Summary: Capacitors for Power Grid Storage. ($/kWh/cycle) or ($/kWh/year) are the important metrics (not energy density) Lowest cost achieved when "Storage System Life" = "Application Need". Optimum grid storage will generally not have the highest energy density. Storage that relies on physical processes offers notable advantages.
If you push into the capacitor a small amount of charge, dQ, then the energy increases by an amount dW = VdQ (energy = charge x voltage) At the same time the voltage increases by an amount dV, where dQ = CdV So dW = CVdV. To get the total energy stored in a capacitor we need to integrate this expression: V.

What is a capacitor? Capacitors are devices which store electrical energy in the form of an electric field. The process is quite similar to the way mechanical springs store energy in the form of elastic material deformation, to the extent that the math describing both is quite similar, save for the variables used.
Supercapacitors (SCs) are those elite classes of electrochemical energy storage (EES) systems, which have the ability to solve the future energy crisis and reduce the pollution [ 1–10 ]. Rapid depletion of crude oil, natural gas, and coal enforced the scientists to think about alternating renewable energy sources.

Capacitors used for energy storage. Capacitors are devices which store electrical energy in the form of electrical charge accumulated on their plates. When a capacitor is connected to a power source, it accumulates energy which can be released when the capacitor is disconnected from the charging source, and in this respect they are similar to batteries.
