The different types of energy storage can be grouped into five broad technology categories: Within these they can be broken down further in application scale to utility-scale or the bulk system, customer-sited and residential. In addition, with the electrification of transport, there is a further mobile application category. 1. Battery storage
Energy storage systems can be classified based upon their specific function, speed of response, duration of storage, form of energy stored, etc. . The classification of ESS based on the form of stored energy is mainly explored here.
Electrical energy storage systems store energy directly in an electrical form, bypassing the need for conversion into chemical or mechanical forms. This category includes technologies like supercapacitors and superconducting magnetic energy storage (SMES) systems.
The simplest form in concept. Mechanical storage encompasses systems that store energy power in the forms of kinetic or potential energy such as flywheels, which store rotational energy, and compressed air energy storage systems. Another emerging option within mechanical storage is gravitational energy storage, which is currently under development.
Energy storage is an enabling technology for various applications such as power peak shaving, renewable energy utilization, enhanced building energy systems, and advanced transportation. Energy storage systems can be categorized according to application.
Energy can be stored in the form of mechanical, electrochemical, chemical, or thermal energy, as well as in the form of electric or magnetic fields. It is also possible to store energy as a hybrid of two different forms. Figure 3 maps out the different ESSs included in this paper, followed by the elaborate discussions on each type. 3.1.

Table 1. Summary of dispatch approaches for energy storage in power system operations. Extended optimization horizon or window of foresight: extend the optimization horizon to consider more than one day at time or add additional foresight (look-ahead window). Straightforward implementation and consistent with current market settings.
Energy storage device constraints The integrated energy system constructed in this paper includes four kinds of energy storage devices, namely CAES, battery, heat storage tank, and gas storage tank.
Energy storage systems (ESS) are widely applied in power grids to absorb renewable energy sources, shift demands, and balance short-term electricity.
A better storage dispatch approach could reduce production costs by 4 %–14 %. Energy storage technologies, including short-duration, long-duration, and seasonal storage, are seen as technologies that can facilitate the integration of larger shares of variable renewable energy, such as wind and solar photovoltaics, in power systems.
Battery energy storage systems (BESSs) are flexible and scalable, and can respond instantaneously to unpredictable variations in demand and generation. They can provide a variety of services for bulk energy, ancillary, transmission, distribution, and customer energy management [1, 2].
The exogenous dispatch model may not accurately represent the optimal operation of energy storage technologies due to necessary simplifications in dispatch model. Stored Energy Value: use the marginal future value of storing an additional unit of energy (usually in $/MWh) to operate the storage devices.

Italian firm Energy Dome uses (liquified by compression) CO 2 drawn from an atmospheric gasholder. Energy is accessed by evaporating and expanding the CO 2 into a turbine. The gas is returned to the atmospheric gasholder, until the next charging cycle. The system can be run in a closed loop, avoiding emissions. In July, 2024, the US Office of Clean Energy Demon.
