FREMONT, CA: Rising fear for the swelling demand for energy and a fading climate has prompted scientists and researchers to think of renewable energy sources. This occurrence creates favorable opportunities in extenuating greenhouse gas production and constructing innovative electrical models to make the technology reachable worldwide.

However, these sources are intermittent, triggering inconsistencies in supply and demand due to phenomena known as the duck curve’s production. Energy storage systems like batteries, flywheels, and super or ultra-capacitors play dynamic roles in compensating for such discrepancies. Different batteries are being demonstrated and analyzed according to their capacity and usage in grids or industries. Battery management systems carry out various studies on miscellaneous parameters like the state of charge, depth of charge, state of health, and internal resistance to governing the quality. Furthermore, they implement numerous control schemes based on artificial intelligence or machine learning to make these batteries proficient in versatile applications.

At the end of a battery’s calendar period, it can be revamped for a second life, making it significantly more operational for several applications, including powering up residences, communication, and transportation systems. Electric vehicles, being the chief source of second-life batteries, have many capable uses of energy storage systems. The standards, safety concerns, policies, business models, barriers, and possible solutions must be investigated to promote more use of second-life batteries. Proper recycling and disposal procedures ought to be followed after the end of their second life, which is a substance of considerable research interest.

As the traditional electrical infrastructure moves toward a distributed scheme, smart grids and microgrids increase to meet the users’ needs. Energy storage is of chief importance for utility-scale applications and distributed power systems. Storage systems chiefly affect the plans of load leveling and shifting and energy arbitrage in power systems.

Newfangled electric models of power electronic equipment in these systems make grid-tied technologies probable, facilitating the designs of advanced storage systems. As power and energy density differ in distributed systems, different storage equipment fulfills one of the grid resiliency norms. This feature is where hybrid energy storage systems come into play, merging other devices of alternative parts for better-quality steady and transient characteristics. Along with the current storage technologies, numerous advanced battery schemes like solid-state batteries and thin-film Li-ion batteries are studied to make future contributions in energy storage systems.
