The type of energy stored in chemical bonds is chemical energy. Chemical bonds are formed with the absorption of chemical energy, and they are broken down with the release of chemical energy.
Chemical energy is a vital component for biological systems. The biochemical reactions that drive essential life processes heavily depend on chemical energy. In the cells of most organisms, chemical energy from biological fuels, such as glucose, are stored in chemical bonds in a process known as cellular respiration. This energy can later be harnessed by the cells to perform various functions. Since chemical energy can be stored indefinitely unless required by the cells, chemical energy is also considered a type of potential energy.
