11 - Potential applications and impacts of solid-state energy storage in power grids

Abstract

With the growing interest in renewable energy and distributed energy resources, energy storage plays a vital role in providing flexibility, resiliency, and reliability to power system operations. The approval of the game-changing US Federal Energy Regulatory Commission (FERC) orders 841 and 2222 in 2020 provided an opportunity for batteries and other energy-storage systems to directly integrate utility-grid operations with and participate in the US electricity markets. Therefore, energy storage with faster charging, more energy density, longer lifespan, and safer operation is required. Unlike conventional batteries with liquid electrolytes, solid-state batteries can overcome the challenges of traditional energy-storage systems and realize the potential of renewable energy generation and distributed energy resources. In this chapter, the development of energy storage in current power systems is reviewed considering renewable energy sources (RES) and electric vehicles (EVs). Applications and impacts of traditional energy storage are also presented. Finally, potential applications and benefits of solid-state energy storage in power systems are discussed.
