The solar thermal fuels capture the sun’s energy in the chemical bonds between the molecules. This energy can be stored indefinitely forever in the fuel. To better understand the charging and discharging phenomenon, consider this example. Suppose that a normal uncharged fuel molecule is in a ground state A initially. As this molecule absorbs the solar thermal energy, the molecule goes from state A to excited state B. This results in a minor change in the geometry of the molecular structure but no chemical reaction occurs. Such molecules are called “photo-switchable”.
