Among these, chemical energy storage (CES) is a more versatile energy storage method, and it covers electrochemical secondary batteries; flow batteries; and chemical, electrochemical, or thermochemical processes based on various fuels such as hydrogen, synthetic natural gas (SNG), methane, hydrocarbons, and other chemicals products.
The three crucial elements of the chemical energy industry—and therefore of chemical storage—are Carbon (C), Hydrogen (H), and Oxygen (O) . Figure 8.1 shows the chemical structure of organic compounds as well as their combustion products.
The key factors for such kinds of chemical energy storage materials are as follows: Large density; Easy to store and transport; Compatible to the existing infrastructure; Easy to produce and high round-trip efficiency; Environment friendly. Different chemical energy storage materials are listed as follows. Hydrogen.
This again demonstrates the crucial role of chemical-energy storage. It also illustrates that, in comparison with other storage, the energy density of chemical-energy storage is by far the highest. Power plant facilities have coal stockpiles with capacities ranging from several tens of thousands of tons to several hundreds of thousands of tons.
Some of the chemical storage systems which are not yet commercialised can also be listed, such as hydrated salts, hydrogen peroxide and vanadium pentoxide. It is vital to note that chemical energy storage also includes both electrochemical energy storage systems and the thermochemical energy storage systems .
In the course of energy transition, chemical-energy storage will be of significant importance, mainly as long-term storage for the power sector, but also in the form of combustibles and fuels for transport and heat.
