Batteries and an electronic control system are at the heart of how stationary energy storage systems work. Batteries are where the energy is stored within the system in the form of chemical energy, and lithium is the most popular element used to store the chemical energy within batteries.
Chemical energy storage can add power into the grid and also store excess power from the grid for later use. Depending on how it is stored, it can be kept over long periods and is not seasonally dependent like pumped hydro. Many chemicals used for energy storage, like hydrogen, can decarbonize industry and transportation.
Another option with chemical energy storage is to convert electricity into basic chemical materials (methanol) or liquid fuels (power-to-liquid). These liquid fuels would be particularly useful in transport segments requiring high energy densities such as aviation (Fig. 11). Fig. 11.
In energy storage technologies, energy in the form of either chemical, thermal, electric, or kinetic is absorbed and is stored for a period of time before releasing it to supply energy or power services. The energy can be transformed to many different forms for storage: As electric field in capacitors.
Chemical energy is stored in the chemical bonds of atoms and molecules, which is released when a chemical reaction occurs, and the substance is often changed into entirely different substance. Currently, chemical fuels are the dominant form of energy storage both for electric generation and for transportation.
