This paper provides a critical review of the existing energy storage technologies, focusing mainly on mature technologies. Their feasibility for microgrids is investigated in terms of cost, technical benefits, cycle life, ease of deployment, energy and power density, cycle life, and operational constraints.
Numerous energy storage technologies (pumped-storage hydroelectricity, electric battery, flow battery, flywheel energy storage, supercapacitor etc.) are suitable for grid-scale applications, however their characteristics differ.
The use of these technologies reduces grid instability, enables sustainable energy integration, and supports energy transitions at a sector-wide scale. While energy storage installations have many advantages, our analysis also highlights some significant limitations, including costs, efficiency limits, and regulatory restrictions.
