The different types of energy storage and their opportunities
Key use cases include services such as power quality management and load balancing as well as backup power for outage management. The different types of energy storage can be grouped into five broad technology categories: Batteries. Thermal. Mechanical. Pumped hydro. Hydrogen.
Energy storage systems: a review
Lead-acid (LA) batteries. LA batteries are the most popular and oldest electrochemical energy storage device (invented in 1859). It is made up of two electrodes (a metallic sponge lead anode and a lead dioxide as a cathode, as shown in Fig. 34) immersed in an electrolyte made up of 37% sulphuric acid and 63% water.
