In chemical energy storage, energy is absorbed and released when chemical compounds react. The most common application of chemical energy storage is in batteries, as a large amount of energy can be stored in a relatively small volume [13]. Batteries are referred to as electrochemical systems since the reaction in the battery is caused by

Introduction. Mechanical energy storage, which is based on the direct storage of potential or kinetic energy, is probably one of the oldest energy storage technologies, along with thermal storage. Unlike thermal storage, mechanical energy storage enables the direct storage of exergy. An attractive feature of the various types of mechanical
Categorically, energy storage technology can be classified into two types based on the method of storage: physical energy storage and chemical energy storage [4]. Physical energy storage encompasses technologies such as pumped storage, compressed air energy storage (CAES), and flywheel energy storage.

Energy storage is a valuable tool for balancing the grid and integrating more renewable energy. When energy demand is low and production of renewables is high, the excess energy can be stored for later use. When demand for energy or power is high and supply is low, the stored energy can be discharged. Due to the hourly, seasonal, and locational
This is defined in Eq. (1), where the total energy transferred into ( Ein) or out of ( Eout) the system must equal to the change in total energy of the system (Δ Esystem) during a process. This indicates that energy cannot be created nor destroyed, it can only change forms. (1) E in − E out = Δ E system.

Over a given time interval [a, b] the energy efficiency relates the accumulated stored/delivered energy to the total invested one (source/storage). With our segmentation of the time in N steps, the time-step is then Δ t = (b-a)/N. Summing up the energies at each time-step for j = 1⋯ N yields the total energy E tot over the interval.
