Abstract
The role of energy storage in ensuring grid flexibility and security of energy supply cannot be over-emphasized. Energy storage technologies harvest the available intermittent power from renewable energy sources in times of excess to be redistributed during scarcity by decoupling energy supply and demand, therefore improving grid flexibility, resiliency, and reliability. Different types of energy storage technologies have been proposed for grid integration of renewable energy sources. This chapter presents an overview of the various storage technologies, providing a comparative analysis of the different energy technologies and their application to smart grids, paying attention to the pros and cons of each of these technologies. This chapter also presents discussions around current developments and trends in this ever-evolving research area. It is important to state that environmental benefits can be provided indirectly by energy storage technologies. It is therefore pertinent to also understand the net environmental impact of the different energy storage technologies.
