The increasing competitiveness and critical role of battery energy storage assets in supporting the decarbonization and resilience of the electricity system means that opportunities for energy storage will continue to develop for many years. Continued support from utility regulators and operators are enabling energy storage to realize its enormous potential. Falling prices have made battery energy storage competitive for many applications both on and off the grid.

There are different application characteristics, which underscore the need for different batteries and battery technologies. This advanced battery storage course will provide an in-depth overview of the various types of batteries and address things to consider such as battery characteristics, projected life, performance, and costs.  It will include battery storage applications, utility scale implementations, safety, design considerations, use cases, end-of-life options, and the future of storage.

Learning Outcomes

  • Identify the various types of long duration batteries
  • Discuss different battery chemistry characteristics
  • Discuss the safety hazards to consider
  • Identify the major components in a Battery Energy Storage System (BESS)
  • Discuss the different battery storage applications
  • Review various battery storage use cases
  • Examine the advantages and disadvantages of AC/DC coupled systems
  • Review end of life options for batteries
  • Discuss the future of energy storage
