The mass of a black hole is proportional to its radius, not to its volume like with rocks. So you can’t make a two-dimensional mesh of black holes, only a one-dimensional mesh.
To capture dark energy aka the expansion of the universe, take some masses and let them expand apart, there’s your potential energy. If you ever capture all of it, you can go collect the matter that has stopped expanding away from you.

That sure is a bound on how tight you can make a grid or lattice of black holes.
Yep, that is a way of capturing dark energy. But can you capture enough?
Sure, just put everyone in stasis until the batteries are refilled.
