On: New island in North Sea to be hub for wind turbine power to 80M Europeans

Submarine power cables use HVDC rather than AC because the capacitance of the water makes the reactive losses of AC transmission a lot higher in that environment. This doesn't affect HVDC.

They're also talking about connecting to multiple separate national grids, which is of course easier to do with HVDC.

thanks a lots. With the keyword HVDC I could find some interesting wikipedia: https://en.wikipedia.org/wiki/High-voltage_direct_current

(I always sought that the entire European grid was synchronous it looks like it's not the case.)
