Which types of energy storage devices are suitable for high power 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.
Capacitor, superconducting magnetic energy storage (SMES), supercapacitor energy storage (SCES) are categorized as electric ESDs. On the other hand, sensible thermal storage (STES), latent phase-change material (PCM), thermochemical storage (TCS) are categorized under thermal storage devices.
So far, for projects related to large-scale PVs integration, the Li-ion technology is the most popular solution utilized for energy storage, with a maximum installed energy storage rating at 100 MWh, used for capacity firming and time-shift [101, 104].
What is a hybrid energy storage system?
Hybrid energy storage systems electronically combined (at least two energy storage systems) with complementary characteristics and to derive higher power and energy results, such as a combined electrical-electrochemical system.
On the other hand, sensible thermal storage (STES), latent phase-change material (PCM), thermochemical storage (TCS) are categorized under thermal storage devices. Flywheel energy storage (FES), compressed air energy storage (CAES) and Pumped hydro storage (PHS), are among the common mechanical storage devices.
Methodology used for selection and categorization of ESDs With consideration of the types of energy gathered, ESDs can be grouped into five major groups, i.e., electrochemical, electrical, thermal, chemical, and mechanical energy storage systems.
