You need energy to produce a force that compensates gravity. So if you apply that force for a huge amount of time, will gravity ever be depleted?

The short answer to your question is “No.” But what’s really going to screw with you is that gravity isn’t a force – there actually is no such thing as a gravitational force (as we understand it today): [https://www.youtube.com/watch?v=Xc4xYacTu-E](https://www.youtube.com/watch?v=Xc4xYacTu-E)
Gravity, in our everyday human experience, is merely a notional model of reality. It’s a useful model, but it’s not what’s “really” happening.
So, gravity isn’t an endless energy force (actually, it’s nothing, but part of a model of behavior). When energy is expended to change an object’s position, velocity, acceleration in space-time, that energy isn’t working against or compensating for gravity.
