Abstract

Die Umsetzung der Energiewende erfordert einen weiteren starken Ausbau der erneuerbaren Energien in Deutschland. Jedoch werden in der energiepolitischen Debatte immer wieder Zweifel geäußert, ob eine weitgehend auf fluktuierender Wind- und Solarenergie basierende Energieversorgung möglich sei. So droht einer aktuell diskutierten Analyse Hans-Werner Sinns zufolge der weitere Ausbau der Wind- und Solarenergie in Deutschland aufgrund fehlen-der Stromspeicher an eine Grenze zu stoßen. In diesem Beitrag wird gezeigt, dass der dabei ermittelte Speicherbedarf aufgrund methodischer Schwächen weit höher liegt als in anderen relevanten Studien. Er kann um rund zwei Größenordnungen niedriger ausfallen, wenn eine moderate Abregelung erneuerbarer Stromerzeugungsspitzen erlaubt wird, wenn also nicht jede von Wind-kraft- und Solaranlagen erzeugbare Kilowattstunde eingespeichert werden muss. Zudem können neue flexible Stromnachfrager den Speicherbedarf noch deutlich weiter verringern. Der Stromspeicherbedarf stellt somit, anders als von Hans-Werner Sinn behauptet, kein Hindernis für den weiteren Fortgang der Energiewende dar.
