The actual EU strategy hinges on multiple interacting elements. Making more of the demand steerable, to align peak use better with peak production. Overbuilding renewables capacity so it can still provide enough even at lower efficiency. Wind at sea at a never before seen scale (decided this week at the north sea conference) to have a form of base load (there is dunkelflaute but in general wind at sea is reliable at producing a certain amount of base load). And last but not least the EU hydrogen strategy, where a transport and storage network will be built similar to that for natural gas (in fact converting over that infrastructure), that then can be used to respond to demand in a steerable way, and that can be fed through shipping and pipelines from regions where renewables are most cost-effective at producing hydrogen.
Skeptics like to pretend the EU doesn’t have a renewables strategy beyond hope, but if you dig into it they (like in most things the EU does) have actually worked out a detailed and pragmatic strategy.
