Battery Energy Storage Systems (BESS) Overview of Key Market Technologies

The search for sustainable energy generation, due to non dependency policies on fossil fuels, have grown steadily in recent years, leading several countries to increasingly insert renewable sources in their respective energy matrices. On the other hand, having so many intermittent sources generating energy may cause some problems in the stability and reliability of the grid, which could be solved by using stationary battery energy storage systems. This study provides an overview of the main battery technologies on the market and describes the respective applications and services provided by each on, in addition, a brief analysis is carried out in the main cases of use of battery technologies, based on the energy storage database of the U.S. Department of Energy (DOE). This study also provides a more detailed view at the lithium ion battery, which has already dominated the electronics market and has recently become very attractive in stationary applications.
