Italy must more than double its capacity to store electricity if it wants to slash pollution from burning fossil fuels, the head of the nation’s power transmission network said.

Terna SpA Chief Executive Officer Luigi Ferraris said Italy may need as many as 6 gigawatts of storage by 2030 to balance a boom in renewables. Storage is one of the ways the grid can balance intermittent flows of electricity from wind and solar farms, which generate only when it’s breezy or sunny.
