There's a patch between Denmark and Norway which is ~700m deep. This a few hundred kms north of Germany. This is actually closer to most of Germany's wind generation than Bavaria, which is much further south.
I'm not very bullish on the technology however, maintaining anything in the ocean is a difficult challenge. My guess is a mixture of batteries and power to gas would probably wind up being easier to scale up, and cheaper in the long run.
