Insolation in Europe is hugely variable, depending on where you are. And that only matters for solar. It’s largely irrelevant for other renewables.
And there’s no compelling use case for hydrogen. It’s a not particularly efficient energy storage medium, with a number of negative attributes (high reactivity, high flammability, extreme proneness to leakage due to the extremely small molecule size). The only motivation for hydrogen is to keep carmakers and car-related supply chain going with minimal reconfiguration. Even then, the energy needed to produce hydrogen exceeds the energy released when it’s used, even without taking into account the energy and environmental costs of transporting it.
