Flow batteries made from iron, salt, and water promise a nontoxic way to store enough clean energy to use when the sun isn''t shining.
For energy storage, the energy density relates the stored energy to the volume of the storage equipment, e.g. the fuel tank. The higher the energy density of the fuel, the more energy may be stored or transported for the same amount of volume. The energy of a fuel per unit mass is called its specific energy.
Likewise, the product of the theoretical energy storage density and published energy efficiency values (ηEE) are a means to predict the real energy storage density (ev,real) achieved with this flow battery after accounting for voltage and faradaic losses. Table I presents values used to assess the Fe-Cr energy storage density.
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.
An alternative to those systems is represented by the liquid air energy storage (LAES) system that uses liquid air as the storage medium. LAES is based on the concept that air at ambient pressure can be liquefied at −196 °C, reducing thus its specific volume of around 700 times, and can be stored in unpressurized vessels.
A key component to assessing the theoretical energy storage density of a redox flow battery is Eeq,cell, which changes as a function of a battery's state of charge (Qsoc). which is the difference between the positive, Eeq,+, and negative, Eeq,−, half-reaction electrode potentials vs the standard hydrogen electrode.
The liquid air storage section and the liquid air release section showed an exergy efficiency of 94.2% and 61.1%, respectively. In the system proposed, part of the cold energy released from the LNG was still wasted to the environment.
