The capacitor can only store charge by dielectric separation, so it doesn''t make for very good charge storage in absence of an applied voltage. The counterpoise works, by the way, by acting like a parallel plate capacitor with the other end being the physical earth. It is inferior to actual connections to earth most of the time - but far more

Industry Is it ever useful to add a capacitor between op amp inputs?
Notice that C5 (10nF) is attached across the inputs of IC2B. The poster mentioned that he was only able to achieve stability by adding that capacitor.

Industry Why do electrical sockets need a pin for "grounding". What is this
The purpose of grounding is to give the electricity a superhighway to ground, tripping the breaker right away. The protection is the breaker, all grounding does is make sure it trips if, for example, a bare piece of wire touches the case of the device, for example. If the case were not grounded, it would just sit there live, because the

6 Frequently Asked Questions about “Is capacitor grounding useful ”
Why do I need a capacitor between power and ground?
Capacitors between power and ground is used to suppress spikes. These spikes can damage the board, or at least, the sensitive components. The larger the value of the capacitor, the better the protection. Hope this helps. What is your application/circuit? If it's on a long power line, it could be to just make sure that all AC signals are bypassed.
Can a capacitor be grounded?
In most cases, one side of a capacitor is grounded. However, it is not true that this is the case in all designs. The only guaranteed safe way to discharge a capacitor is through a suitable resistor across its terminals.
Do I need to connect a polarized capacitor to ground?
So for capacitors, if a capacitor is polarized (has a + and - node), then all you need is to make sure that the voltage at the + node is greater than or equal to the voltage at the - node. You do NOT have to connect the - node to ground. YOu still need a decent discharge path on that.
Is a capacitor a ground terminal?
The capacitor is for EMI filtering, it is there to reduce common mode noise. Yes they are ground terminals. One is the ground reference for unisolated mains input side, the other one is the ground reference for isolated low voltage output side. Therefore it must be of special type for safety reasons, the type is called an Y capacitor.
Does grounding a capacitor cause a discharge?
Grounding either pin of a capacitor to frame ground does not necessarily cause a discharge. In fact, it may apply power to some circuit that does not expect it, potentially damaging it.
Why is a ceramic capacitor better than an electrlytic capacitor?
The electrlytic capacitor has high current capacity so that it can carry large spike current when there is any spike in the power supply line. But the frequency responce of the capacitor is less which allows the spike to be present to some extent. The ceramic capacitor is good at frequency response, so it blocks the spike at the output.
