Prospects and characteristics of thermal and electrochemical energy

Generally, energy storage can be divided into thermal energy storage (TES) and electric energy storage (EES). TES are designed to store heat from a source – i.e., solar panels, combustion chambers, gas boilers, waste heat, etc. – in a medium for a subsequent use. On the other hand, EES store electricity and various techniques – e.g
