Three categories of new energy storage

What are the different types of energy storage technologies?

Depending on how energy is stored, storage technologies can be broadly divided into the following three categories: thermal, electrical and hydrogen (ammonia). The electrical category is further divided into electrochemical, mechanical and electromagnetic (Figure 2).

What are the different types of stationary energy storage technologies?

Stationary energy storage technologies broadly fall into three categories: electro-chemical storage, namely batteries, fuel cells and hydrogen storage; electro-mechanical storage, such as compressed air storage, flywheel storage and gravitational storage; and thermal storage, including sensible, latent and thermochemical storage.

How many types of thermal energy storage systems are there?

It was classified into three types, such as sensible heat, latent heat and thermochemical heat storage system (absorption and adsorption system) (65). (Figure 14) shows the schematic representation of each thermal energy storage systems (66). Figure 14. Schematic representation of types of thermal energy storage system. Adapted from reference (66).

How are chemical energy storage systems classified?

Chemical energy storage systems are sometimes classified according to the energy they consume, e.g., as electrochemical energy storage when they consume electrical energy, and as thermochemical energy storage when they consume thermal energy.
