WebbEnergy density is the amount of energy that can be stored in a given system, substance, or region of space. [2] [3] Energy density can be measured in energy per volume or per mass. The higher the energy density of a system or material, the greater the amount of energy it has stored. [4] A material can release energy in four types of reactions.
