Storing electrical energy in chemical form, via electrolysis in the case of hydrogen, is compatible with the electrochemical storage since chemical fuels have higher energy densities. Hydrogen is not a direct energy source; instead, it is an intermediate energy form and is an ideal candidate as an energy carrier or storage

Electrochemical capacitors. ECs, which are also called supercapacitors, are of two kinds, based on their various mechanisms of energy storage, that is, EDLCs and pseudocapacitors. EDLCs initially store charges in double electrical layers formed near the electrode/electrolyte interfaces, as shown in Fig. 2.1.
Electrochemical energy. Electrochemical energy is what we normally call the conversion of chemical energy into electrical energy or vice versa. This includes reactions transferring electrons, redox reactions (reduction- oxidation). Reduction, when a substance receives one electron. Oxidation when a substance gives away one electron.
