A judicious option to substantially reduce the thermal energy costs is to use single-tank thermocline storage systems with molten salts as the direct heat transfer fluid. The thermocline storage system utilizes a single tank that is comparably larger than tanks used in two-tank thermal storage systems. With the number of tanks reduced to one
Hydrogen Energy Storage (HES) HES is one of the most promising chemical energy storages [] has a high energy density. During charging, off-peak electricity is used to electrolyse water to produce H 2.The H 2 can be stored in different forms, e.g. compressed H 2, liquid H 2, metal hydrides or carbon nanostructures [],
Whereas liquid CO 2 and CO 2-based mixture energy storage systems are both closed cycle systems, two storage tanks are typically required for high-pressure and low-pressure fluid storage. However, Chae et al. [25] noticed that the energy density of LCES could be further enhanced by decreasing the number of storage tanks to one.
Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential

The aqueous iron (Fe) redox flow battery here captures energy in the form of electrons (e-) from renewable energy sources and stores it by changing the charge of iron in the flowing liquid electrolyte. When the stored energy is needed, the iron can release the charge to supply energy (electrons) to the electric grid.
