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.
Energy storage equipment can release energy during peak hours and store energy during valley hours, thus reflecting the role of peak shaving and valley filling. As demonstrated in Fig. 2, the new load curve (red solid line) after energy storage is obtained by removing or filling the energy storage section from the original load demand
However, the disadvantages of using li-ion batteries for energy storage are multiple and quite well documented. The performance of li-ion cells degrades over time, limiting their storage capability. Issues and concerns have also been raised over the recycling of the batteries, once they no longer can fulfil their storage capability, as well as

1. Introduction to energy storage and power systems Electrical energy storage systems have been in use since at least 1870 when Victorian industrialist Lord Armstrong built one of the world''s first hydroelectric power stations at Cragside in Northumberland, UK (Bowers, 1982).).
Energy storage absorbs and then releases power so it can be generated at one time and used at another. Major forms of energy storage include lithium-ion, lead
The energy storage may allow flexible generation and delivery of stable electricity for meeting demands of customers. The requirements for energy storage will
As fossil fuel generation is progressively replaced with intermittent and less predictable renewable energy generation to decarbonize the power system,
The use of electric energy storage is limited compared to the rates of storage in other energy markets such as natural gas or petroleum, where reservoir storage and tanks are used. Global capacity for electricity storage, as of September 2017, was 176 gigawatts (GW), less than 2 percent of the world''s electric power production capacity.
Electrical Energy Storage is a process of converting electrical energy into a form that can be stored for converting back to electrical energy when needed (McLarnon and Cairns, 1989; Ibrahim et al., 2008 ). In this section, a technical comparison between the different types of energy storage systems is carried out.

8. 1. 1. The Storage Opportunity Electric energy storage is poised to become an important element of the electricity grid and marketplace of the future. Similarly, storage use can increase utilization of existing T & D assets, and in some cases it could be used to extend the life of existing T & D equipment – especially aging underground cables.
The storing of electricity typically occurs in chemical (e.g., lead acid batteries or lithium-ion batteries, to name just two of the best known) or mechanical means (e.g., pumped hydro storage). Thermal energy storage systems can be as simple as hot-water tanks, but more advanced technologies can store energy more densely (e.g., molten salts

Traditionally, electricity networks are dimensioned on peak demand. This is inevitable due to the fact that storage of substantial amounts of electricity is technically and economically infeasible. As a result, a vast amount of currently unused network capacity is available. When this could be used, much more energy could be transported with the same
