Abundance of cheap wind energy means that the production of green (through electrolysis) hydrogen comes much closer. Then that will be the way to stockpile energy, rather than having hige batteries installed.

Btw, when building wind parks is a tradeoff or compromise between construction/maintenance costs and kWh yield, then perhaps we ought to build more vertical axis spinning (easier to erect) turbines, at least on sea. Despite the fact that the three-blade design has superior efficiency.
