Underwater, pressure resistant generator/motor in 3-10km depth together with moving equipment in a high corrosive environment will be a major issue.
There probably are better ways to store energy, like hydrogen production.

You're right that seawater and the depth are pretty bad for maintenance.
Maybe keep the motor on shore and use a pulley system to feed the cable there.

Yeah, that wouls mean high load pulleys and sealed bearings in seawater and a looooong rope. now just look at the submerged part of a boat that was in the sea for half a year and you'll see another issue with this.

If they are sealed properly and or can withstand the saltwater there's not much that can go wrong with a simple pulley system. If it's moving daily any barnacles and other shit can't really grow on the moving parts.
Just thinking out loud but shouldn't be an impossible feat.

Probably not impossible but one has to look into the cost.
The colder the water the less growth but in warmer waters the "float" will get rather heavy rather quickly

Gigawatts is a unit of power, not energy.

Well spotted!
