My source is the German Wikipedia [1], that claims up to ca 60% with sufficient integration, and the fact that Germany managed 50% renewables in 2020 [2] without grid scale battery storage. To be fair, we could rely on the European grid to act as a sort of battery, which is why we managed such a high percentage with very little of the systems integration that the Wikipedia suggests one should do in this phase of the energy transformation.
