Energy capacity (kWh) is the total amount of energy the storage module can deliver. E/P ratio is the storage module’s energy capacity divided by its power rating (= energy capacity/power rating). The E/P ratio represents the duration (hours, minutes, or seconds) the storage module can operate while delivering its rated output.
For example, some reviews focus only on energy storage types for a given application such as those for utility applications. Other reviews focus only on electrical energy storage systems without reporting thermal energy storage types or hydrogen energy systems and vice versa.
Zakeri and Syri also report that the most cost-efficient energy storage systems are pumped hydro and compressed air energy systems for bulk energy storage, and flywheels for power quality and frequency regulation applications.
From the electrical storage categories, capacitors, supercapacitors, and superconductive magnetic energy storage devices are identified as appropriate for high power applications. Besides, thermal energy storage is identified as suitable in seasonal and bulk energy application areas.
To assess the technical performance of various energy storage types, design parameters such as efficiency, energy capacity, energy density, run time, capital investment costs, response time, lifetime in years and cycles, self-discharge and maturity are often considered [149, 150, 152].
Various operating and maintenance (O&M) as well as capital cost components for energy storage systems need to be estimated in order to analyse the economics of energy storage systems for a given location.
