Some common reasons for using capacitors include: Energy Storage: Capacitors store electrical energy in an electric field when they are charged. This stored energy can be released rapidly when needed, making capacitors useful for providing short bursts of power in electronic devices.
Experimental work is under way using banks of capacitors as power sources for electromagnetic armour and electromagnetic railguns or coilguns. Reservoir capacitors are used in power supplies where they smooth the output of a full or half wave rectifier.
A capacitor can store electric energy when it is connected to its charging circuit and when it is disconnected from its charging circuit, it can dissipate that stored energy, so it can be used as a temporary battery. Capacitors are commonly used in electronic devices to maintain power supply while batteries are being changed.
This capacitor stores energy to prevent a loss of memory while the battery is being changed. A common (although not necessarily widely known) example is a camera flash charging. This is why two pictures can't be taken with a flash in rapid succession; the capacitor must build up the energy from the battery.
The amount of electrical energy a capacitor can store is determined by its capacitance, measured in Farads (F) units. The capacitance of a capacitor is determined by the size and shape of the plates and the type of dielectric material used. Capacitors are widely used in various electronic circuits, such as power supplies, filters, and oscillators.
The utility of a capacitor depends on its capacitance. While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed specifically to add capacitance to some part of the circuit.

Capacitor in Electronics
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.

$begingroup$ Another consideration that could be added is that the available power from lightning isn''t really all that much. The power source for lightning is only a tiny fraction of the wind energy that powers the storm - so it would make more sense to extract the power from the wind in the first place, or from the sunlight that ultimately powers the wind. $endgroup$
