How does a capacitor store energy? Energy in Electric Field
A: The energy stored in a capacitor is half the product of the capacitance and the square of the voltage, as given by the formula E = ½CV². This is because the energy stored is proportional to the work done to charge the capacitor, which is equal to half the product of the charge and voltage.

Energy Storage in Capacitor Banks
One is to have a module make up of one or two capacitors with switch mounted directly over the capacitor terminals so that each module has its individual switch. Another is a topology in which a group of capacitors are connected in parallel by a bus bar or parallel plate transmission line and share a start switch placed nearby.
