Energy density of that solution must be ridiculously low. It's pretty much equivalent to raising water to a certain height.

I really hope you aren't representative of the typical HN reader in terms of evaluation of engineering. That may be true in some pedantic sense, but the practical economics of this is more like what you get from compressed air. The pressures you can achieve wouldn't be as large as in steel tanks, but really large units could be made cheaply and in large numbers. Also, with his weighting scheme, they could be really cheap to deploy, especially for offshore wind, where they already have the mooring rights.
