This paper reviews different forms of storage technology available for grid application and classifies them on a series of merits relevant to a particular category.
Are energy storage technologies a viable solution for coal-fired power plants?
Energy storage technologies offer a viable solution to provide better flexibility against load fluctuations and reduce the carbon footprint of coal-fired power plants by minimizing exergy losses, thereby achieving better energy efficiency.
Zakeri and Syri also report that the most cost-efficient energy storage systems are pumped hydro and compressed air energy systems for bulk energy storage, and flywheels for power quality and frequency regulation applications.
What are the different types of energy storage technologies?
An overview and critical review is provided of available energy storage technologies, including electrochemical, battery, thermal, thermochemical, flywheel, compressed air, pumped, magnetic, chemical and hydrogen energy storage. Storage categorizations, comparisons, applications, recent developments and research directions are discussed.
Can energy storage systems be integrated with fossil power plants?
Several studies have been reported in the literature, particularly on power plant system modeling, and integration of sensible and latent heat-based energy storage systems with fossil power cycles, . Liquid air energy storage (LAES) is another form of energy storage that has been proposed for integration with fossil power plants.
Finally, research fields that are related to energy storage systems are studied with their impacts on the future of power systems. Comparison of low speed and high speed flywheel . Energy densities of different metal air batteries . Features of various electrochemical storage technologies .
Can energy storage technologies improve fossil thermal plant economics?
The research involves the review, scoping, and preliminary assessment of energy storage technologies that could complement the operational characteristics and parameters to improve fossil thermal plant economics, reduce cycling, and minimize overall system costs.
