring that the supply of electricity generated by power plants and other sources matches the demand from consumers and industry [187] .

For each one of the storage solutions presented, we have compared key parameters such as: interaction energy between hydrogen and support, storage capacity, specific energy consumption (SEC). By this work, it is demonstrated that a technology based on clathrate hydrates of hydrogen, while far from being optimized, may be

Energy storage is a critical component of future energy systems where energy waste streams are exploited, energy efficiency is maximized, and fluctuating renewable energy inputs are managed. Many existing and emerging technologies exist to store different forms of energy at a variety of scales and over a variety of storage periods.

In comparison to other storage methods, SMES systems lose the least amount of electricity during the storage process with a round-trip efficiency greater than 95 %. Due to the energy requirements of refrigeration and the high cost of superconducting wire, SMES technology is currently used for short duration energy storage.

3.2 Comparison of Electricity Storage Systems Costs by Cycle Duration. Figure 12.10 shows the range of electricity-shifting costs for a kilowatt-hour with the three most common electricity storage systems according to [ 58 ]: pumped-storage, battery power plants using lithium technology, and PtG using methane.

5.6. Durability (cycling capacity) This refers to the number of times the storage unit can release the energy level it was designed for after each recharge, expressed as the maximum number of cycles N (one cycle corresponds to one charge and one discharge). All storage systems are subject to fatigue or wear by usage.

Therefore, the development of advanced, dependable, and efficient storage methods is essential to achieve a substantial energy density. 62, 63 Despite the growing research focus on green hydrogen production, with over 10,000 publications in 2021, the study 62
