Energy density is the amount of energy stored in a given system or region of space per unit volume. Colloquially it may also be used for energy per unit mass, though the accurate term for this is specific energy. There are many different types of energy stored in materials, and it takes a particular type of reaction to release each type of energy. In order of the typical magnitude of the energy released, these types of reactions are: nuclear, chemical, en 10277 2 pdf, and electrical.
Nuclear reactions are used by stars and nuclear power plants, both of which derive energy from the binding energy of nuclei. Chemical reactions are used by animals to derive energy from food, and by automobiles to derive energy from gasoline. This section needs additional citations for verification. Note that this list does not consider the mass of reactants commonly available such as the oxygen required for combustion or the energy efficiency in use. In energy storage applications the energy density relates the mass of an energy store to the volume of the storage facility, e. The higher the energy density of the fuel, the more energy may be stored or transported for the same amount of volume. The greatest energy source by far is mass itself.
V, ρ is the mass per unit volume, V is the volume of the mass itself and c is the speed of light. The highest density sources of energy aside from antimatter are fusion and fission. No single energy storage method boasts the best in specific power, specific energy, and energy density. Many researches proposed new options for energy storage to increase energy density and decrease charging time. Note: Some values may not be precise because of isomers or other irregularities. See Heating value for a comprehensive table of specific energies of important fuels.
Note: Also it is important to realise that generally the density values for chemical fuels do not include the weight of oxygen required for combustion. This section may require cleanup to meet Wikipedia’s quality standards. No cleanup reason has been specified. This table lists energy densities of systems that require external components, such as oxidisers or a heat sink or source. These figures do not take into account the mass and volume of the required components as they are assumed to be freely available and present in the atmosphere. Such systems cannot be compared with self-contained systems.
