The cost of the electrical equipment that brings the offshore renewable energy from the wind turbines to the shore is in the same range as the cost of the wind turbines themselves. The future offshore grid will need tens of billions of Euros of investments in HVDC transmission infrastructure. For instance, Dutch-German transmission system operator TenneT has contracted 30 G€ for such connections in the North Sea.

Yes. Those links will be built anyway. Once you have them it isn't a huge stretch of the imagination that you could cross connect them. Check out a map of how many of those we have now, compare with two years ago or so and see how fast the buildout is. North-South links would take care of the seasonal variation and East-West links would lengthen the day.
