Batteries: Advantages and Importance in the Energy Transition

Abstract

AbstractWith the growing push toward decarbonization of the electricity generation sector, more attention is paid to storage systems that can assist renewable energy sources (RES). Due to their variability, intermittent RES (such as wind or solar radiation) do not allow a power production distributed uniformly over the short term up to the mid- and long term. Storage of renewable electricity can significantly contribute to mitigate these issues, enhancing power system reliability and, thus, RES penetration. Among energy storage technologies, the potential applications of battery are discussed in this chapter. Focus is placed on applications related to battery energy systems integration in both power systems and electric transportation means.For grid integration, bulk energy services, transmission and distribution network support, and capacity firming coupled to highly variable RES plants are addressed. Regarding transportation applications, electric mobility and perspectives on the interaction of electric vehicles (EVs) with the electric infrastructure are presented and discussed. Finally, this chapter addresses issues related to EVs’ battery aging and their dismission and exploitation as second life batteries in stationary applications.
