Impacts of COVID-19 pandemic on electrical energy storage technologies

In this study, the effect of the COVID-19 pandemic on electrical energy storage technologies was investigated. The results of the crises and opportunities created by this unpredictable epidemic in the future processes were evaluated according to energy and especially electrical energy storage areas. Home quarantines used to reduce the spread of the epidemic significantly increased the electrical energy needs of home users. In addition, great changes have occurred in public transportation habits during the COVID-19 pandemic, and it has been observed that approximately 20% of individuals may prefer electric micromobility devices working with lithium batteries due to the risk of infection in closed areas such as public buses or metros. Although the demand for main energy sources has decreased significantly during the COVID-19 pandemic, it is important that the percentage of energy produced from renewable energy sources increases by about 1%. With the increasing use of renewable energy sources and the increasing importance of the concept of sustainability in all areas of our lives, energy storage systems compatible with renewable energy technologies will become more and more important. At the beginning of these technologies, hydroelectric energy storage systems with closed-loop pumps are preferred for large-scale applications.
