A substantial proportion of renewable capacity is already lost to curtailment in the UK, and supposedly this could be reduced by storage. This happens well before renewable generation hits 100% even some of the time for various reasons (transmission capacity bottlenecks, the need for a certain amount of dispatchable power to ensure grid stability, and so on).
