When discussing the chemical energy contained, there are different types which can be quantified depending on the intended purpose. One is the theoretical total amount of that can be derived from a system, at a given temperature and pressure imposed by the surroundings, called . Another is the theoretical amount of electrical energy that can be derived from In physics, energy density is the quotient between the amount of energy stored in a given system or contained in a given region of space and the volume of the system or region considered. Often only the useful or extractable energy is measured. [pdf]
