Germany Faces Impractical Battery-Only Grid Backup
5.7
A plausibility study published by EIKE and energy expert Staffan Reveman examines whether battery parks could fully secure Germany's wind-and-solar power, finding current storage (≈26 GWh) far short. It estimates 600 GWh for a 10-hour buffer and 12,000 GWh (≈60 million tonnes, 600 km²) for ten days, implying much higher costs and the need for flexible plants or imports.
Key Points
- 1Quantifies storage need: 12,000 GWh required to cover a ten-day German Dunkelflaute
- 2Highlights scale challenges: would weigh ~60 million tonnes and require about 600 km² area
- 3Implies grid planners must keep flexible plants or imports; batteries alone are insufficient
Scoring Rationale
Provides concrete national-scale estimates and implications; credibility limited by single-source analysis and contested EIKE perspective.
