Hydrogen energy generated based on electrolysis requires additional seasonal storage capacity to bridge the gap between fluctuations in hydrogen energy generated from surplus renewable electricity and load demand [13]. The storage of hydrogen energy is mainly divided into physical storage and chemical storage [14].
Storage capacity is the amount of energy extracted from an energy storage device or system; usually measured in joules or kilowatt-hours and their multiples, it may be given in number of hours of electricity production at power plant nameplate capacity; when storage is of primary type (i.e., thermal or pumped-water), output is sourced only with the power plant embedded storage
Compressed Air Energy Storage (CAES): A high-pressure external power supply is used to pump air into a big reservoir. The CAES is a large-capacity ESS. It has a large storage capacity and can be started rapidly (usually 10 min). CAES installation necessitates unique geological conditions. There are restrictions in place all around the world.
Generally, the peak of generation is not coupled with the peak load. Storing this exceeding energy for later use is also an essential task for storage systems.
