On the economics of electrical storage for variable renewable energy
The rationale is the following: if electricity demand is satisfied, electrical storage can be used to take up renewable surplus energy. Yet integrating increasing amounts of such surpluses requires disproportionately growing storage capacities that are not valuable at most times ( Denholm, Hand, 2011, Schill, 2014 ).
