Durchbruch für neuartige Stromspeicher: Große und leistungsfähige Redox-Flow-Batterie

(PresseBox) (München, )
Sonne und Wind liefern immer mehr Strom – allerdings unregelmäßig. Leistungsfähige elektrische Energiespeicher sollen das künftig ausgleichen. Fraunhofer-Forschern ist nun ein wichtiger Durchbruch gelungen: Sie haben eine Redox-Flow-Batterie mit einer Zellgröße von 0,5 Quadratmeter entwickelt, was einer Stackleistung von 25 kW entspricht. Das ist achtmal größer als die bisherigen DIN-A4-Blatt großen Systeme. Auf der Hannover Messe stellen sie den neuartigen Stromspeicher erstmals vor (8. bis 12. April).

Sonne und Wind sind wichtige Energielieferanten. Schon heute stammt fast ein Viertel unseres Stroms aus erneuerbaren Quellen. Bis 2050 soll der Bedarf sogar komplett mit Strom aus Sonne, Wind, Biomasse und Co.
